Apple HealthKit: Everything you need to know about

The Health App was launched on iPhone and Apple watches on 17 September 2014, by Apple Inc. It is an application that is associated with health informatics, which holds information about blood pressure, blood glucose levels, exercise tracking data such as step counts, and more. The app stores four categories of data such as nutrition, activity, mindfulness, and sleep. The profile of users in the Health app is called the “Medical ID”.

Health app lacked certain features when released with iOS 8. They mainly include incompatibility with third-party apps, poor app performance, improper health information explanation, and more. Later, they were rectified by a software update. The app was made to improve its performance by providing upgrades in the upcoming years. They are,

  • By 2016, users were able to sign up to donate organs, eyes, and tissues in the Health App.
  • In 2018, ECG measurement along with cardiac health monitoring was made possible to the users of the Health app. It was in 2018, Apple introduced “Health Records” on iOS 11.3  where users can store and import their health records from hospitals or doctors.
  • In 2019, tracking facilities such as cycle tracks, monitoring of noise level were introduced along with iOS 13.
  • Finally, as of 2020, the app can store data types such as steps, the distance of walking and run, heart rate, sleep analysis, nutrition, weight, variability, and flights climbed. It was in 2020, the app became compatible with other devices such as La Roche-Posay My Skin UV sensor, Withings smart blood pressure monitorBeddit Sleep monitor,  Withings thermometer, Upright Go 2 posture trainer, and Withings smart scales.

To learn more about the recent updates on the Apple Health app kindly visit, iOS 13 which brings new features to Apple Health App.

Apple HealthKit

Apple HealthKit is an integrated healthcare API introduced in iOS SDK. The API is used by the software builders to develop apps that can coordinate with the health and fitness apps on iPhones and Apple watches. Its logo consists of a white-colored icon with a heart in its center. It enables the users to store data related to the medical, healthcare, and well-being of an individual on the iPhones and allows him/her to access it. It stores the users’ information such as blood pressure level, sleep level, body weight, glucose level, and more. It helps diagnose a user’s level of health and also assists in providing transparent communication between doctors and patients. With the permission of a user, apps on the iPhone communicate with it and access the user’s data while maintaining the security and privacy of the user’s sensitive information. With this app, you can select the task in which you are interested in doing. For example, you can select weight-tracking, pressure level checking, or step-counting from a bunch of tasks available on that app and start doing them. Since the app exchanges your data with your permission, you can easily customize the tasks according to your needs.

Apple’s Ecosystem

Apple lets its users store and track their information in one platform and conveniently access them. For this purpose, it has three products- Healthkit, Researchkit, and Carekit. These three apps form an ecosystem to work with various types of data.

  • HealthKit– This framework lets the third-party applications maintain consistent communication with the Health app. It acts as a container to store different types of data that allows the users to store, access, and collect medical and healthcare information.
  • ResearchKit– This framework collects data from a huge number of people to use the data for research. It has 3 modules:
    • Survey: Researchers use this module to create quick surveys for research purposes.
    • Consent: Researchers will be notified with the details of the research and a form that explains the consent of the participating users through this module.
    • Active Tasks: Through this module, participants will be invited to participate in certain tasks of collecting data about the conditions of the users through iPhone sensors.
  • CareKit– CareKit framework enables the users to manage and keep track of data that is associated with long-term illness, recovery after surgery, chronic conditions, and more. It has 4 modules:
    • Care card: Lets patients take their medications on time.
    • Symptom & Measurement Tracker: Helps patients to track their symptoms and recovery progress.
    • Insight Dashboard: Lets users compare different treatments and analyze which one will be better.
    • Connect: Helps patients share their data with family, friends, and medical staff.

HealthKit DataTypes

HealthKit provides developers variety of data types which is identified by the HKObjectType subclasses. For a simpler understanding of data, they have been divided into vitamins, vital signs, body measurements, minerals, and hydration.  The different data types are:

  • HKCharacteristicType includes information that doesn’t change. This subclass includes data such as skin type, blood type, sex, and birth date.
  • HKCategoryType includes a chosen choice from a list of options (for example, mood after sleep)
  •  HKQuantityType includes numerical values (calories burned, total walking steps)
  • HKWorkoutType includes data associated with workouts (workout type, time)
  • HKCorrelationType represents complex types of data (calories in food items)
  • HKDocumentType helps to make document queries (prescriptions)
  • HKActivitySummaryType represents all information about user activities

HKSeriesType Includes a series of data (for example, data of heartbeat series)

Privacy is a key

Apple aims to provide constant monitoring of the users’ health information via Apple devices in new ways and to connect directly to the EHRs. The app lets you access all your data from a single device. Your information is restricted under Apple’s privacy policy and is encrypted during their storage on iCloud. It is always recommended to review the policies before letting the apps access your sensitive data. iPhones provide Touch ID and Face ID to the users to ensure safe data transfer between the devices.

Future of the Fitness Apps

These fitness apps created a revolution in fitness and healthcare digitally. They eliminate the need for an individual to approach the hospital to give samples to identify their blood sugar levels, pressure levels and to wait for a long time to receive reports in this rapidly moving world.

These apps provide an accurate calculation of data that enables the reduction of risks related to health and life. These apps also provide benefits for the developers as they collect an enormous amount of data which can boost the functionality of future apps.

We nowadays use gadgets for most of our activities. We use them for social media, listening to music, and more. However using gadgets for our benefits, to improve our health, and to keep ourselves fit will be unavoidably compelling to lead a better life.

Python Basics: Functions and Variable Scopes

Python is a general-purpose, high-level programming language that has many applications in web development, data science, software development, and more. It was initially released in the year 1991. Programming in Python involves simple syntax and it works on different platforms such as Windows, Mac, Linux, etc. In this article, we will discuss the Python functions.

Python Functions

A function is a set of related statements written to perform a specific task when it is called. It can take parameters and return a result. It is efficient to use several functions inside a program to perform specific tasks rather than merely writing a large program that performs the entire tasks. Functions are reusable and make the program easy to understand.

Syntax of Python Functions

A simple python function appears like

def func_name(parameters):

/* function statements */

return result

The syntax of a Python function can be defined as follows:

  • The def keyword is used to denote the start of a function header
  • Followed by def, the function name should be written according to the rules of writing identifiers in Python
  • A semicolon should be added at the end of the function header.
  • A function can take one or more parameters as arguments.
  • The statements inside the function should follow the proper indentation as shown above.
  • The docstring (document string) specified inside ” ” ”    ” ” ”  (triple quotes) can be used inside the function to define the purpose of the function. Though optional, it is a good practice to use docstring in your function while writing a program.

For example

def my_name(name):

" " " This function displays my name" " "

print("My name is" +name)

Function call

A function can be called in any part of the program or inside another function, by passing appropriate parameters to it.

>>>my_name('John')

My name is John

If you want to print the docstring of the function, you can print it by using,

>>>print(my_name._doc_)

This function displays my name

Return Statement

The ‘return’ statement is placed at the end of the function that returns either data of a specific type or the evaluated result of an expression. If there is no return statement specified as in the above example function, it returns nothing, or to be more precise, a none object is returned.

def sum(num1, num2):

" " " This function adds two numbers " " "

return num1+num2

print(sum(2,3))

Scope of variables and Lifetime

The availability of a variable whether inside or outside of a function is called its scope. A variable declared inside a function has recognition only inside the function and has no scope outside the function. Such variables are called the local variable. A variable declared on the python program (outside a function) is called a global variable and has a scope on the entire code and also inside the functions. You can also make a local variable global by adding the keyword “global” before the variable name.

Lifetime is the period of a variable that has its existence in memory. Variables declared within the function get destroyed when the function completes its execution. However, the global variables persist as long as the entire program is in execution.

We can see an example for local and global variables

def func1():

a=5 //local variable

return a

b=10 //global variable

c=func1()+b //function call

print("Value=" +c)

Output

15

def func1():

a=5 //local variable

return a

b=10 //global variable

c=func1()+b+a //function call

print("Value=" +c)

If you try executing this function it will show an error message like “name ‘a’ is not defined” as we used the variable outside its scope.

There is also another variable called non-local variables that are used within the nested functions. The non-local variables are declared using the ‘nonlocal’ keyword.

There are two types of functions available in Python. They are:

  • Built-in functions: Functions that are already available in Python. There are 68 built-in functions available in the most recent version of python, Python 3. For example, bin() returns the binary value of a number, ASCII() which returns the Unicode value of a character.
  • User-defined: Functions written by the user.

Types of Function Arguments

The values passed to the function as parameters are called the function arguments. There are two types of arguments. They are

  • Fixed arguments: The number of arguments passed during the function call should be equal to the number of arguments that have been declared to a function during its declaration.

For example,

def func1(num1,num2):

return num1+num2

func1(4) /* throws an error as the number of parameters during the function call is not equal to the number of parameters in the declaration */

  • Variable arguments: There is also another way of declaring variables other than fixed arguments. Variables arguments can be passed using 3 methods. They are:
    • Default arguments by using the ‘=’ operator.
def func1(num1=5,num2):

return num1+num2

func1(4)

func1(4,10)

Output

9

14

The function func1 has two arguments, one with the default value and another without any default value. It is mandatory to pass value to the num2 during every function call but passing a value to num1 is optional as it already has a default value and both the function calls will not throw any error here.

  • Keyword Arguments: Keyword arguments are called with the syntax key=value during the function and the order of the arguments is not important here. You can pass the arguments in any order. They are represented as kwargs in Python.
def func1(num1,num2):

return num1-num2

func1(num1=7,num2=6)

func1(num2=10,num1=17)

Output

1

7

  • Arbitrary Arguments: When we don’t know the exact number of arguments we need to pass to a function during a function declaration, we can assign them during the function call using the ‘*’ keyword.
def students(*stud_names):

print("The students are:")

for name in stud_names

print(name)

students("John","Mary","Harry")

Output

The students are:

John

Mary

Harry

Here we don’t know the number of arguments we are going to pass during the function call, so we use a for loop for retrieval of the values of arguments.

Python Recursive Functions

A recursive function is a function which calls itself during execution.

for example,

def factorial(num):
  if num == 1:
    return 1
  else:
    return (num * factorial(num-1))

number = 5
print("The factorial of", number, "is", factorial(number))

Sometimes it is hard to write a function only using iterations. There we can use recursive functions which are comparatively easier than iterative functions. However, sometimes for complex operations, recursive logic may be hard to understand.

Anonymous Function (Lambda Functions)

So far we have seen functions declared with a name followed by the def keyword. It is also possible to declare functions without a function name by using the lambda keyword and such functions are called the anonymous functions or the lambda functions. They are also used with some of the python built-in functions such as filter() and map().

The syntax of an anonymous function is

         lambda arguments: expression

Arguments can be of any number, but there should be only one expression

int = lambda a: a + 5

print(int(10))

Output

15

In this article, we’ve learned about the functions in python, how to declare them, how to define them, the variables’ scope, their lifetime, types of arguments, and also the anonymous functions.

7 Common Cross Browser Issues Every Developer Face

A website you build will be browsed using different types of browsers by different people across the world. Each browser has its different versions. So if you need your website to be successfully browsed by people without any inconvenience, it should be compatible with different versions of the different browsers. What makes the website incompatible? There are so many issues every developer faces while developing a website that makes it incompatible with the browsers. In this article, we will discuss the 7 common cross-browser issues faced by the developers.

HTML or CSS  Code Specific Errors

Cross-browser testing involves the proper validation of HTML and CSS codes. Invalid codes can be a major problem during the testing. Cross-browser testing expects valid codes since different browsers are going to read and handle them. Developers may have a possibility of making very negligible errors as simple as not closing the tags. Some browsers may auto-correct this, but some browsers cannot. Browsers such as Firefox and Chrome can detect such issues and can resolve them, but some other browsers cannot resolve such issues by themselves.

There are certain issues that are not considered errors, but they behave differently with different browsers. That’s why we should be careful while writing our code. Such kind of issues is discussed below.

  • Commenting on code: If we comment on a specific part of a CSS code that is not useful, it will behave differently with different browsers and can cause issues. So, it is always recommended to remove the unnecessary codes instead of commenting on them.
  • Empty Tags: When you have empty HTML tags in your code, the browsers will take space for them which is unnecessary. It is always the best practice to remove the empty tags or you can give the display property as none to avoid incompatibility with different browsers.
  • Input Tags Font: While handling input tags, always make sure to set the fontFamily property to “initial” to display the input, in the font that you have already used for the body of your content. Otherwise, the input will be displayed in its default font Arial.
  • Button Tags: For button tags in HTML, always make sure to remove the outline and border property as it may behave differently with different browsers.
  • Input elements in Safari: When browsing with Safari, you will find an inner shadow on the top, in all the input elements. To remove the shadow, set border-radius to “0”, webkit-appearance to “none” and webkit-border-radius to “0”.
  • Blurred SVG in Safari: Sometimes, the elements of the SVG image don’t break down while zooming into the image, making the image look blur. In that case, we can replace <img /> tag with the <object> tag, with the “data” attribute containing the image URL.  Ex –
<object data="smiley.svg"></object>

Validation of HTML involves ensuring whether all the tags are properly closed, whether the tags are used correctly according to their purpose, whether DOCTYPE is used, and more. CSS Validation is also the same, whether property names and values are properly spelled, whether curly braces are correctly matched, and so on. To resolve this issue, it is always recommended to use HTML and CSS code validating tools such as W3C HTML Validator and Jigsaw CSS Validator.

Unavailable CSS Resets 

Every browser possesses a specific design layout or some basic styles of CSS that is imposed on the website when opened in it, by default. So, if a website wants to use its specific layout, then it has to override the already available, default layout. Otherwise, the website will be rendered in a different way that depends upon the currently used browser. So, to avoid this a CSS reset style sheet can be used on your web page to ensure whether the browser you are using starts its rendering with the same set of basic rules. Some of the commonly used CSS reset style sheets are HTML5Reset, Eric Meyers CSS Reset, and Normalize.css. Twitter Bootstrapped and many other famous front-end frameworks don’t need an external reset as they already have a reset with them.

Read our article on Getting started with React Native Flexbox Layout

Vendor-Specific Styles 

Each browser has its specific CSS style based on the vendor. Whenever the browser tries to introduce a new CSS feature, it will be coded based on the vendor-specific style. It is essential to avoid the issues of cross-browser compatibility. Different prefixes are used for different browsers to enable the browser vendors to apply their version of the CSS feature. Some of the prefixes are,

  • -moz- for Mozilla
  • -webkit- for Chrome/ Safari
  • -o- for Opera
  • -ms- for Microsoft.

Production websites are never supposed to use prefixed features and they can change or remove without giving any warning and thus results in cross-browser issues. Always be careful while using the prefixed features and make sure whether you are using the correct prefix for a particular browser. You can check the specified prefixes for the browsers on websites like caniuse.com. A simple way to solve this issue is by attaching a prefix-free JavaScript Library to your webpage as it will automatically detect the browsers and add the prefixes accordingly. It can also be resolved by adding prefixes automatically in the process of development, by using tools like PostCSS and Autoprefixer.

Incompatible Layouts 

By implementing CSS Resets, it is possible to remove the default browser designs and to apply our designs. However, this can result in compatibility issues because of adding a non-responsive design (doesn’t looking good in mobile browsers) or because of the inability of certain browsers or their versions to support certain layouts. Layout features don’t provide efficient fallbacks because of simple colors, gradients, or shadows. However, ignoring them completely will make your entire design fall down. It is suggested to use tools like CSS grids and Flexbox when you are working with modern layouts for your website. Most of the modern browsers of today’s age extend their support to these tools and are most effective to use by developers.

It is always recommended to use feature detection as it can detect whether a browser can support the layout features you are going to use. You should be careful while selecting the layout features according to the result you are expecting. For implementing feature detection tests, we can use @supports, a newly introduced feature in CSS.

DOCTYPE Error 

As we know, the very first line in every HTML document will be the Doctype-!DOCTYPE HTML. Missing this single line can determine your entire website. This line determines whether your website will be cleanly rendered or strangely rendered. Whenever a browser behaves differently, make sure to check your Doctype, because missing it may result in faulty rendering.

Generally, a browser operates in two ways or modes. They are Strict Mode and Quirks Mode. Strict Mode performs stricter code checks according to the W3C standards and Quirks Mode doesn’t perform such stricter error checks. Whenever an HTML document misses the doctype line, the browser will go into Quirks Mode. For example, Internet Explorer will go into Quirks mode when it fails to encounter the DOCTYPE and it would have its own web standards in a quite different way. This results in making the webpage display incorrectly and makes some of the tags become unresponsive.

These are the five most common cross-browser issues every developer faces. Apart from these issues, always make sure to check whether the browser is outdated.

Cross-browser Testing 

Cross-browser testing is essential to check whether your web apps and websites run efficiently on different browsers. Websites have to undergo cross-browser testing, in order to be browsed without any compatibility issues on different browsers like Google Chrome, Mozilla Firefox, Edge, and Safari and on different OS combinations.

Cross-browser testing enables you to specifically find out the errors and issues on your website and let you debug those errors quickly. There are two ways of performing cross-browser testing. They are manual testing and online testing. Manual testing involves testing the websites manually on all browsers. For that, you need different browsers to be installed on your device. This process consumes a lot of time and sometimes it is inefficient because of different versions of the browsers.

Another yet powerful method is testing through tools available online. This method involves testing the website on an online testing tool that has different browsers along with different versions on their servers. This method saves your time as well your effort and money and makes the testing process simple. There are some tools available online to test your website for cross-browser compatibility. One such tool is the Lambda test.

  •  LambdaTest 

LambdaTest is an online cross-browser compatibility testing tool, that allows your website to be tested across locally or publicly hosted websites and on more than 2000 mobiles and browsers running on a real OS. It also lets you debug codes using the integrated debug tools in real-time. LambdaTest provides a lot of features along with browser testing such as,

  • Selenium Automation Testing
  • Provides automated test screenshots
  • Ensures whether your website runs efficiently on all screen sizes
  • For testing the locally hosted pages, it uses Tunnel
  • Visual Regression Testing
  • Testing for Resolution display
  • Geolocation testing and more.

LambdaTest also allows integration with third-party apps. This tool remains helpful for many to test their websites and to improve the performance of their websites and web applications.

Top 5 Tips For Developing an App on a Budget

Building a mobile app for your business is essential in this modern era, right? Then what next? Developing an app on your budget is doubtful. It’s never cheap! However, it is critical to promote your business to the next level by creating a mobile app. So, what can we do to develop an app that best fits your business, at the same time on a limited budget? In this article, we will discuss some important tips that help you develop a mobile app that is cost-effective, and on your estimated budget.

Clear objectives and Resources

You can have a variety of reasons to build an app for your brand. However, you should clear with them. There may be different features and strategies you can have or use in your application. What am I going to build an application for? What is my plan for implementing this? What are my and my user’s expectations about this app? Be clear about all these questions before starting to developing your app. If you’re strong with your plan, then developing the app within the estimated time and budget will be a less constrained job for you.

Always have a well-defined plan for your app and start working according to that. Have a clear estimate on the expenses for both development and marketing. Make sure you allocate your time and budget for advertising and linking on social media, to make your application stand unique in the crowd!

Try an MVP

One of the best things to do before developing a fully functional app is to create an MVP (Minimum Viable Product). It is the best alternative product, which offers minimal features essential for release and testing, and lets your targeted audience provide your feedback, suggestions, and reviews before going to develop your main application. MVP is a cost-effective prototype and can be built within a short span of time.

The main purpose of creating an MVP is to learn about the functionalities of your fully-featured app and gain knowledge about your final product. Applying the necessary changes you learned from analyzing your MVP to your final product results in a better functioning app with enhanced performance and with a limited budget. It is necessary to have a clear objective and understanding of the requirements of your business application. This will help you to efficiently utilize the MVP to get a great application for your business.

Selecting the Right Platform

If you’re aiming to release a mobile application on a limited budget, it is always good to go with a single platform. Aiming to build an app for all platforms at the first stage itself, will be too expensive for all. Without knowing how your main application will look like, how it will perform, it is not a good thing to develop it for all platforms. You should be clear about which platform you’re going to develop your app for. Developing an app for androids will be expensive as there are plenty of Android devices available nowadays, with different screen sizes and versions.

However, iOS has a limited number of devices with a specific range. For example, successful apps like Instagram, Foursquare aimed in building for only platform iOS, and after achieving huge success, they transformed their apps to be also available on the Android platform. Pick a platform, develop an app specifically for that platform, analyze your app’s performance, features and flaws, then transform it to be available on multiple platforms in the future.

Make a simple design

Keep your app’s design simple and hassle-free to navigate, attract users, and save your money. Your app should be more clear for the users to understand what you’re offering for them. Simpler apps save your time, and won’t require much graphics and animation. However, try to give a neat and decent UI for your clients. If you aim to build a cost-effective app and also to achieve user satisfaction, keep your app less complicated to interact with.

Team and Partnership

Creating an app individually for your business doesn’t sound right. You will need a team to work towards developing an efficient app for your business. Either hiring experienced app developers or giving your project to an app development company will help you achieve this. Again, hiring experienced developers will not be a cost-effective option for development. Be smart and choose according to your business requirements.

A partner who offers the best support while app development is appreciable. Partnerships with a freelancer, an organization, or an entrepreneur can be made to get support for your app development process. Getting support from people who are already well-established or experienced in your field will definitely help you in achieving success.

These are some of the useful tips you can follow while developing a cost-effective app for your business. It is always recommended to hire a mobile application developing company that best suits your requirements and budget. Always be clear about your financial restrictions to the company and your business needs.
