Step By Step Guide To Implementing Android Google Fit And iOS Health Kit

Living a healthy life is a modern and prevalent trend, which is increasing the market for fitness tracking apps. Basically, tracking apps are designed to track and analyze user daily activity information and notify them about their activity targets and achievements. Built upon the data, a company can offer an excellent mobile solution to customers that allows customers to do more with the data.

No surprise that Google and Apple are working directly on several fronts to piggyback on the opportunity. Whether in terms of wearables, the Internet of things, mobile applications or mobile OS — there is a massive competition between both.

Google introduced its healthcare platform ‘Google Fit’, which utilizes its APIs to track its fitness activities. With iOS 8, Apple launched the Health Kit framework that works alongside its health apps.

What Is Google Fit?

Google Fit is a health-tracking platform developed by Google for Android. Google Fit uses sensors in a user’s activity tracker or mobile device to record physical fitness activities (such as walking, cycling, etc.).

In the first part of this article, we will cover the built-in framework provided by Google. To develop such applications, you require technical knowledge and a clear understanding of the components.

Google Fit Components

  • The Fitness Store- A central repository that stores data from a variety of devices and apps. The fitness store is a cloud service that is available to clients.
  • The Sensor Framework- A set of high-level representations that make it easy to work with the fitness store. You use these representations with the Google Fit APIs.
  • Permission and User Controls- A set of authorization scopes to request user permission to work with health and wellness data.
  • Google Fit API- Android and REST APIs to access the fitness store. You can create apps that support Google Fit on multiple platforms and devices, such as Android, iOS, and Web apps.

Type Of APIs

The Google Fit APIs for Android are part of Google Play services and are supported in Android 2.3 (API level 9) and higher. Google Fit on Android consists of these APIs:

  • History API- The History API enables your app to perform bulk operations on the fitness store: reading, inserting, updating, and deleting historical health and wellness data.
  • Sensor API- The Sensors API provides access to raw sensor data streams from sensors available on the Android device and sensors available in companion devices, such as wearables.
  • Recording API- The Recording API provides automated storage of health and wellness data using subscriptions. Google Fit stores health and wellness data of the specified types in the background and persist app subscriptions.
  • Session API- The Sessions API provides functionality to store health and wellness data with session metadata. Sessions represent a time interval during which users perform a fitness activity.
  • Goals API- The Goals API provides a way to track users’ goals for their health and fitness progress.

Steps For Implementation

  • Settings on the Google Console
  1. Go to Google Search Console.
  2. If you have a Google Analytics login, then use the exact details. If you don’t have the account in that case, you need to login first.
  3. Once you have completed the login process, click the button called “Add A Property” top of the page.
  4. To continue the process, Enter the correct URL of your website
  5. Next, you will be asked to verify that you own the website in one of four ways
  6. If you already have a Google Analytics Tracking ID installed, and we would highly recommend that you do, then setting up
  7. Google Search Console is very easy. Simply click the Verify button, and that’s it!

We Simplified The Language Tracking Process For A Travel Application

  • Android Project Setup
  1. Install the latest version of Android Studio.
  2. In the Welcome to Android Studio window, click Create New Project.
  3. If you have a project already opened, select File > New > New Project.
  4. In the Select, a Project Template window, select Empty Activity and click Next.
  5. In the Configure your project window, complete the following:
  • Enter “My First App” in the Name field.
  • Enter “com.example.myfirstapp” in the Package name field.
  • If you’d like to place the project in a different folder, change its Save location.
  • Select either Java or Kotlin from the Language drop-down menu.
  • Select the lowest version of Android your app will support in the Minimum SDK field.
  • If your app will require legacy library support, mark the Use legacy android. Support libraries checkbox.

Leave the other options as they are.

6. Click Finish

Connect to the fitness service

  • Get the necessary OAuth authentication-
  • Get the necessary Android permissions
  • Create an API client and use API’s

What Is HealthKit?

HealthKit is a central repository for health and fitness data on iPhone and Apple watch. The Healthcare framework was introduced in 2014 alongside iOS 8. It provides a solution for storing, managing, and sharing health and fitness data within new applications with the user’s permission to maintain security.

How Does It Work?

Accessing & storing health & fitness data

There are three main ways to access data from the HealthKit Store to the fitness service.

  • Direct method call
  • Queries
  • Long-running queries

Saving Data to HealthKit

  • Create & Share Healthkit samples
  • Save data

How To Implement Apple HealthKit?

  • Enable HealthKit for your app into Xcode
  • Ensure that HealthKit is available on the current device
  • Create your app’s HealthKit Store
  • Request user permissions to read and share data
  • Access and share data with your Store by using predefined classes and Data Types provided by HealthKit Store.
