The Most Popular Types of Fitness Apps

How to Make a Fitness App: Features
The best fitness tracker apps are rich in features. While creating a fitness app, there are certain features you can’t go without. Read on to learn about them in detail.
Core Features Used to Create a Fitness App
User account & login
User account and login is a must-have feature on your list. If users can’t view personal achievements in retrospect and compare them, then fitness and nutrition apps are useless. A user account can store data, not only on user’s devices, but also in the cloud.
Make it possible for users to register and login through social networks like Facebook, Twitter, Instagram, etc, and sign up via email. If you want to develop a fitness app with on-demand content or a paid subscription, then billing information and an integrated payment system should be present.
User profiles should have fields for data about age, gender, weight, and height. Don't forget to include different units of measurement for different countries, like kilograms vs. pounds, and meters vs. feet.
Wearable connectivity
Wearables, which collect various types of data, have become an integral part of the fitness market. Use HealthKit and Google Fit APIs to access data from Apple Watch and a number of Android gadgets, when you create a fitness app.
These devices gather and store a lot of useful information you can use in your application:

Number of steps and covered distance

Heart rate

Calories burned

Type of exercises

Duration and intensity of physical exercises

Activity tracking
The biggest number of fitness apps are focused on activity tracking. They provide information about steps made, the number of calories burned, distance walked, run, or cycled, time spent on physical activity, and so on. Activity tracking can be done with the help of integral smartphone sensors or using a wearable device.
Goal setting
Goal setting is an integral part of the basic feature set, because users love to set objectives and achieve them. It motivates to move forward and improve physical form.
