Top 10 Fitness APIs

There is no doubt recently adopted technologies have changed the fitness industry. Mobile applications and wearables are available to track sports & activities, calories, heart rate, standing, sitting, and climbing stairs vs. taking the elevator, nutrition macros, sleep cycles, and even blood sugar. All this available data has upped the game for the Fitness industry, and driving this innovation are Application Programming Interfaces, or APIs.

Developers looking to create applications for keeping fit should check out the Fitness category on ProgrammableWeb. There, they can find the best APIs for their app from a huge directory curated by our API researchers.

In this article, we reveal the top ten Fitness APIs, chosen by total page visits on ProgrammableWeb.

1. Fitbit API

Healthkit strives for data sharing for health purposes while maintaining the user's privacy and control.

5. BMI Calculator API

The BMI Calculator APITrack this API offers developers a calculator to determine Body Mass Index (BMI) in software applications. BMI is a measure of body fat based on height and weight that applies to adult men and women. The API allows JSON inputs only.

6. Garmin Health API

The Garmin Health API enables developers to leverage health and activity data from Garmin wearable devices. It is intended to be used for such applications as corporate wellness, population health, and patient monitoring. There are methods available to collect data about steps, sleep, calories, heart rate, stress, intensity minutes, body composition and more. Thirty types of activity are monitored including running, cycling, paddle boarding, swimming and more. User consent is required for data retrieval. Documentation is available to registered developers.

7. FatSecret Platform API

FatSecret provides tools to achieve diet goals. The FatSecret Platform APITrack this API enables access to a large food and nutrition database.
