Fitness (app)

Fitness is an app developed for iOS, iPadOS, and watchOS by Apple Inc.

Description
The Fitness app was announced on September 9, 2014 and was released with the first Apple Watch on April 24. At the time, it also need to be operated in conjunction with an iPhone running iOS 8.2 or later. As of September 20, 2021, the latest version available (1.3.7) requires iOS 11 or later. It displays activity metrics in the form of "rings" to help the user visualize daily activity targets. Accelerometer and gyroscope data from an Apple Watch is gathered to calculate the user's motion. Starting with the release of iOS 16 in 2022, the Watch will no longer be required as this data would be able to be calculated from the sensors within supported iPhone models alone.

The app can also be used with the Apple Fitness+ subscription service, introduced in December 2020, to coordinate workouts with videos produced by Apple with professional trainers.
