For a long time, the fitness application on iPhone has been used as an activity tracking tool for AppleWatch users, but in iOS 16, Apple wants the application to publish activity tracking options, even if there is no AppleWatch.
With iOS 16, you can use the iPhone motion sensor to track your activities. IPhone can pay close attention to steps, distances and third-party exercises to estimate calories burned.
Even if you don't have an AppleWatch, you can set daily activity goals and use the iPhone to track the progress of achieving these goals. The updated fitness application is very useful for users who don't have AppleWatch or other types of activity trackers and want to be more active.
The fitness application looks almost the same as the fitness application available to AppleWatch owners, but it does not include the fitness+tag, because this function is limited to AppleWatch, and there is no standing and exercise ring.
