The Fitbit is one of the most popular fitness trackers out there, and today its companion iOS app was updated with an interesting new feature for iPhone 5s owners. By taking advantage of the new phone’s M7 co-processor (a chip also found in the latest iPads), Fitbit has turned the 5s into a health monitor without the need of an additional wrist strap.

MobileTrack uses the M7 to track the user’s activity throughout the day and distill it into helpful data, like miles traveled and calories burned.

The information you get with just the M7 is obviously not going to be as tailored as what Fitbit’s dedicated hardware can achieve, but it’s a good way to show people how the iPhone can track activity. Nike is doing a similar thing with its Move app, which acts like a gateway drug for the Fuelband. Others are catching on.

The app update also includes redesigned alarms, profile editor, tracker settings, sign-in/sign-out, and more. It’s available for free in the App Store.
