Should Apple release the workouts app on the iPhone?

As someone that wrestles daily with wearable tech it got me thinking about how good the Apple Watch workouts app is and wondered if there’s a case to put it on the iPhone without the need to own an Apple Watch. Apps like Strava can track your runs without a watch but I’m not comfortable giving them my data. If Apple could give us a privacy focussed Strava then I’d be into using it.

What do you think?
