TestFlight makes it easy to test beta versions of macOS apps, then provide valuable feedback to developers before they release their apps on the App Store. Developers invite testers through email or a public link.

When you test a beta app, Apple collects and sends crash logs, usage information and any feedback you submit to the developer. The developer may use this information to improve their app and related products. Apple may use crash logs and usage information to improve our products and services.

Simply the best

Just the best app on the App Store. I was a little worried there for a bit, but once I had it downloaded and installed all I can say it that’s it’s a stunning app and user experience.

What an easy to use and simple application, makes it easier for apps to get better quicker.

The sync is not done all the time. This should happen regardless of starting the exercise on the phone or the watch app.
Lastly I need it needs to be included in the list on current running apps so that I could easily go to it.
