I tried to use this app to track how many rounds I was doing in a Crossfit WOD. The app wouldn’t stay active for very long before it would go back the the Apple Watch clock. Each time I finished a round (maybe 1-1.5 minutes later) I had to go back in and find the app, open it, then tap the screen to add my next round. It’s very frustrating to fumble around with the app while you are trying to exercise. Other than this, it would be a great, simple, app.
