Good app, would be perfect if it wouldnt freeze so much on my Apple Watch

I like the app. I like the different options it provides to track your workouts and the layout is cool. My biggest issue is the calorie count is waaaay off. I mean I know its not going to perfect and every app is going to have its drawbacks, but it cant be so drastic that on some workouts Im dripping sweat working my butt off and my calorie burn is less than or right at a hundred when Im done and others Im not working as hard and its over 300 hundred calories burned. The discrepancy is huge. Fix that and the freezing issue and it would be 5 star rating for me.
