It seems like this app is currently heavy in features for running/cycling but lacks features for other types of exercise. Unless I'm missing something. When setting up the "workouts", you're limited in scope. I'm not talking a full blown set/rep exercise tracker (there are apps for that), but rather a basic workout tracker.
It'd be nice to be able to start a workout (such as circuit training) and have it track the duration / max HR / time in HR zones / avg. HR and also prompt you for a set total. This would benefit Crossfitters and athletes looking to track progress with one app.
