I'm looking for a generic app to use for a variety of different types of workouts. I just need 5 data fields. Workout time, pace, max HR, avg hr, (present) hr zone. I've looked a bunch, but it's guess work and I can't seem to find one that has 5 completely modifiable data fields. I suppose I could make one if I knew how to do that, but I gotta figure one already exists.
