First things first: Thanks a lot for creating this app. I hope you will continue your development!
What I love about the app right from the start, it is easy to use and no cloud and it perfectly does what I was looking for, in addition to the 2 mentioned:
- Usage of my chest strap
- audio signal when out of zone
- No watch necessary
What I liked during usage:
- repeated audio signal if still out of zone
What I noticed during running, and previoudly had not been looking for:
- different sound when getting back in the zone
- volume control, sound was a bit too low for me. I'm listening to music during running and in comparisson, it could use some more power
- zone control w/o any timelimit. e.g Endurance - giving me a timelimit puts me under pressure ;-)
Some nice to have in the future:
- record bpm and gps for export or usage with open street map.
