Hey guys - two main issues with the app for me..
  • several times when doing a session, if I leave the app briefly during a 3 minute rest period say to go into Spotify, the app stops the interval session and basically resets itself.
  • the heart rate connection is absolutely rubbish. It does not in any way reflect the actual heart rate in a constant manner. For example, I got my heart rate to 160 beats per minute, during the rest period I lowered it to 130 beats per minute for say two minutes but in the app, it is still showing the 160.
Hope this helps
