This is great! The sync across devices was badly needed.
I think another feature that would really make this amazing would be the ability to add your own exercises. An exercise icon editor would be really interesting, but it would work without it just fine.
Genuinely excellent - the sync with Apple Watch is brilliant, it doesn't require to be connected to your phone (great if you leave phone in locker). So many apps miss this.
Easy, quick and encouraging. Great work!
