Build 820500795v4.1.42017-01-23 02:19:36
Coming at you with a new release for the new year, chalk full of juicy bug fixes.
- Fixed an issue where music you select for a specific workout doesn't save, or play, or just plain work at all.
- Workouts that start with a rest period now honor the sacred laws of rests, specifically not playing music if you so please.
- The Activity log now records the actual workout you just completed, instead of always recording the last one you selected.
- Starting right now, the app will once again save the recently selected workout, instead of always switching back to 60-min. We know you love the 60-min workout, but not that much.
Thanks for making Intensity one of the top interval training workouts on the app store!
