The timer will override each other during supersets. – Gravitus - Workout Tracker Review

This app is extremely well designed and much better than most fitness apps. BUT, when performing supersets, the timer will only keep track of one exercise. Also, when you record down the reps and weight for the second superset exercise, the timer will get overwritten and reset again. It’s quite annoying as I can’t be consistent with how long I have rested.
