Great but has a glitch

It currently has a glitch where the 1 RM covers up the buttons where you enter the reps

Does the job!

The app does its job elegantly. It would be nice to go beyond 15 reps.

The latest update set the rep counter behind the 1RM banner and inaccessible. Help, Ross!

Can’t change the reps!!

App worked great until I switched phones(iPhone 6+ to 11) and got the update. The calculated max bar is over the area where you input the reps. Please fix.
