## Most critical reviews (5 lowest-rated)

### 1/5 — Fix

*2020-11-09, version 1.1.1*

Can’t change the reps the blue thing is in the way fix that then this app works perfectly

### 1/5 — Only for Americans

*2019-02-06*

Minutia. You can't even change it to the Metric system. It still uses that archaic imperial system. Also it has ads on it for one of the most basic settings I have ever seen. Load of tosh.
There are much better ones out there that allow you to change from lbs to KG!

### 2/5 — Can’t change the reps!!

*2020-01-23, version 1.1.1*

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.

### 4/5 — Great but has a glitch

*2019-06-20, version 1.1.1*

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

### 5/5 — Does the job!

*2018-03-05, version 1.1.1*

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!
