### 5/5 — Love GymBoss!

*2026-08-18, version 4.0.10*

I love that you can set up so many different kinds of timers and the app will save them all!

### 4/5 — Great! But

*2026-07-31, version 4.0.10*

This is a great timing app but I wish it stayed on the screen and didn’t turn off cause I had to keep checking the time. Still does its job👍

### 1/5 — worst app

*2026-07-31, version 4.0.10*

there is no directions on how to use this app. There is no demonstrations on how to use this app. In this app is very outdated. It is very old and has not been updated in years. I have quite a few apps on my phone and this is the only app that I have that I don’t know how to use. And the only reason why I don’t know how to use this is because of its poor design.

### 5/5 — TABATA WORKOUT TIMER

*2026-07-23, version 4.0.10*

This is a great tool! I have started the Tabata weight training and doing the timing on my phone was not effective. I had to set the timer a few seconds more to be able to do the 20 seconds work. This is a great tool! I will share this with friends! Many blessings, José retired Sergeant Major USMC

### 5/5 — Great app for intervals!

*2026-03-24, version 4.0.6*
