Was a great App
Was a great App when I first started using it on my iPad. However, I have been disappointed since the buzzer notification that indicates a change in exercise or Set no longer works. I have been unable to triage the problem to store the buzzer sound. Until this is rectified I would not recommend this App, which is a shame as it was really good before this occured.
App no longer works in background on current iOS
The point of the app was to be able to train with the timer app running in the background while other apps are also in use - this is no longer happening. In fact, it does not even work in Lock Screen mode anymore. Please fix ASAP.
Latest update no sound
I’ve been using GymBoss for 10 years, back when it was a physical device even. Updated on its own last night and it only does the 3 second warning countdown 50% of the time, not useful when doing tabata training and need it every day. I’ll be looking elsewhere.
I use it everyday
The app doesnt work anymore with latest ios. It just does not open at all. I need it everyday. Can you please fix this ?
Not supported with lasted iOS update
I love this app, but I recently updated my phone to the newest iOS and my Gym Boss app will not open. It force closes. I’ve tried deleting and re-downloading the app. I’ve tried turning my phone on and off again and nothing works which is a shame because I use this app a lot.
Great app... but...
Super app, love it for Hiit workouts. Just wish I could use this app on my Apple Watch! It would simplify my workout to be able to peek at my watch!
Too unreliable
App is glitchy. Ads appear and stop the timer. Sounds sometimes don’t play. Tired of stopping my run to redo settings—looking for a new interval app.
GymBoss Timer
A great timer but impossible to get any alarm sounds to work except the GymBoss alarm. Volume is not loud enough to hear over the quietest music!!
Great app
The only complaint I have is no support for Apple Watch. Would be nice to just have to glance at my watch during a workout.
Awesome in a clinical setting!
I use the Gym Boss App in a clinical setting for timing various intervals during different protocols, and I couldn’t be happier with it 😀
