Great for creating a variety of timing options... gym boss is very easy to use and reliable
★★★★★Andreas Mell· Nov 1, 2025
Excellent interval timer, completely customizable. I have been using it for years now, after owning several Gym boss timers.

Absolutely love the Gym Boss app! It’s incredibly intuitive, easy to set up, and perfect for all my interval training needs. Whether I'm doing HIIT, Tabata, or circuit workouts, it just works—flawlessly. The interface is clean, customizable, and reliable every single time. Really impressed with how well it’s designed. Highly recommend it!

I have used this app for years and loved its ease of use, all the different ways to set timers and numbers of intervals...super convenient. THEN last week the timer updated and the countdown will not countdown 3...2...1 like it used to even when I set it to. Can not hear the beeps at all even when I set the volume all the way up in the app. I use this timer when instructing classes and the update makes it totally useless because I have to watch it and count the timer myself. SUPER disappointed.

It was my favorite workout timer. Very easy to set my own workouts. But it has been very glitchy. The music would lose its volume, random crashes, and now it's saying my playlists have no music in them.
