I think it should be included in the top 5 workout timers. ## Most critical reviews (10 lowest-rated) ### 1/5 — Can't set up sets have to do it daily *2020-04-04, version 2.7.1* Can't make your own sets up at it doesn't let you do annoying 😡 ### 1/5 — Crashes. Can’t use. *2019-09-27, version 1.2.2* Can’t run a single interval. Crashes as soon as I start the interval set. ### 3/5 — Good app for basic Intervals *2024-08-07, version 3.7.1* I like using this app. It’s pretty easy for basic intervals. You can only have one custom one for a free account. I wish there were a little more of an option, but it is what it is for free. ### 3/5 — Great interface and functionality but... *2019-08-08, version 1.2.1* I love everything this app does, the look and functions are perfect. But for me it has one fatal flaw, it will not send the interval change tone to my Bluetooth headphones when the phone is locked. It does work fine when locked and using the wired headphones or no headphones, but not on Bluetooth :( ### 4/5 — Swing *2026-05-04, version 3.7.8* Very good ### 4/5 — Beginner to Working Out *2025-01-17, version 3.7.3* Love it! Simple to use. ### 4/5 — Great timer *2024-07-03, version 3.7.1* Except for the ads. But it’s free, so I tolerate it… ### 4/5 — Bug: interval set index incorrect [resolved] *2023-09-11, version 3.3.9* When you have started an interval, the UX always shows “1/1” even if it’s set 3 of 10 for example. Please let me know when this bug is fixed and I will update review score. [Update] Very quick developer response. Not a bug, this is the UX design working as expected, it was an issue caused by my own misunderstanding. I didn’t understand how events and combinations were supposed to be used. Thank you for the explanation. ### 4/5 — Simple yet powerful *2021-06-04, version 3.3.7* I use the app to plan my interval running. Easy to use,highly customisable, and affordable. Happy to recommend. ### 5/5 — Well designed, easy to use, reads instructions and operates in background. *2026-06-28, version 3.7.8* I was actually looking for an app that would read instructions, so that I can schedule activities in a way that works for my ADHD. I will say that it does that better than any other app I have found, as well as having powerful overall functionality. For example any set that you create you can also add to a larger ‘combination’ which can add together various sets you’ve created. Very nice app, I bought the full version, just to be able to set daily reminders to use it. ## Most praised reviews (9 highest-rated) ### 5/5 — Exactly what I needed *2026-05-14, version 3.7.8* Using the free version and it does everything I need and with smart usage of timings and rest periods I was able to construct every scenario I needed. ### 5/5 — Great app *2026-05-02, version 3.7.8* I use this for interval runs, HIIT workouts, breaks, cleaning, EVERYTHING.
