The alarm does not sound on the intervals ### 1/5 — Yikes *2021-03-15* Can’t listen to music while using the app. ## Most critical reviews (10 lowest-rated) ### 1/5 — I want to love this *2025-11-12* Honestly, I can’t figure out how to use it! ### 1/5 — Timer shuts off if phone goes to sleep *2023-07-25* The timer shuts off when the phone isn’t touched/goes to sleep. What is the point! If I wanted to touch it every thirty seconds I could just use Apple’ built in timer. Pointless ### 1/5 — Worst app ever *2023-06-22* Screen turns off after 30 second. App is useless. ### 1/5 — Meh *2023-06-08, version 1.2.2* Doesn’t even stop the screen from locking. Wow. ### 1/5 — Can’t time longer than 30 sed *2023-05-16, version 1.2.2* If the phone auto locked then the app also stop timing ### 1/5 — Freeze *2023-04-08* The app keeps freezing on me and have to restart it ### 1/5 — Look for a better app *2023-02-08* Not the best app on the market and it's infested with ads. Low quality app. ### 1/5 — Dysfunctional at best *2022-08-05* 1. Either remove your pop up ads or find a way to slip them in without interrupting the workout. Every other time I open this app I am led to a grotesque website advertising something that doesn’t even remotely match my algorithm. No thanks. 2. Stop interrupting the workout. If my phone gets a SINGLE notification, or heaven forbid the screen sleeps to conserve energy, the workout is STOPPED COMPLETELY until you manually go in and restart it. DOES NOT MATTER if you click the lock icon or not. 3. Music is muted by half when this app is open. This is extremely annoying if you listen to music on other apps. Work on your app and do better. ### 1/5 — The timer keeps stopping half way through the HIIT timer *2022-04-18, version 1.2.2* For some reason the timer keeps stopping and I have to stop my workout and keep restarting the timer. I’m using an iPhone 12 Pro ### 1/5 — Minimal effort, UX is terrible *2022-01-02* There isn’t a clear back button when trying to create time intervals, the app flashes and minimizes hen you can see the app’s Home Screen. The voice is robotic and mundane a simple timer sound or boxing bells would have sufficed. Overall this feels like a lazily crafted app. ## Most praised reviews (6 highest-rated) ### 5/5 — Workout timer *2022-10-20* I love this app! Use it for personal workouts and team conditioning. Let’s the music play thru and announces halfway marks on the timer. Great background tool, makes all the difference! ### 5/5 — Highly recommended *2021-03-10* It is much better than the regular timer it tracks the time and tells you with a voice. ### 2/5 — App stops when phone locks *2024-06-10, version 1.2.2* They need to change their app settings so when it is open your phone doesn’t lock and th timers stop - or - when your phone locks the timer keeps going. Fix this it’ll be an excellent app, without it it’s a real pain! ### 2/5 — Totally pointless - Screen turns off after 40 seconds! *2023-03-22* Totally pointless. May as well be using a stop watch because you still have to return to your phone after 40 seconds to make sure it hasn’t switched off! When it switches off it PAUSES the workout! ### 2/5 — Not my favourite *2023-01-29* I have to keep my phone up and it feels cheep ### 2/5 — Lots of bugs/issues *2022-06-21* I gave two stars only because you can adjust your work time, prep time and rest time, and the amount of rounds. That’s the only decent part. Otherwise, it closes out every time you adjust a setting and it freezes when you try to play music. If you start your workout timer and then go to settings to adjust anything, it stops and doesn’t resume, you have to start over entirely. You can’t switch off from the app and still have it working in the background and also can’t turn screen off and have it working . Used once for run/walk intervals and would have enjoyed responding to texts, switching music, etc during my rest periods. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
