When I need it, I open and use it. ### 4/5 — Missing one feature I would love to see *2026-03-30, version 4.3.3* This is almost everything I needed! The one thing I'd really like to see is just a button to be able to skip to the next exercise. There are times when my set gets interrupted and I would like to skip to the middle of the routine, but as it stands I either need to wait for the timer to reach that point, or create a new timer JUST for this specific circumstance. Just a little annoying. ### 4/5 — Mostly Great *2025-06-07, version 4.3.3* Excellent app for a great price. Worked wonderfully on iPhone. Unfortunately, when used on the watch the timer stops counting down when the screen goes into sleep. ### 4/5 — works great! Stops at phone ring n youtube *2025-05-05, version 4.3.3* I find this works great. But have some wishes. The app will stop / pause workout if you get a phone call. Even if you don’t answer. Similarly stops w youtube or video play. If it stops and you un pause it will not complete work out. So there is no record of you doing the workout even partial. No transfer of data to health app. Wish away to duplicate work out to make adjustments eg longer or shorter workouts w or wo warm up. ### 4/5 — Please Update!!!!! *2025-04-30, version 4.3.3* Hi. Is there a way to pick exact work and rest times for custom timers? I have the paid version, but am frustrated that I can’t choose exactly how long the timer periods last. For doing specific breathwork and certain drills, I need to be able to work in 6,7, or 8 second intervals for example, not just 5 or 10. Is there something I’m missing, or could we please get an update to allow for this? Would make the app and service infinitely better for all and useable for me. ### 2/5 — Time *2025-04-24, version 4.3.3* It’s stuck on military time ### 5/5 — Favorite timer so far *2025-03-24, version 4.3.3* I’ve downloaded and tried so many timers and this one is by far my favorite. Nothing fancy or complicated just a simple timer. Works great with the free version and I will buy the lifetime version for sure. Most other “free timers” make it so annoying to use that I delete almost instantly. ### 2/5 — Limited to three timers ever *2025-03-02, version 4.3.3* I had 3, made a 4th. Wont unlock that timer til upgraded. Deleted other timer, back to 3. Still can't use new timer. App apparently limited to three timers ever on free version ### 5/5 — La Mejor *2025-03-01, version 4.3.3* Exelente aplicación. Muchas gracias al desarrollador por su gran trabajo. ### 3/5 — Kostenfrei *2025-01-18, version 4.3.3* Ich nutze die kostenfreie Version der App. Diese kann ich gut nutzen. Verschiedene Programme abspeichern wäre super. Einzig der immer wieder kehrende Hinweis auf die bezahlbare Version stört ein wenig. ### 2/5 — App Stops Timer When I Leave the App *2025-01-12, version 4.3.3* A lot of times when I leave the app, the timer will occasionally stop counting down, so it messes up my entire workout. I like the app otherwise but this is a really annoying bug :( ## Most critical reviews (10 lowest-rated) ### 1/5 — Paid for lifetime still does not work, asks to subscribe again. *2026-07-15, version 4.3.3* Paid for lifetime still does not work, asks to subscribe again. ### 1/5 — What happened to the ffw and repeat buttons? *2026-07-13, version 4.3.3* Can’t fast forward anymore so the app is basically useless to me now. ### 1/5 — Can’t use without paying? *2026-05-08, version 4.3.3* I spent 20 minutes configuring a timer. When I go to use, it will not let me continue without paying. I don’t mind paying for useful apps, but I wanted to try it out first. I didn’t see any info that indicated payment would be required before trying. ### 1/5 — Not worth setting up *2025-11-07, version 4.3.3* Spent a good bit of time setting up one routine for stretching, just playing around with routine and figuring out how the app works. then on my second test of the routine, because I made some mistakes, bam there’s a pay wall. Can’t move forward, can’t finish the routine. Close app and open again, delete the default thing they setup assuming I had more than is allowed for the free service. Nope still pay wall. This is hardly worth the time to set up if this is how the app works. Learn from my experience, find something better unless you want to pay for the bare minimum. ### 1/5 — Sound doesn’t work *2025-10-08, version 4.3.3* Don’t bother buying this app if you want sound. It doesn’t work. I’ve checked all the settings and emailed customer support but have not gotten a response. ### 1/5 — Scammers *2025-07-27, version 4.3.3* They offered a free 7day pro trial and charged me for a year. Haven’t been refunded ### 1/5 — Now completely useless *2025-03-31, version 4.3.3* Now doesn’t work as the developers insist on only making money out of it. Bye bye. ### 1/5 — Beware! I Purchased lifetime but can’t access features *2025-02-05, version 4.3.3* NO RESPONSE FROM APP SUPPORT. Otherwise this app would be fantastic. That’s a big otherwise… ### 1/5 — Marginal at best *2025-02-01, version 4.3.3* I guess I expected more because I paid for the app. I also heard good things about it, but what I don’t like is that I was not able to listen to my music while the timer was going. I don’t like that it did not transfer to my Apple Watch exactly as it is in the phone. It is the most basic timers and I use it for my CrossFit workout exclusive. I would not purchase again. ### 1/5 — Misleading *2024-10-15, version 4.3.3* I could only make one unique timer (I wanted to make multiple timers to use for a workout with multiple different timer lengths). In this app, you can only make 1 unique timer before being blocked by a paywall. ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2026-08-25, version 4.3.3* Very customisable, great value for money. Been using it for years 👌👌 ### 5/5 — Just the Best *2026-08-11, version 4.3.3* It’s the best interval timer ever. Just get it. ### 5/5 — It’s all you need. *2026-07-05, version 4.3.3* Simple, perfect. It’s all you need. ### 5/5 — Very good, one or two flaws *2026-06-23, version 4.3.3* Most interval apps are incredibly clunky. The interface for this app is very smooth, once you take a couple minutes to learn it — the interface is pretty intuitive, but it won’t hold your hand if you’re having trouble figuring it out. More importantly, after updating this morning, the app isn’t reliably making sounds anymore! I hope they catch this and patch it. ### 5/5 — Pretty great *2026-06-18, version 4.3.3* I’ve had this app for quite some time only thing I wish they’d add is individual seconds not just hoping 5-10-15 and after some numbers it skips too much it’d be nice to just type the time needed and for it to go off of that ### 5/5 — Perfect for what it is *2026-03-16, version 4.3.3* Free version offers exactly what I needed. Free version has pop up asking for subscription but it’s reasonable. Highly recommend! ### 5/5 — Für meine Zwecke, perfekt! *2026-02-14* Auf der Suche nach einem einfachen Programm für Intervalltraining bin ich hier hängen geblieben, ohne versteckte Abofalle, ohne Schnickschnack. Ich mache Übungen mit dem Swing Stick, 40 Sekunden Übung, 20 Sekunden Pause, und so weiter das Ganze in fünf verschiedenen Übungen. Kein umständliches Einstellen oder suche in Menüs, einfach wunderbar. ### 5/5 — How much is the limit for workouts *2025-07-16, version 4.3.3* How much ### 5/5 — vibration alarm pls *2025-06-03* If you add that feature, I’ll buy it right away. ### 5/5 — Solid App *2025-04-28, version 4.3.3* Pretty good except for the ads for premium --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
