The app should clean up its garbage. ### 4/5 — Too touchy but useful *2025-07-10, version 4.2* Too touchy but useful. It gets into so many different modes with just an incidental brush. The lap count has three differing display representations: total time, count minus current lap time or count plus current lap time but to control this it is a screen swipe instead of a settings item. Screen swipes are hard to do while exercising and I want the last representation - it switches unexpectedly by some incidental touch on me. I would like an exercise time period and a rest time period for some exercises - I use IOS stopwatch for those exercises. Maybe the upgraded version has this option? I do find this apt VERY useful though! ### 2/5 — Notifications aren't reliable *2025-01-25, version 4.1* I'll set the timer and sometimes it triggers a notification at the selected intervals, but most of the time it doesn't. Even with my volume switch flipped on and volume turned all the way up, it just refuses to notify me, meaning I have to keep an eye on it the entire time. I can do that with the regular built in stopwatch app. ### 4/5 — Add topic/hint *2025-01-21, version 4.1* It would be nice to have the option, as Apple alarms do, to add a note, to remind you why you set the timer. OK, now it’s time to… do what? ### 3/5 — Used to be my favorite timer *2024-08-23, version 4.1* I used this on my Apple Watch for multiple things. I’m a PE teacher, so it was used a lot. I upgraded and sorry I did. I can’t get either one to show up on my watch face. This is a big deal for me. I feel as though I wasted the $2. While it’s not going to put me in the poor house, I lost something that was very valuable to me as a teaching tool. ### 5/5 — Finally found what I needed *2024-02-23, version 4.1* Super simple. Works perfectly. Wanted repeating timer that does seconds and minutes interval - this does just that. Put phone on silent for haptic only. Please add iPhone capabilities ### 4/5 — Vibrate *2024-01-21, version 4.1* Exactly what I needed, only vibration nothing else ### 5/5 — 좋아요 *2024-01-09* 편리해요 ### 5/5 — Great app!!! *2023-12-23, version 4.1* Great app! This is EXACTLY what I’ve been looking for!!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Very Deceptive *2026-07-16, version 4.6* You’ve paid for the app only to find out you have to pay another $5 to access the features that you just paid $10 for. Total scam. Buyer beware. ### 1/5 — Junk *2026-04-13, version 4.6* Overpriced garbage! ### 1/5 — 사기꾼 *2026-01-28* 결재했는 앱을닫고 두번째 다시 앱을 여니 다시 3300원결재하라고 함 사기꾼이에요 **Developer response:** 고객님, 불편을 드려 죄송합니다. 결제하시면 "주기+"라는 두 번째 앱이 다운로드됩니다. 앱 보관함이나 검색을 통해 찾으실 수 있습니다. 저는 사기꾼이 아니며, 이 앱은 두 가지 버전이 있고, 결제하시면 새로운 앱이 다운로드되는 것입니다. 명확하게 설명드리지 못해 죄송합니다! 구매하신 앱을 잘 사용하시길 바랍니다! ### 1/5 — Zero functionality. Beware *2026-01-04, version 4.6* This app does nothing unless you pay $2 for the “premium” version. Stay away. ### 1/5 — Cancels timer when shaken 😭 *2025-05-30, version 4.1* I want to be able to throw my phone ### 1/5 — Very bad - just a trick to get you to download then charge *2025-03-04, version 4.1* A barebones screen with pop up asking for the paid version - LAME ### 1/5 — Awful. *2024-09-02, version 4.1* Doesn’t have units of measurement. Doesn’t let you do seconds only minutes is a blank interface. Two vertical rows of numbers you scroll through but you don’t know what each one represents. They are just random numbers ### 1/5 — Not working when screen blocked *2024-03-03, version 4.1* Vibration or sound doesn’t work when you go out of the app when tje app is working on the background, and also not working when screen is locked Only working with screen on and during app opened ### 1/5 — Periodic timer *2023-12-14, version 4.1* The beep sound is too low which is unnoticeable, timer is of no use. ### 1/5 — From useful to useless *2023-09-21, version 4.1* Why did they ban the notification when the time is reached? This app becomes useless to me in one night. ## Most praised reviews (10 highest-rated) ### 5/5 — Perfect *2026-07-07, version 4.6* Does exactly what it says. No nonsense, just does one thing really well. Having push notifications is a great addition. ### 5/5 — 素晴らしい *2026-04-17* iPhoneデフォルトアプリのような使いやすさがある。 ### 5/5 — シンプルで使いやすい *2026-02-07* フリー版を使っていますがシンプルで使いやすいです。有償版はプリセットの数が増える、時間単位の設定が可能などの追加機能があるようです。 ### 5/5 — Super aber.. *2026-01-08* Ich hab da mal eine Frage. Ist es möglich ein Timer zu stellen zum Beispiel auf 1 Minute und dann einen zweiten Timer zu stellen auf 15 Sekunden für einePause. So dass ich 1 Minute trainieren kann und 15 Sekunden Pause hab und so weiter. Wenn das in der pro App möglich ist, dann würde ich die kaufen. ### 5/5 — Simple effective timer *2026-01-07, version 4.6* Easy to use and configure ### 5/5 — It’s perfect *2025-06-24, version 4.1* Don’t change it ### 5/5 — Does the job *2025-05-12, version 4.1* Does exactly what I need it for. Thanks gang ### 5/5 — 심플하고 사용하기 편합니다 *2025-01-22* 군더더기 없이 필요한 기능만 들어있어 사용하기 편합니다. 반복 타이머가 필요하신 분, 광고 없고 미끼 구매 옵션 없으니 사용해보세요. 정말 좋습니다 :) ### 5/5 — Love that this runs in the background *2024-03-20, version 4.1* This app is helping me to discover something pretty incredible - but which is only interesting to a very specific type of nerd. I use the app to track the expansion and contraction of the universe, a phenomena which can both be observed by looking at slime mold under microscope, and can also be experienced as a sensation in the body (useful for meditation). That it runs in the background even when the app is closed was a surprise bonus feature, but it has helped me to realize how consistent and exact are the 100 second cycles, and also that there are occasionally stillpoints of exactly 50 seconds. Sorry if this makes no sense, I can’t help it if I’m a nerd. But thank you for making this app available, well worth $2 or more. ### 5/5 — Great app *2024-03-11, version 4.1* This app is incredibly streamlined and easy to use, I love how it gives you exactly what you asked for with nothing random or extra. It was the exact app I was looking for even though me needs were very niche. I do have one annoyance which is even tho my phone is on silent the notifications don't vibrate I am going to look into fixing that but that's it! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
