It is early for a full review, but two annoyances. First up I set some music on my iPhone, I start the timer app and at the first interval change the voice over comes on but stops the music. Stop workout - swap to music and restart - swap to timer and unpause to recommence workout, losing focus. Second was that as I counted down the 2 intervals remaining stopped at the end of interval 9 ( set as 10 working intervals) now I want to check if this either only 9 intervals or 10 intervals but the remains count is out by 1. There is no method, that I can see, to include a set warmup interval, I use a 2 min warmup before the session which I would prefer to time in the same app. ### 4/5 — FONCEZ✨ *2022-04-09* Alors tout d’abord c’est une très bonne application, gratuite (aucun mode payement, sans pub, c’est vraiment tout benef)😁 On peut créer ses propres exercices✨ J’aimerais que les exercices, après les avoir créés et quand on veut faire du sport, s’enclenchent automatiquement les uns à la suite des autres car c’est pénible de devoir à chaque fois aller dans les exercices pour activer le prochain. Voilà sinon bravo aux développeurs, bonne soirée ✨🌞 Édit : je viens de découvrir qu’il y a aussi un mode de personnalisation de sonnerie, de couleurs et de compteurs dans les réglages😁 Vraiment cette app vaut le coup✨ ### 5/5 — シンプルで使いやすい *2025-06-14* おかげさまで体幹トレーニングが続いてます♪ ### 5/5 — セット数のカウントアップができたら良い *2024-06-22* 機能がとてもシンプルで使いやすく、操作性も良いです。1ラウンド3分インターバル30秒、1ラウンド1分インターバル30秒など格闘技のスパーリングで使っています。いくつものプリセットを記録できるのが良いです。 またタバタ式も最初からセットしてあるので便利です。 1つだけ要望があるとしたら、セット数がカウントダウン式でしか数えられないことです。今何ラウンド目なのかを一目でわかるカウントアップ式にも切り替えれたら最高に良いです。 ### 5/5 — シンプルで使いやすい *2023-12-21* ワークアウト　休憩　セット数 を簡単に変更できるので使いやすい。 ### 5/5 — Amazing 👍 :) *2023-08-03* Loud timer to signify when to rest and the end of a workout Overall really good :) ### 5/5 — Simple and effective *2023-06-25, version 1.3.1* I use this app to stretch before running. It gives me voice alerts which means I don’t need to be watching the clock. ### 5/5 — Great app!!! *2023-06-04, version 1.3.0* Easy to use!!! Exactly what I’m looking for <3. The app would be 100% times better if it announces the upcoming exercise name. That way I know what is coming up next ### 5/5 — AMAZING *2021-12-31, version 1.3.0* Idk about u but I’m wanna be like #girlboss and take care of my body and Oml is tf this is mwa I live this app and tbh it the only one that works well you can customize everything and you can make more than one work out timer ## Most praised reviews (3 highest-rated) ### 5/5 — Thank you! *2021-05-25, version 1.3.0* Update: Thanks for implementing the suggestions, that’s awesome. Upgraded already. One last suggestion: It would be great to be able to toggle whether the screen should stay on or not. I mostly go by sound and it would preserve the OLED. Love the app, all I wish I could do was to change the tunes for the finish timer to something slightly more decent than a Brain alarms clock. Would also be happy to pay to remove the ads. Otherwise it is simple, clean and does everything I need. Good job and thanks! ### 5/5 — 使いやすい❗️ *2021-03-19* 毎日のトレーニング、ルーティンワーク、勉強などそれぞれ登録出来て、シンプルで使いやすい。これのお陰で毎朝のシンプル体操続いてます♬ ### 5/5 — シンプル *2020-10-21* ワークアウトする時はシンプルな方がいいので使いやすいです。 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
