Every free app has ads or is counter intuitive to use. This person built this app from the ground up because they were tired of being unable to have access to something so awesome and simple. I workout more than ever and a huge part of that is how easy this is to use. Seriously—thank you so much for making this! ### 5/5 — Best interval app *2026-02-13* This app is simple and easy to setup and use. I love that they update it, just received the update that the voice command gives you an encouraging half way update! ### 5/5 — Halfway there *2026-02-09* It’s a perfectly simple workout timer. I use it multiple times a week. **Developer response:** Thanks for the feedback. To disable it, open Settings, tap Voice Feedback, and turn off the “Halfway Announcement” option. ### 5/5 — Halfway there *2026-02-06* I love the app, but please remove the infernal “halfway there…” interruption during every set. ### 5/5 — Amazing and Actually Free *2026-01-14* Needed a free app. This app is beautiful, easy, and free. There’s some tweaks that could make things better, but I’ve been using it for yoga and calisthenics for the past week and it’s great! Thanks so much to the developer :) **Developer response:** Thank you very much for the kind review. I am glad to hear you are enjoying the app. I am constantly working on new features and improvements, so stay tuned for updates.

Ustawiasz czas ćwiczeń, czas przerwy, liczby rund – a aplikacja bez litości pilnuje, żebyś nie oszukiwał. Ma nawet przyjemny, motywujący głos, który miło przypomina, że przerwa właśnie się skończyła… i że znowu umrzesz. ### 5/5 — Fajna apka także do jogi. *2025-06-07, version 3.0.2* Fajna apka także do jogi. ### 5/5 — Przydatna do treningów *2025-06-04, version 3.0.2* Prosta,do tabaty i rozciągania. Polecam ### 5/5 — Rewelacja *2025-05-30, version 3.0.2* Rewelacyjna aplikacja. Polecam wszystkim. ## Frequently asked questions about Ares ### What types of workouts can I use Ares for?
