About this app

Easy to use interval timer for Android and Wear OS.
Set the number of series, train time and rest time, with a colorful interface that makes the current state of the timer easy to read at a glance.

Build your own workouts:
- Repeat blocks you can nest to create rounds within rounds
- Custom phases, each with its own name, color, sound and vibration
- Drag and drop to reorder phases and blocks
- Save workouts as presets and reuse them anytime
- Presets sync between your phone and your Wear OS watch

Keep training with the screen off: a colored notification (and Wear ongoing activity) shows the current phase, counts down, and gives you quick pause, stop and skip controls, plus a heads-up alert on each phase change.

Perfect for any of your training activities:
- HIIT Training
- Tabata
- Circuit training
- Pomodoro
...and more.

Seems like one of the best option for a CPR timer for Wear OS 3 at the moment. Simple and seems to do what it says. No extra useless fluff, I like that. I would like to see an infinite repeat (sections) option, the ability to rename the 2 timers and to have it display the current time on the watch app while running. I like the audible and haptic alarms and the 2 timers having different colours. Can't comment yet on battery consumption, will update when I have more info on that.

Olá Christian! Obrigado pela avaliação. Desculpe a demora em responder, mas essa semana estou disponibilizando uma atualização que mostra o relógio durante a execução. Irei trabalhar nas funcionalidades de renomear os cronômetros. Sobre o número de repetições, você pode configurar um número grande de sessões. Dessa forma atenderia sua necessidade?

My only complaint is that on the Galaxy Watch 6 classic, the app does not honor the watch's sound settings and makes the beeping noise when set to vibrate only. It would be nice to be able to navigate back and forth using the spinning bezel. Hope the app stays simple like it is and does not become bloated like other timer apps.
