Not a bad app. But I put my routine into advanced, completed the workout then got on with my day. Came to do the same thing a couple of days later and the timer had gone. Thought I'd accidentally deleted it, so added all again. Did workout then closed app to check it would still be there for next time and it had deleted again. This is frustrating. It does say you can have 1 or 2 advanced timers, so why does it do this? Is it to inadvertently 'persuade' people to pay....

You can save unlimited timers with up to 2 exercises (e.g. a simple timer). If you want to save timers with more exercises you can purchase the pro version. You can create and run an advanced timer to test it. But if you don't save it (click on the 💾 button), the timer is lost if you or the system closes the app.

+ Pretty easy to use, and can put together however timers you need. Generally does what a timer should do. - The voice that says the exercise name is so quiet compared to the beep of the timer that it is impossible to hear. There is only one audio volume setting so you can't balance the two. - when you start a specific timer, 70% of the time it starts a different timer which is very frustrating. Edit: There are no volume controls in text-to-speech device settings, only speech rate and pitch

Hi Marcus, the timer uses the default text-to-speech engine of your device. In the app it is already set to the max. volume. But you can increase the volume in your device settings. Select Accessibility > Text-to-speech output > Click on the icon next to preferred engine > increase volume. Reg. other prob.: send me an email developer.mdev@gmail.com

Very pleased with the app. Nice simple layout and the colored backgrounds are a nice touch. Having used it for a week and added timers its also very easy to create and edit timers. The UI is clear and easy to navigate. Initially gave it 4 stars but thinking about the fact that no data is shared I have to give it 5 stars! If possible it would be good to saved timers in categories such as cooking, workouts or work. Or categorization by colour. Would love to see a WearOS version of this app.

Hi J Play, thank you very much for your review and the 5 stars :) I'm glad you like the app. Categories for timers is actually a feature I have planned for the next release. WearOS: Maybe sometime in the future ;) Best regards Matthias
