*Important Notice* - Old app, but it can still work perfectly - if given the permissions it needs (see below). It's still being actively used by more than 40,000 people, me, my family & friends included :)
--
This app was built long ago, and I don't plan to update the app in the foreseeable future. It's a free app without trying to make money from it, so I can't afford to maintain it any longer. I do answer emails still.
--
to let the app trigger an alarm while in the background, please go to App Info (long tap on the app) and do the following:
(1) battery optimisation: opt this app out (optimisation OFF)
(2) advanced: Appear on top: turn ON
(3) test it: set timer for 10 seconds, start it and exit the app. If the alarm rings - you're set. If not - there may be variations of the above for your specific phone. Please try allowing other permission that may be relevant.

If you need a Large and simple Countdown Timer, Timesolutely lite is the app for you.
It is a very high quality short Interval Timer and Quick Alarm with very large digits.

The app was designed in particular for these use cases:

- As speakers' timer in presentations, lectures or debate club: The screen won't turn off while you speak.
- Real world timed games with friends, where each player has a time limit to complete a turn.
- To limit children's play or TV time, to allow taking fair turns and to educate about the meaning of time.
- In the kitchen: Very quick and easy to set and start, or pull previous session from history using the Rollback button.
- During exercise: Can run in the background, so you to can enjoy other apps in parallel.
- Taking naps: You can set to wake up at specific time of day, or after a specified time length. There's also a snooze button.
- For taking medication: Just enable the "Replay" button on the alert, and let it alert every 8 hours for example.
- For quick reminders: Set, for example, 1 hour with a 5 minutes early warning.

Limitations: this app does not include stopwatch and cannot measure more than 99 hours. It can run only one session at a time.
