In Settings > Focus timer alerts, you can set the sound alerts and vibration alerts. You can select different alerts for the following scenarios:
To test your notification alerts before starting a timer, go to Settings > Focus timer alerts and select on the button beside each alert scenario. This will give you a preview of how your alert will sound/feel like.
On some android devices (Huawei, Xiaomi, etc.), the Android OS stops Focusmeter when it is running in the background. Since Focusmeter is stopped, it is not able to send notification alerts when the timer is up. Please visit https://dontkillmyapp.com/ for more details.
A possible solution would be to exclude Focusmeter from your phoneβs battery optimization list. By excluding Focusmeter from battery optimization, it may prevent Focusmeter from being stopped in the background. In Focusmeter, please go to Settings > Ignore Battery Optimization for instructions on how to do this.
