Frequently asked questions

The timer stops when I lock the screen or switch apps

xTimer keeps running in the background so that interval cues and the BPM metronome keep sounding. If sound stops, check that the app has permission to play audio and that Silent Mode / Focus modes are not muting it. On Android, make sure battery optimization is not restricting xTimer.

I bought “Remove Ads” but still see ads

Open Settings in the app and tap Restore purchases. If ads still appear, email us with the receipt from the App Store or Google Play.

How do I delete my data?

xTimer stores your settings and history only on your device. Deleting the app removes all of it. See the Privacy Policy for details.
