Common questions

I don't hear the cues when the phone is locked

Turn the media volume up (the cues play as media, so on iPhone they also play with the silent switch on). Each cue has its own volume under the timer's Sounds; the master volume is at the top of that screen.

The timer isn't on the lock screen

Allow notifications for Roll Timer in the system Settings. On iPhone also check Settings → Roll Timer → Live Activities. The timer keeps running without them; you just won't see it on the lock screen.

Android: the timer stops when the screen is off

Some phones close background apps aggressively. Open Settings → Apps → Roll Timer → Battery and choose Unrestricted. Roll Timer only runs in the background while a workout is active.

How do I change just one round?

Open the timer's settings and switch to Custom. Tap any round or rest to change it; filled blocks are the ones you changed.

How do I keep the screen on?

Home → settings (sliders icon) → Keep screen on, Bright screen and Brightness.

Can I get a timer back after deleting it?

Tap Undo within a few seconds. After that it is gone; the ready timers come back only when every timer is deleted.

How do I use Roll Timer on my watch?

Apple Watch: the watch app comes with the iPhone app; if it isn't on your watch, open the Watch app on your iPhone and install Roll Timer from the list of available apps. Wear OS: install Roll Timer from Google Play on the watch; it works with Roll Timer from Google Play on your phone. Start a timer on the watch or on the phone: the phone plays the cues, the watch shows the timer and lets you pause, skip or end it.
