Use + Add stage to add activities, which run from top to bottom. Below the divider, Repeats sets how many times the entire list runs: 1–99; 0 repeats until stopped.
Open Completion alert on the timer screen and scroll through four choices: vibration only, short sound only, sound + vibration, or screen only. Watch volume, permissions, silent mode and Do Not Disturb also apply.
Scroll to the bottom of Duration & repeats and tap Save. Scroll down on the timer screen to find Start interval timer. If a permission prompt appears on first use, review it and then start again.

Common questions about settings and connections.
ATLAS Watch Face and ATLAS Tools are separate apps. Install both on the same watch to use intervals and moon details.
The hour hand shows one whole sequence: 30 minutes Focus + 15 minutes Rest = 45 minutes. Three repeats total 135 minutes. Check the current repeat in the app.
Starting an interval switches fills from time progress to timer progress: hour hand = sequence, minute hand = stage. Reset timer progress returns them to normal clock fills.
Buttons are not fixed at the bottom. Scroll down within each screen to find Save, Start or Pause.
Check completion alert mode, notification and alarm/reminder permissions, and watch silent mode, Do Not Disturb and volume. With the screen on, brief system messages announce transitions. Their appearance and duration are controlled by the watch system.
Phase, age, illumination and time to the next full moon are estimates based on an average lunar cycle, not precise astronomy or navigation data.
For compatible round watches with Wear OS 5 or later. Check your watch on Google Play. This Wear OS package does not support Apple Watch or Samsung Tizen watches.
