A standalone Wear OS timer for HIIT, Tabata, AMRAP, EMOM, boxing rounds and plain work/rest intervals. Different haptic cues mark work, rest, the countdown and the finish, so you don't need to look at the screen mid-round. No phone or account needed. A Tile starts your last preset and a complication shows timer status. Free includes the main timers and 1 saved preset; Pro is a one-time purchase for custom circuits and up to 20 presets.
