Read full description

Just press Start. The timer moves through each step automatically, in the order you set. Set up your steps — like “Warm-up 5 min → Exercise 3 min → Rest 1 min” — and let it run. No interaction needed during the session; it advances to the next step on its own. ■ Runs automatically, step by step Line up what you want to do and press Start. From HIIT and strength training intervals to Pomodoro sessions, morning routines, and bedtime wind-downs — build any sequence you like. ■ No tap needed. Notified when each step ends A notification alerts you at the end of each step. No need to watch the screen or press any button. Leave your phone to the side during workouts or cooking — it keeps running in the background and through screen lock. Use a single step to create a simple one-shot timer that just notifies you when it’s done. ■ Notifies without stopping Even when a notification fires, timing never pauses. Because it measures continuously in the background, accumulated time stays accurate across steps. For anyone who wants every second to land exactly right. ■ Repeats taken care of Set a group to repeat — like “Exercise → Rest” × 10 — and it handles the counting. HIIT, circuits, any set-based routine: build it once, start it with one tap every time. ■ Use it for Exercise (HIIT, strength training, stretching), focus (Pomodoro, studying, deep work, meditation), daily life (morning routine, bedtime wind-down, cooking), and more. ■ Key features - Multi-step sequential timer (works as a single-step timer too) - Group repeats (set the number of sets) - Save, reorder, and edit routines - Notifications for step transitions, countdown, and completion - Sound and vibration settings (silent mode support, test playback) - Per-routine color and icon - Keeps running in the background and through screen lock Make your daily routine more precise, with less effort.
