About

Interval Timer

Read full description

Whether you're settling in to focus or about to move, this is one interval timer for both. Switch between Focus mode and Workout mode with a single tap, and each one greets you with its own timing defaults, color, and wording. In Focus mode the work phase is called "Focus"; in Workout mode it's "Work." Breaks are called "Breathe" and "Long Break" โ€” no mechanical countdown language, just a bit of warmth while you push through. โ–  Who it's for - Anyone using the Pomodoro Technique to focus on study or work - Anyone timing HIIT or Tabata-style workouts - Anyone who needs phase changes to actually reach them while the phone is locked - Anyone tired of timer apps buried in ads โ–  Free features - Pomodoro preset (25 min work / 5 min break, 15 min long break every 4 sets, 8 sets total) - HIIT preset (fully customizable duration and set count) - Custom work time, rest time, and set count - Start, Pause, Reset, Skip - Sound + haptic + notification on every phase change โ€” arrives even when the screen is locked - Save 1 custom preset - Screen stays awake while the timer runs - Session summary screen after the final set - Available in Japanese, English, and Simplified Chinese โ–  Pro features (one-time purchase, no subscription) - Unlimited custom presets - History & Stats (today / this week / all-time focus totals, a 7-day chart, and a session log) - Focus BGM (16 tracks to choose from, continuous play and volume control) - No ads - Restore Purchases supported Timing is calculated from elapsed seconds since start, not a countdown that decrements โ€” so coming back from the background or a locked screen never leaves the display out of sync.
