## What is Interval Timer?

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" — no mechanical countdown language, just a bit of warmth while you push through.

■ 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

■ 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 — 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

■ 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 — so coming back from the background or a locked screen never leaves the display out of sync.

## Version history (last 5 releases)

### 1.4 — 2026-09-19

• Your own preset name — "Study", "Abs", anything you saved — can now headline the timer screen. Settings › Timer Heading lets you pick whether the preset name or the phase name takes the large text.
• The app is lighter: about 80MB down to about 71MB, with the same 16 tracks at the same quality.

Thank you to the reviewer who asked for the heading change.

### 1.3 — 2026-09-12

• Added nine new tracks to Focus BGM — 16 in all.
• Music now plays straight through instead of stopping after one track.
• Music controls now live on the timer screen: mute the music, switch tracks, skip ahead, and set the volume — all without stopping the timer.

Focus BGM is a Pro feature. Thank you for using the app.

### 1.2 — 2026-08-29

Stability improvements. Thank you for using the app.

### 1.1 — 2026-08-17
