## What is Ayumi?

Ayumi brings the Japanese interval walking method (IWT) to iPhone and Apple Watch: 3 minutes fast, 3 minutes slow, repeated 5 times. Based on research from Shinshu University in Japan, this simple protocol has been shown to improve aerobic fitness, leg strength and blood pressure more effectively than walking at a single steady pace.

HANDS-FREE INTERVALS
Your iPhone vibrates and chimes at every phase change. Turn on spoken cues and it names the phase as well, then tells you when the walk is done. Press start and walk.

YOUR WEEK, SUMMED UP
The week closes on Sunday evening and its summary is ready. One page shows how many days you walked, the week's standout walk, how long your heart rate stayed in each zone, the time of day you walk, and the one thing that changed since last week.

YOUR PROGRESS, TRACKED
Every walk is saved automatically. Browse your full history grouped by day, and see a 7-day activity chart, a 6-month trend, your pace split, your daily streak and your weekly goal.

READ YOUR HEART RATE
Walk with a chest strap or your watch and you see the peak of every fast phase, the average of the fast and slow phases, and the time spent in each zone.

BADGES
Road, Rhythm, Horizon and Season measure four different things. They level up as you walk, and they slip back if you stop.

ALSO ON APPLE WATCH
The Apple Watch app runs on its own, so you can leave your phone at home. Live heart rate, a heart-rate zone chart and a post-walk summary.

SAVES TO APPLE HEALTH
Your walks are stored as workouts in Apple Health.

PRIVATE BY DESIGN
No account, no tracking, no ads. Everything stays on your device.

FIRST 7 DAYS FREE
Everything is free for the first 7 days. Cancel before the trial ends and you pay nothing.

Then continue monthly, every 6 months or yearly; the 6-month plan covers the whole five-month journey. If you would rather not subscribe, the one-time lifetime option is still there.

Available in English, Turkish, French, German, Dutch, Italian, Spanish, Portuguese, Swedish, Danish, Norwegian and Finnish.

## Version history (last 5 releases)

### 1.28 — 2026-10-23

Article of the week: a new card on the Journey tab brings our latest Japanese walking article, opened right inside the app. If you like, Ayumi can tell you when a new one is out, at most once a week; you can turn this on or off in Settings.

### 1.27 — 2026-10-20

Small fixes for a calmer app: on the Friends page, badges and rankings now stay in place instead of shuffling, and the Settings page no longer slides sideways while you scroll.

### 1.26 — 2026-10-15

Walk with friends: add a friend with your link or code and see each other's week as stars in the sky, a weekly race and a badge showcase. Only your name, the days you walked and your badges are shared, and only if you turn it on. Gentler reminders now come every other day, around the time you usually walk. Month tabs compare this month and last month with a small leaderboard, and friends who join through your invite get a special price.

### 1.25 — 2026-10-11

New Indoors card: it explains what the treadmill speed does, turns on indoor walking with one tap and shows both speeds. It opens straight from the in-app event.

### 1.24 — 2026-10-07

Ratings are now requested only through Apple's own rating window. The reviews page in the intro and the five-month milestone screen are simpler. Walking on a treadmill? Try the Indoors button on the home screen: it shows the belt speed for each phase.
