Strolla: Japanese Walking App

Interval Timer & Voice Coach

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

Japanese walking, coached out loud: 3 minutes brisk, 3 minutes easy, five rounds. Lock your phone, pocket it, keep your music on. Strolla keeps calling the pace. The Japanese walking coach that keeps talking when your iPhone is locked and in your pocket. 3 minutes brisk, 3 minutes easy, five times over — about 30 minutes. At every switch, a calm voice tells you the pace that's starting and your phone buzzes — once for easy, twice for brisk. Screen locked, earbuds in, your own favorite music still playing. No staring at a timer, no unlocking to check. Just walk. THE METHOD Interval Walking Training (IWT) was developed by researchers at Shinshu University in Japan and studied for over 20 years. In a Shinshu University study of adults, five months of interval walking training was associated with improvements in aerobic fitness, leg strength and blood pressure. Strolla guides you through the interval timing researchers used in Japanese walking studies — you decide your own pace. A good rule of thumb: brisk is a pace where talking gets hard; easy is a pace where you get your breath back. WHAT YOU GET, FREE • The standard plan: 5 rounds of 3 minutes brisk and 3 minutes easy • Spoken cues and buzzes at every switch, with the screen locked • A Live Activity on your Lock Screen and in the Dynamic Island, so the current pace and time left are one glance away • Finished walks saved to Apple Health as walking workouts • Your crane companion, which grows from a downy chick into a fully grown crane as your brisk minutes add up • A wetland habitat around it that fills in over time — reeds sprout, the water rises, and it never drains, even after a break • Badges for milestones, and a share card you can send when a walk earns one WALK ANYWHERE Around the block, in the park, at the mall, or on a treadmill — the cues only need your phone. Strolla fits a lunch break and suits every age, from first-time walkers to seniors who want a gentle, structured routine. STROLLA PREMIUM Premium adds three things: • Journey trends — your brisk minutes, week by week, side by side on the Journey tab • Walks on your wrist — start and run your walk from Apple Watch, with a tap on your wrist at every switch • Your own rhythm — start with the standard 5 rounds of 3 + 3, then make it yours: brisk and easy lengths, the number of rounds, an optional warm-up and cool-down Premium is available as a yearly or monthly subscription, or as a one-time purchase. Subscriptions renew automatically until cancelled; cancel anytime in your App Store settings. CALM BY DESIGN • No account, no sign-up • No ads, no tracking — Strolla collects no data • Available in 10 languages Put your phone away and let the crane keep time. Your walk starts with one tap.
