Nagano Walking

An interval walking timer for iPhone, for the Japanese interval walking method developed at Shinshu University in Nagano Prefecture: alternate a few minutes of slow walking with a few minutes of fast walking, and let the app tell you when to switch — through your earbuds, over your podcast, with the phone locked in your pocket.

Common questions

I don't hear the cues.: Cues play at the media volume, not the ringer volume, so turn the volume up while the app is open; the Ring/Silent switch does not affect them. The Walk screen warns you if the media volume is off. Use the ▶ buttons in Settings → Cue sounds to hear every cue right away.
Does it work with the screen locked or while I listen to something else?: Yes. That is the point of the app. Cues briefly lower your music or podcast, play, and let it resume. Pausing the walk releases the audio session; resume from the Walk screen.
What are the lock-screen banners, and can I decline them?: The first time you start a walk, iOS asks whether the app may show notifications. Allowing it adds a silent "Walk fast" / "Walk slow" banner to the lock screen at each pace change. Declining changes nothing else — the sound cues do not depend on it.
How long is the free trial?: 14 days or 10 completed walks (a walk counts once it has run five minutes), whichever comes first. The remaining trial is always shown on the Home screen. After that, starting a walk needs the one-time Lifetime Unlock. The trial record survives deleting and reinstalling the app by design.
I bought the unlock on another iPhone.: Settings → Purchase → Restore Purchases, signed in with the same Apple Account.
Can I change the intervals?: Settings → Intervals: slow and fast each from 1:00 to 10:00 in 30-second steps. Sessions run 15 to 90 minutes. Changes apply to the next walk.
Is there an Apple Watch app?: Not yet. It is the first thing planned after launch. A paired Apple Watch already mirrors the lock-screen banners while the iPhone is locked.
