Hi Product Hunt 👋 I'm Damiano, a solo dev — I build small iPhone apps under Bytamite. "Japanese walking" (three minutes easy, three minutes brisk, repeated) blew up online, but every option I found either needed an Apple Watch or was a generic interval timer. So I built a calm one that coaches the whole walk from your pocket — a soft chime and a quiet voice tell you when to ease off and when to push, and a Live Activity shows the phase on your lock screen. Phone stays away, eyes stay up. A few choices I'm happy with: it runs fully on-device, no account, no backend to babysit, and it's a one-time unlock instead of a subscription (currently $9.99 to launch). The free tier is the full guided walk. Built it solo in a couple of weeks to ride the trend while it's hot. I'd genuinely love to hear what's missing or what you'd change — I read everything. Thanks for taking a look 🙏

Comment highlights

The chimes are subtle and the lock screen phase tracker actually makes it easy to stay in rhythm without looking at the phone. Really like that the full walk is free to try.

Curious how you decide what counts as "brisk" pace without any sensor data from the watch, is it just timed cues or is there some HR or motion data pulled from the phone?

Like the one-time unlock instead of a subscription, that alone makes me more willing to try it. One thing I'm wondering about: if a phone call comes in mid walk and takes over the audio session, does Aruki's interval clock keep running in the background and just resume cueing normally when the call ends, or does the call throw off the timing and you come back to a phase switch you missed?

The lock screen phase indicator is such a smart touch, no need to keep pulling the phone out. Chimes are gentle too, which makes the whole rhythm easy to settle into.

The chime switches without feeling naggy and the lock screen Live Activity is genuinely useful since i usually keep my phone tucked away. Surprised how nicely the pace cues land in your ears without headphones.

Does the voice cue work over AirPods if my phone is in my pocket, or does it only play out of the phone speaker?

How does the app know when to switch between easy and brisk if it’s not using the watch’s heart rate or motion data?

The three-minute interval pacing actually felt sustainable, and I liked that the chime was gentle enough that I did not want to mute it after the first switch.

finally a walking coach that doesn't demand a watch or a subscription, and the lock screen phase indicator is genuinely handy for keeping pace without checking the app.

The Live Activity phase indicator is such a thoughtful touch, letting you actually trust the rhythm without constantly checking the screen. Love that it leans on iPhone-native features instead of pushing you toward a watch.

Took a quick walk with it this morning and the calm chime cues really do make the intervals feel effortless, plus seeing the phase on the lock screen was a nice touch.

Does the voice cue actually adjust if I’m doing the walk on a treadmill or somewhere with steady pace, or is it purely time-based regardless of speed?

Does the chime volume adjust with my iPhone’s silent mode, or do I need to keep the ringer on to actually hear the phase switches?

How does the app know when to switch phases if you're not wearing a watch — is it just a timer, or does it use the motion sensors on the phone in your pocket to detect your pace?

how does the chime work when your phone is on silent or do you have to keep sound on for the cues to actually trigger

the interval chime is softer than i expected and the lock screen phase indicator is genuinely useful. love that it works without making me sign up for anything.

Tried the three minute easy, three minute brisk thing on my lunch walk and the gentle chime switching phases felt way less intrusive than I expected, plus not needing my watch was a nice change.

The brisk/easy interval flow makes walking feel more intentional without turning it into a complicated workout. Voice cues are a nice touch too, since people can just walk instead of checking the screen.

Hi. What’s the biggest benefit of the Japanese walking method compared to regular interval walking?
