iPhone
The kind of app that makes you want to take the long way home.
Fumi-log is a walking app that colors in the map wherever you go.
Your commute, a quick errand, a detour on a trip — just carry your phone, and your footsteps gradually become a map that's yours alone.
And when you wander somewhere you don't usually go, who knows what you'll find.
■ The map fills in as you walk
The places you walk are recorded on the map automatically.
There's nothing to learn — install the app and walk like you always do.
■ See how far you've come, in numbers
Coverage stats for your city, your prefecture, your region, and all of Japan.
"How much of my own town have I actually walked?" — you'll know at a glance.
■ Treasures, hidden all over Japan
There are 100 treasures hidden across the country, from famous landmarks to quiet spots only the locals know.
Walk near one and it's yours. Where they're hiding is for you to find out.
■ Your records belong to you alone
- The places you've been are stored only on your device, unless you choose to share them
- You can stop recording whenever you like, and pick it up again anytime
- You can also erase your records later
- No account needed
- Backups are saved to your own iCloud, so they never reach the developer
■ If you are visiting Japan
We ask visitors from abroad whether they would share the record of their stay for tourism research.
If you take part, Fumi-log is free for you. It is entirely optional, and the app works just the same if you decline.
See our privacy policy for details.
■ And there's more
- A trail view of the routes you've walked
- Titles you earn as your coverage grows
- 日本語 / English / 한국어 / 繁體中文 / 简体中文

- You want an excuse to go somewhere you've never been
- You'd like walking to be a habit that lasts
- You want a little something extra on your commute or your errands
- You like keeping the footprints of your trips and drives
- You care less about steps and calories, and more about where you've been
■ Pricing
- Everything is free for the first 14 days after install. No payment details needed
- To keep recording after that, Fumi-log Premium is ¥280/month (tax included)
- The app will let you know before your free period ends — no surprise charges
- Cancel anytime from "Manage subscriptions" in the App Store
- Even after cancelling, you can still view your records, your coverage stats, and your backups, free of charge
■ Walk safely
- Keep your head up and enjoy the streets around you
- Please don't use your phone while walking. Recording is automatic, so there's no need to watch the screen
- Stay out of restricted areas and private property
■ About battery
Tracking your location uses battery.
You can pause recording at any time.
