A logbook, not a game.

A small, independent iPhone app for people who love their cars and the roads.

Named for the old roads.

A kaidō is one of Japan's old highways. The most famous, the Tōkaidō, ran from Edo to Kyoto through fifty-three post stations, and travelers kept track of every one.

Kaido does the same for your car. Every drive is a stage, every new town a station, and the map is the record of the road you've traveled together.

The O in the name is a wheel cut in three. It's also the app's icon.

What Kaido won't do.

Rank you on speed.
Friends compare new roads, new counties and the longest trip. Nobody wins by driving fastest.
Make you sign up.
There's no Kaido account. Your drives sync through your own iCloud, and there's no password to forget.
Lock up your own drives.
Recording, your map and the Atlas stay free. Your trips are never held behind a paywall.
Track you for ads.
Kaido has no ads and no analytics trackers, and it never sells data or shares it with insurers.
