A family of four in yukata sitting along the edge of a ryokan veranda, feet over a still mountain lake at sunrise, autumn maples on the far bank and a phone lying face down on the boards beside them.

The trip planner that walks you there.

Plan every day, then hand the phone to anyone. One spoken instruction at a time, Japan's trains routed offline.

What it does

Navology was built for one family's trip to Japan and grew into a planner that treats honesty as a feature: it refuses to guess, it works without signal, and it never phones home.

Japan's railways, offline

Every line, station, and transfer routed on the phone itself. Planned from your sofa, followed in a basement station with no signal. Real track shapes drawn on the map, in each line's own colour.

No network required

Honest by principle

When Navology doesn't know, it says nothing rather than guessing: a dashed line instead of a made-up route, no button instead of the wrong taxi app. You can trust what's on the screen because of what isn't.

Refusal over guessing

Spoken turn-by-turn, anywhere

Walk or drive with voice guidance. Each turn is called twice on the road, and a re-route waits for proof you actually turned wrong. The card holds one instruction, so the person following it never has to choose which part of the screen to read.

Works walking, driving and offline
Live on this page. The countdown and the spoken line are the app's own, running the walk to Sensō-ji.

Worldwide by design

A Texas road trip counts in feet and miles; Tokyo stays in metres like its signs. The taxi button knows the app tourists can actually use in 36 countries.

The whole family, one trip

Share the trip through your own iCloud. Everyone's phone carries the plan, tickets, and check-ins. We run no servers and can't read any of it.

Tickets in your pocket

Scan booking confirmations with the camera and they live inside the day they belong to, readable at the gate, offline.

Start on the web, finish in your pocket

The web planner builds a real Navology trip file: days, stops, meals, trains, notes. Save it, open it on your iPhone, and the app takes over from there: maps, navigation, tickets, and the family sync.
