Speed, distance, time, average. And silence.

NNCNC is a bike tracker for people who just want to ride. No feed, no followers, no subscription, no ads — and no server to send your rides to.

WHAT IT DOES

- GPS bike speedometer and trip recorder — keeps recording with the screen off
- Odometer on the home screen, counting every kilometre for each bike
- Service reminders: set your own intervals for chain, brakes and cables, and the odometer turns red when something is overdue
- Ride history: date, distance, time, average and maximum speed, elevation gain, calories
- Your route as a glowing curve on black — no map, no street names, nothing that shows where you live
- Swipe the main number: speed, distance, time or average takes the large slot, whichever you actually watch
- export data and import data: move your whole history to a new phone yourself, in either direction between Android and iPhone

WHY SERVICE INTERVALS MATTER

A bike has no odometer of its own, so almost nobody knows how far a chain has run. A worn chain grinds down the cassette and chainrings with it — replaced on time it is a cheap consumable, missed it costs several times more. This cycling computer counts the kilometres so you do not have to guess.

WHAT IT NEVER DOES

- No account, no email, no password, no profile
- No cloud, no sync, no analytics, no advertising
- No notifications begging you to ride
- No social pressure, no leaderboards

There is no NNCNC server. Not a server we promise not to look at — infrastructure that was never built. Your GPS tracks, rides and bike data stay on the phone because there is physically nowhere else for them to go, and the Data Safety section says no data collected because there is nothing to collect.

Works fully offline. Mobile data is never needed — GPS is enough.

Built by one person who wanted a bike computer, an odometer and quiet. If that is you — welcome.
