Odobook is built by one developer with a simple frustration: a car's maintenance record should outlive any app it's kept in. This category is littered with loggers that got abandoned, got acquired, moved to subscriptions, or locked people out of records they spent years building. The record always deserved better than the apps holding it.
You'll own a car for a decade or more. Its service history grows more valuable every year — for warranty claims, for your own sanity, and for the day you sell. So the tool holding that history has to be designed around one uncomfortable question: what happens to your data if the tool disappears?
Odobook's answer is architectural, not contractual. Records live on your device, not our servers. CSV export is free, forever. If Odobook vanished tomorrow, you'd still have everything. We think that's the only honest way to build a log you're meant to keep for fifteen years.
The free tier is genuinely useful — one vehicle, unlimited records, reminders, fuel stats, export — with no ads, ever. If you want more (unlimited vehicles, the PDF service history report, receipt photos, CSV import, custom categories), Pro costs $9.99 once. Not per year. That's the entire model: no VC to satisfy, no data to sell, no meter on your own records. We earn money only when the app is good enough that you choose to pay for it — once.
No account is needed to use Odobook, and the app works fully offline. Signing in is optional and exists solely so a Pro purchase can follow you across devices. Your maintenance data doesn't travel with it — it stays where it belongs.
Odobook is made by Michal Kalous, an independent software developer in the Czech Republic — one person who answers the support email personally. Say hello at hello@odobook.app or start your log at odobook.app/app— it's free.
