Service timeline
Log a service in seconds: date, odometer, category, cost, notes, and who did the work. DIY or shop, everything lands on one chronological timeline per vehicle, so “when did I last change the coolant?” takes three seconds to answer, not a dig through the glovebox.

Reminders
Maintenance is due by distance, but calendars only speak in dates — the exact reason spreadsheet logs quietly fail. Odobook reminders track both: set “every 5,000 miles or 6 months,” and the app estimates what's coming from the mileage you already log.

A documented service history can add roughly 10–20% to a used car's value, and in a Kwik Fit survey of 2,000 owners nearly half said they wouldn't consider a used car without one. But oil changes done in your driveway never appear in any commercial history report. Odobook Pro turns your log into a clean, dated, odometer-stamped PDF — proof a buyer can actually hold.

Why not a subscription?
This category has burned its users, repeatedly. Apps that were free for a decade introduced paid tiers. Annual prices that started around $6 have been raised to $25 and beyond. One popular logger retroactively limited a paid “lifetime” ad-free unlock to two years, then pushed everyone to a subscription. Others simply stopped shipping updates — years ago — while still charging, leaving people locked out of records they spent years building.
We think that's backwards. A car outlives app trends: you'll own it for a decade, and the log only becomes more valuable with every entry. A tool like that has to be built so that you can walk away and lose nothing — which is exactly why Odobook is local-first with free CSV export, and why Pro is a one-time $9.99 purchase instead of a meter running on your own records.

FAQ
Yes. The free tier includes one vehicle, unlimited service records, unlimited reminders, fuel tracking with consumption stats, and CSV export — with no ads and no account required. Pro is a single $9.99 purchase that adds unlimited vehicles, the PDF service history report, receipt photos, CSV import, and custom categories.
On your device, in a local database. Odobook is local-first: records never need to touch a server, and the app works fully offline. You can export everything to CSV at any time, for free. Signing in is optional and only used to attach your Pro purchase to you so it follows you across devices.
Nothing. Your data lives on your device, not on our servers, and CSV export is free forever — so you always hold a complete, portable copy of your service history. That is the whole point of building local-first.
Really one-time. Pro is a standard one-time purchase (a non-consumable on the app stores), not a subscription — everything Pro includes today is yours for good. If we ever add features with real recurring server costs, such as optional cloud sync, those would be priced separately and honestly. Pro itself never turns into a subscription.
Yes — Pro includes CSV import, so you can bring records over from a Google Sheets or Excel maintenance log, or from CSV exports of apps like Drivvo, Fuelio, Fuelly, aCar, or Simply Auto, and keep your full history in one place.
Yes. Because all data is stored locally, logging a service, a fill-up, or checking a reminder works with no connection at all — in an underground garage or at a gas pump with no signal.
The web app runs in any modern browser at odobook.app and is free to use with no install. Native Android and iOS apps are on the way — the same log, the same one-time Pro purchase.
The best day to start a maintenance log was the day you bought the car. The second best is today — it takes about a minute.
