Carnest
Service history, oil reminders
Carnest keeps your car's service history. All of it, on your phone, where nothing can take it away: no account to expire, no server to shut down.


What it does, in three screens
Every car log app promises to remember. Carnest has no account to expire and no server to shut down.

Backdate freely
Arrived with a glovebox full of old receipts? Enter them all, in any order.
Write what happened
Service names are free text, not a fixed list. Suggestions appear as you type; ignore them when they are wrong.
DIY counts too
Your own work and a garage visit are the same shape of record.
Printable service book
Hand a complete history to a buyer or a garage (Pro).
Your data stays yours
Your history lives on your device, and in your own private iCloud if you turn it on. No ads, and no tracking across other apps or websites.
- Exchange rates are fetched from a public service, with an offline fallback.
- If you buy Pro, Apple and RevenueCat record the purchase. Neither sees your cars or your receipts.
One car, unlimited service records and unlimited reminders — free, forever. Nothing you write expires or hides behind a counter.
Every car you own, a receipt photo on every record, CSV in and out, a printable service book and cost per 1,000 miles.
