iPhone
Your car's whole service history, on your phone. No account, no sign-in, nothing to lose when an app shuts down. Export it whole, any time, for free.
Carnest keeps your car's service history. All of it, on your phone, where nothing can take it away.
Every car log app promises to remember. The reviews of the ones people already use are full of the same sentence: the history is gone. An account expired, a sync went wrong, a company shut the service down. What you are left with is a folder of paper receipts and a year you cannot account for.
Carnest has no account to expire and no server to shut down.
HOW IT WORKS
• Log a service in a few seconds — what was done, when, what it cost, where.
• Backdate freely. Arrived with a glovebox full of old receipts? Enter them all, in any order.
• Photograph the receipt. It is the part you cannot reconstruct from memory later.
• Set what your car is due for, by distance or by time, and get told before it is late.
• Search the whole history for one job: every oil change you have ever paid for, in one tap.
WRITE WHAT ACTUALLY HAPPENED
Service names are free text, not a fixed list you have to squeeze your car into. Suggestions appear as you type; ignore them whenever they are wrong. DIY entries and garage entries are the same shape, because one is not worth less than the other.
YOUR DATA STAYS YOURS
No account. No sign-in. No analytics, no tracking, no third-party SDKs. Your history lives on your device, and — if you turn it on — in your own private iCloud, which is yours and not ours. There is no server here to leak, sell, or switch off.
FREE, NO ASTERISK
One car, unlimited service records and unlimited scheduled reminders — free, forever. Nothing you write ever expires, hides behind a counter, or disappears if you stop paying.
