CarStamp: Car Maintenance Log

CarStamp is a car maintenance log and oil change tracker: gas mileage (MPG), charging, services with their parts and labor, and every car expense, with reminders that keep you ahead of maintenance and renewals. It works in any country, in miles or kilometers and any currency.

It is private by design. No account, no sign-in. No ads, no analytics, no tracking. Your data stays on your phone or tablet, and in your own Google Drive if you turn on sync; we run no servers and can't see it. CarStamp collects no data. Purchases go through Google Play.

LOG IT IN SECONDS
- Fill-ups and charging: gas, diesel, LPG, CNG, hydrogen, electric and plug-in hybrids, two fuels in one car.
- Services line by line, as on the invoice: parts with brand, part number and where you bought them, labor, the shop, or done yourself.
- Every expense, from parking to insurance, and mileage updates.
- Type the mileage straight into a reminder notification.

STAY AHEAD OF THE CAR
- The maintenance plan and renewals (insurance, inspection, registration), with reminders by date or by distance.
- Oil change reminders by miles or by date, and every other item on your maintenance schedule.
- Mark Done or Renew straight from the notification, or snooze it until tomorrow.
- Documents with their expiration dates and reminders.

SEE WHAT IT REALLY COSTS
- Spending, cost per mile or km, and fuel economy at a glance.
- Insights by month and by category, with your biggest expenses.

WORKS IN ANY COUNTRY
- Miles or kilometers; liters, US or imperial gallons, or kWh; mpg (US or UK) or per 100, as in L/100 km and kWh/100 km.
