Hi Product Hunt! I'm Emil, a solo developer from Bulgaria, and CarStamp is my car log for iPhone, iPad, Mac and Apple Vision Pro, and now Android too.

Why I built it: I bought a used car from its first owner, with every dealership invoice and a stamped service book. I typed it all into a Numbers spreadsheet, line by line with part numbers, and added every new invoice after each visit. But I never tracked fuel, insurance or car washes, so I never really knew what the car cost me, and the insurance policy and registration were never at hand when I needed them. I couldn't find one app that kept all of it in one place the way I wanted, so I built it.

What it does

Fill-ups and charging: gas, diesel, LPG, CNG, hydrogen, EVs and plug-in hybrids, even two fuels in one car
Services line by line, as on the invoice: parts with brand and part number, labor, the shop, or done yourself
Every expense, with recurring costs like insurance or a lease added on their day
Reminders by date or by distance for the maintenance plan and renewals, with Mark Done or Renew right in the notification
Scan a receipt or the odometer with the camera
Insights: spending, cost per mile or km, fuel economy
When you sell: a service history PDF, or the whole history as a file for the buyer

Private by design

No account, no sign-in, no ads, no analytics, no servers. Your data stays on your device and in your own iCloud, and receipts and the odometer are read on the device. On Android, sync goes to your own Google Drive instead. The App Store privacy label says Data Not Collected.

Works in any country

Miles or kilometers, any currency (even several in one car), mpg, L/100 km or kWh/100 km. For cars registered in 30 countries it suggests the usual renewals; elsewhere a general set and your own. In English and Bulgarian.

Pricing

Free for one car, for good: unlimited records, every reminder, import, backup, export and Hand Over, with no ads and no time limit. Pro adds more cars, sync (iCloud on Apple devices, your own Google Drive on Android), detailed insights, unlimited receipt reading, attachments, the PDF and widgets, plus Siri on Apple devices: monthly, yearly with a 14-day free trial, or a one-time Lifetime purchase. If Pro ends, nothing is deleted.

Coming from another app? CarStamp imports your history from other car apps or a CSV file.

I'd love your feedback: what do you track for your car today, and what's missing?
