About
Your car's life in detail.
A mileage log that writes itself. A service record that reads its own receipts. A cost forecast for the year ahead. Not three apps. One record of the car.
KEY FEATURES
- Automatic trip tracking - drives are detected, recorded and logged while your phone stays in your pocket. Mark one as business and it is ready for tax time.
- Mileage logs for your tax return - CRA, IRS, HMRC, Revenue, ATO and IRD formats, exported to PDF with the substantiation each one asks for.
- Car Health at a glance - overdue, coming up, and on track, the moment you open the app.
- Smart reminders - based on how you actually drive, not a fixed calendar.
- Receipt scanning - snap a service receipt and Caliper logs the cost, mileage, and parts. Exact to the line.
- Fuel & MPG tracking - log fill-ups in seconds; see real-world fuel economy over time.
- Bills & cost forecasting - know what your car will cost you next month, next year, and over its lifetime.
- Tire management - seasonal swap reminders, tread depth, install dates and tire ages.
- Widgets & CarPlay - glance at your garage from the Home Screen; trips start tracking when CarPlay connects.
- Car link - plug a Bluetooth OBD2 adapter into the port under the dash and Caliper reads the car itself at the end of every drive: the odometer on most cars from 2019, real fuel economy for that drive, battery and check-engine status in plain words, and the drive played back on a gauge. Reads only. It never writes to the car.
PRIVATE BY DESIGN
No account. No sign-up. No ads. Nothing tied to you.
Your trip routes and locations are stored on your device and are never uploaded. Everything else syncs through your own iCloud, where only you can reach it. When a feature reads something for you, like scanning a receipt, recognising your car from a photo or looking up its specs, only what it needs goes to Anthropic’s Claude through the developer’s server, which keeps nothing. The privacy policy lists each one.
Caliper sends anonymous usage numbers: which versions are in use, how far Caliper drivers go in total, and which makes and models they drive. Never your routes, your VIN, your receipts or anything that identifies you. One switch in Settings › Privacy turns it off.
Car link reads over Bluetooth and keeps what it reads on your phone. If you choose to, Caliper can share which readings your car’s make and model support, to help other owners; it carries no location, no VIN and nothing about you.
There is no profile of you here. Nothing Caliper sends is linked to you, so there is nothing to build one from.

What's New in Caliper
1.7
November 1, 2026
Caliper is here. Your drives log themselves, filed as business or personal, with a mileage log ready for tax time. Service, fuel, bills and receipts sit in one record of your car, with what's due by date and by distance. New in 1.7: a short tour of what Caliper does, a map of gas stations near you, plates and odometer faces to make your car yours, and Spanish for Latin America. A long stop in traffic no longer ends a drive, and winter tires fitted today no longer show as due for summer.
