Car maintenance,
measured.
An exact record of every drive, every service, every dollar — for every car you own.

Know what every car will cost you. To the dollar, twelve months out.
Know what your car needs without thinking about it.
Every maintenance item rolls into a single status the moment you open the app. Overdue, coming up, and on-track — sorted by what needs you first.

See the next twelve months, totalled.
Caliper combines service estimates with your actual lease, fuel, insurance, and registration costs into a single mid-estimate. So you know what's coming — and how much to set aside each month to be ready.
Every record, exact to the line.
Service entries, fuel fill-ups, washes, bills. Filter by category, scroll the years. Scan a receipt and Caliper reads the cost, mileage, and parts.
Business and personal, kept apart.
Caliper detects when you start driving and logs the trip in the background — no setup, no pairing. Classify with a swipe, and the year totals itself.

Swap reminders that watch the weather.
Caliper knows which province or state requires winter rubber and when, then reminds you weeks before the deadline — with the shop you used last time saved.
Tax-ready PDFs in two taps.
Caliper exports for CRA, IRS, HMRC, ATO, Revenue Ireland, and IRD. Pick the authority and the period — Caliper does the rest.

Log anything in seconds.
Mileage, fuel, bills, parking, appointments — all one tap from anywhere in the app. No menus to dig through.

And the rest of Pro.
Beyond trips, exports, and the forecast — Pro keeps going.

Before you download.
Is Caliper on the App Store yet?
Not yet — Caliper is currently in beta on TestFlight while the next release is finished. Email support@calipercar.com for an invite. Beta testers get the full app, free.
Do I need a subscription to use Caliper?
No. Caliper is free to download and use for one vehicle, with manual trip logging and the full logbook. Caliper Pro adds automatic trip detection, the CarPlay app, tax-ready mileage exports, multiple vehicles and businesses, the cost forecast, and more.
Is iCloud required?
No. Caliper stores everything on-device by default. If you sign in to iCloud, your data syncs across your iPhone, iPad, and Mac automatically.
Can I export everything if I cancel?
Yes. Your logbook, fuel history, and mileage records export as PDF and CSV from Settings — at any subscription tier, including after you cancel.
What happens to my data if I delete the app?
If you have iCloud sync on, your data stays in your iCloud account and returns when you reinstall. If iCloud is off, deleting the app deletes the data with it — export first.
Which countries does the mileage log support?
Canada (CRA), the United States (IRS), the United Kingdom (HMRC), Australia (ATO), Ireland (Revenue), and New Zealand (IRD).
Does Caliper work without an internet connection?
Yes. Logging, reminders, the logbook, and the car health view all work offline. Sync resumes when you're back online.
Pick how you pay.
Caliper Pro unlocks automatic trip detection, tax-ready mileage exports, and as many vehicles and businesses as you need. Prices apply at the App Store release — the beta is free.
Cancel anytime in Settings.
