100% on-device. Bair Cars has no servers, no accounts, and no analytics. The app has no INTERNET permission on Android and no outbound-network entitlement on macOS โ€” it's not that we chose not to send your data, it's that the app cannot. Every car, expense, photo, and reminder lives in a local database. There is nothing for us to see and nothing to sell.

No subscription Track every car you own with no monthly fees or paywalls on your own data.
No ads No ad SDKs, no sponsored content, no behavioral targeting. Zero.
No cloud All data lives in SQLite on your device across iOS, Android, and macOS.
No tracking No analytics, no crash reporters, no usage telemetry of any kind.

Everything a car budget should have

Every Car, Fully Tracked

Make, model, year, VIN, color, fuel type, MPG, purchase price and date, mileage, and a photo. Mark cars active, sold, or archived, and drag-to-reorder your active fleet on the Home screen.

Expenses, Nine Categories

Log fuel, maintenance, repair, insurance, registration & taxes, inspection, warranty, purchase, and financing โ€” each with date, amount, vendor, mileage, notes, and an optional receipt photo.

On-Device Receipt Scanning

Snap a receipt and on-device OCR pre-fills the amount, date, and vendor. You always review and correct before saving โ€” and the photo never leaves your device.

Smart Reminders, Two Ways

Interval-based reminders project a due date from your car's average daily mileage. Expiration-based reminders just flag once a set date, like a registration or insurance card, passes.

Warranties

Track name, provider, expiration date and/or mileage, an attached document photo, and notes for every warranty. Expired ones are flagged visually.

Mileage Logs

Mileage entries over time power your average daily mileage โ€” the number behind accurate reminder due-dates and cost-per-mile figures in Reports.

Reports that actually tell you something

Cost per Mile, Fleet-Wide

A chart comparing cost per mile across every car you own, so you can see at a glance which one is actually cheapest to keep.

Spending by Category

Total spending broken down by fuel, maintenance, insurance, and every other category โ€” across your whole fleet, not just one car.

Per-Car Cost of Ownership

A report tile for each car with total cost of ownership, cost per mile, cost per year, and years owned โ€” the real numbers behind "worth keeping?"

One-Tap Reminder Seeding

Add a new car and seed it instantly with a full set of common maintenance reminders, ready to edit or delete.

Quick-pick templates for every common job

Grouped into four sections, and used both for one-tap car seeding and for adding a reminder yourself.

Your data, your rules

Manual Backup & Restore

Export Backup bundles every table plus every stored photo into a single .zip via the OS share sheet. Restore loads one back in. Nothing syncs automatically โ€” you're always in control of if and when data moves.

Local SQLite Storage

All data lives in a standard SQLite database on your device. No proprietary format, no vendor lock-in, no server involved at any point.

Undo Everywhere

Deleting an expense, reminder, warranty, or car shows an Undo snackbar instead of deleting immediately. Undoing a car restores its full history โ€” expenses, reminders, warranties, and mileage logs, all at once.

Also included: light/dark/system theme, a text-size slider that scales the whole app, and a high-contrast mode for WCAG-friendly color contrast โ€” plus a Wipe All Data option that requires typing "DELETE" to confirm.

Simple, transparent pricing

Every single feature is fully unlocked for all users. The only difference is the number of vehicles you want to track. No subscriptions, ever.

Starter
