Every car has a story. Most of it is in a shoebox of receipts. cartab keeps the whole record in one place — what you did, what it cost, what parts went in, and what you're planning next. YOUR GARAGE Swipe through your vehicles full-screen, one photo per car. Each one keeps its own color, its own odometer and its own history. THE MAINTENANCE LOG Log an oil change in about fifteen seconds. Title, cost, mileage, done. Add notes, part links, tools and photos when the job deserves it. PROJECTS, NOT JUST REPAIRS A build isn't one line in a log. Give it an estimate, a parts list and a tools list, then track it as it happens — every expense, progress note and milestone on one timeline. Watch what it really cost land against what you thought it would. REMINDERS THAT KNOW YOUR CAR Oil, tires and brakes, by mileage or by time, on intervals you set per vehicle. cartab estimates how far you've driven since the last service, so the reminder arrives before the job is overdue instead of after. A SERVICE RECORD WORTH SHARING Export a color-coded PDF for any vehicle: the full history, parts with links, project timelines, costs and a legend. Hand it to a buyer, a mechanic or an insurer. CSV export too, if you'd rather have the numbers in a spreadsheet. BUILT TO BE KEPT Sign in with Apple and your written record backs up automatically and follows you to a new phone. That's free for everyone — losing six years of records to a dead phone shouldn't be a paid feature. FREE • One vehicle • Unlimited service entries and projects • Unlimited photos, kept on your device • Every reminder • PDF and CSV export • Written records backed up and synced UNLOCK UNLIMITED — $2.99, ONCE • Every vehicle you own • Photo backup to the cloud, at full quality • Family Sharing for up to six people One payment.

Verdict

The call

Rheem EcoNet's advantage is in-app purchases (none vs 1) and ratings volume (16K vs 1). On price, ads, device support and iOS requirement there is nothing between them.
