Steerlog is the car maintenance log you'll still have in 15 years. Log any service, fill-up, or expense in seconds — and always know what's due next. No account. No ads. No subscription. No company server that can lose your records: everything lives on your phone and syncs privately through your own iCloud. Track every car you own, get reminded before the next oil change, and see what your car really costs. WHY DRIVERS SWITCH TO STEERLOG • Your data is actually yours — stored on-device, synced to YOUR iCloud, never to our servers. Nothing to lose when an app shuts down. • Buy once, own forever — a single one-time unlock for every extra car. No subscription, ever.

Your history is portable on day one. EVERYTHING A CAR LOG SHOULD DO • Log service, fuel, and expenses in seconds — odometer, cost, notes, receipts • Service reminders by date AND mileage — "oil change in 800 mi" on your lock screen • Home-screen widget with a live countdown to your next service • Fuel economy (MPG or L/100km) calculated automatically from your fill-ups • Charts: monthly spend, cost per mile, fuel economy over time (Pro adds Insights: forecasts & breakdowns) • Full history with search and filters — 15 years from now, it's all still there • Bring your history with you — import a CSV from another app or a spreadsheet, even when its dates were wiped: SteerLog places each service by odometer • Notes on every car — the shop that knows it, quirks, the part to buy next • Miles or kilometers, any currency FREE VS PRO Free: one vehicle with every feature above — full history, reminders, widget, charts, iCloud sync, backup, CSV/PDF export. Pro (one one-time purchase): unlimited vehicles, Insights (cost forecasts, year-over-year, spending breakdown), photo receipts, PDFs and documents in the glovebox, and maintenance schedule presets. That's the whole price list. Built by one person who was tired of car apps that lose people's records. Support: support@steerlog.app
