Karvyn: Car Maintenance

Forget your MOT, oil change or insurance renewal — Karvyn keeps your car ready without accounts, ads or surprises.

WHAT IS KARVYN
A maintenance app and service logbook for car, van, motorhome and classic. One purchase, no subscription. Your data stays on your phone and your own cloud (Google Drive on Android, iCloud on iPhone). Karvyn does not store your vehicle data on our own servers.

WHAT MAKES IT DIFFERENT
✓ Inspection dates estimated for 10 countries (you can always adjust manually): ITV (Spain), MOT (UK), HU (Germany), CT (France), Revisione (Italy), IPO (Portugal), state inspection (US), verificación (Mexico), vistoria (Brazil), VTV (Argentina).
✓ Multi-vehicle from day one: car, van, motorhome, classic, light commercial — each with its own type, fuel, plate, mileage and history.
✓ Service logbook with oil, brakes, tires, filters, seasonal swaps and custom services. Date, mileage, cost, workshop and receipt photo per entry.
✓ Reminders 30/15/7/1 days ahead — local notifications, never push spam.
✓ Google Drive sync — your data, your cloud.
✓ PDF export for resale, workshop visits or insurance claims.
✓ Pay once: one purchase, all your vehicles, all the years.
