Try one calendar track day with multiple runs and sessions on that date. When you need another car or another track day, Tenths Unlimited unlocks unlimited cars and track days with one purchase. No subscription. Your saved records remain readable, editable and exportable. BUILD LEDGER Record modifications, suppliers, part numbers, dates and costs. See what you have spent on each car.

LIVE LAP TIMER Set a start/finish line and use on-device GPS to record laps and sector splits while Tenths is open on screen. GPS accuracy depends on the device and conditions. CIRCUIT PASSPORT Explore the circuit catalogue, record visits and follow your personal bests. UK VEHICLE LOOKUP Look up official DVSA MOT history using a registration, including recorded mileage, results and advisories. Network access is required for lookups. MAINTENANCE AND DOCUMENTS Keep service history, reminders, receipts and ownership documents together. SHARE AND BACK UP Create build-reveal and Season Wrapped cards. Export your data and make backups to files you control. PRIVATE BY DESIGN Your garage, logbook, media and recorded lap traces stay on your device. There is no Tenths account, advertising or analytics SDK. Optional vehicle lookups contact the Tenths lookup service; maps contact the platform map provider. Apple processes purchases and restores. Tenths verifies purchase status locally and never receives your card details. Tenths Unlimited belongs to the Apple Account used to buy it and can be restored on your other Apple devices.
