RPMBase
A digital garage for the car you own
RPMBase keeps service history, fuel, mileage, expenses and documents for your car in one place, then tells you what is due next. An assistant answers questions from the car's own records and turns receipt photos into entries.
What it does
Built around two questions every car owner has: what should I do next, and what has this car really cost me?
Your car, at a glance
The garage shows the car, its plate and VIN, key dates like insurance and inspection, mileage and spending, with quick actions to log fuel or a service.
Never miss a service
Activity lists what is coming up and when: oil changes, insurance, inspection and documents, each with a countdown, plus one-tap logging for fuel, service, expenses and mileage.
Costs that add up
Cost breakdowns split spending into service, fuel, parking and more, so ownership costs become a number instead of a feeling.
The car's whole story
Every milestone, from the purchase to the latest service, becomes a timeline you can share or export as a PDF, which is useful when it is time to sell.
