What is your car worth today?
Scan the VIN once. Known prices your car from real sales and live listings of cars like it, keeps the number current, and keeps the service file that holds it up.
Your first car is free.

Real numbers, with the evidence under them
Every number says what it stands on and when it was read. Too few sales or listings means no number at all, never a guess.

Tested, not promised. We check every kind of number against prices it never saw. For one car at its own mileage, the way the app prices it, half land within 5% when the number comes from listings, and within 17% when it comes from auction sales, which scatter more.

Then keep it worth that
A buyer can't check what you can't show them, so they assume the worst. In a survey of 2,034 drivers by HPI, 82% said they would walk away or ask for a discount on a car with no service history. Known makes the history the easy part.
- The schedule. What is due, worked out from your own mileage, with the age of the reading beside it.
- The logbook. Two taps to log a service. Entries are never edited, so a buyer can trust them.
- Reminders that show their work. Rare, and each one says what it was worked out from.
- Recalls. Open campaigns for your year and model, labelled as exactly that.
- The history document. Every service, dated and mileage stamped, as a PDF to hand a buyer.
One car is free
Free
Your first car
The schedule, the logbook, reminders, recalls, the odometer, and a dated estimate. For as long as you own it.
Plus
$4.99 a month, or $49.99 a year
Every car in the garage, the estimate kept current with the sales and listings behind it, a push when it moves, and the history document. On the App Store it is $5.99 and $59.99.
What Known will not do
- Show a guess as if it were a fact.
- Give a number when too few cars like yours have sold or are listed.
- Rewrite a service entry. A correction is a new entry.
- Show a mileage without saying how old the reading is.
