Custodian Car Care
In testing · Android
Coming soon

Keep the history.
Transfer the trust.

Custodian keeps your car's whole life in one place: every oil change, repair and part, the codes it throws, and the photos to prove it. When you sell, the new owner scans a QR code and the full record goes with the car.

Service history

Every job, logged

Oil, brakes, tires, mods. Date, mileage, cost, who did it and the photos, all on the car's own page. Works offline in the garage and syncs when you're back on WiFi.

OBD-II scanner

Read the codes

Plug in a Bluetooth adapter to read trouble codes in plain English, watch live data, check the battery, and see if codes were cleared right before a sale.

QR transfer

Sell with proof

Selling? Hand the buyer a QR code. The full history, scans and photos move to their account, so the car's story stays with the car.

A logbook that survives the sale

Paper receipts get lost and the glovebox folder rarely makes it to the next owner. Custodian keeps the record with the car, ready to share as a PDF report or hand over in one scan.
