Car maintenance log that builds a resale-ready service history

The problem

Owners of older cars carry the maintenance history themselves, and receipts end up in glove boxes and email. The next buyer can't see what was done, which costs the seller money. Mileage-based reminders need the odometer reading, which most apps make tedious to update.

For: Owners of older cars · Private-party sellers · Households with 2-4 vehicles

Why now
