Lemonscope: Used Car Check

Buying a used car? Turn the test drive into evidence. Lemonscope uses your iPhone's motion sensors during a normal test drive, adds a guided walk-around checklist and free U.S. government vehicle data, and gives you a clear verdict with talking points you can use to negotiate. KNOW WHAT YOU'RE BUYING BEFORE YOU PAY FREE VIN CHECK - Scan the VIN barcode or type it in. - Decoded by NHTSA: year, make, model, trim, engine and transmission. - Recall campaigns and owner complaints for that model year, from NHTSA. HANDS-FREE TEST-DRIVE MEASUREMENTS Mount the phone, or let a passenger hold it, and drive a normal route. Lemonscope detects each test automatically and tells you by voice when it's captured: - Idle vibration: engine shake and idle speed while parked. - Suspension: how quickly the car stops bouncing after a bump (worn shocks keep bouncing). - Brakes: firmest stop, pull to one side, and pulsation. - Straight-line tracking: steering wander on straight roads. - Acceleration and shifts: harsh shifts or slipping. - Cabin noise (optional, microphone level only, no audio recorded). GUIDED WALK-AROUND Exterior, tires (penny test, DOT date code), under the hood, interior, electronics, and title and paperwork red flags, with plain-English tips and optional photos. A REPORT YOU CAN PUT ON THE TABLE - Verdict: Looks good, Ask questions, or Walk-away signals. - 3 to 6 negotiation talking points with typical U.S. repair-cost ranges. - A suggested offer range from the asking price. - Share it as a PDF. DRIVE SAFELY Set up while parked. While the car is moving there is nothing to tap, and voice cues keep your eyes on the road. Lemonscope never asks you to speed or make unusual maneuvers.
