ScooterCheck

About this app

Never buy a used e-scooter blind again. Stand next to it, tap Scan, and ScooterCheck reads the battery, motor, controller and fault registers straight off the scooter over Bluetooth, then tells you whether to buy it, look closer, or walk away. It is free, and there is nothing to buy. You get a plain-language verdict backed by a 0 to 100 health score and a ranked list of findings. FREE, WITH ADS The full inspection is free. Every report, every finding, the spec sheet and the shareable card. A short full-screen ad plays while your report is being prepared, and that is what pays for the app. No subscription, no in-app purchase, no account. Not sure it works with your scooter? Tap "See a sample report" on the first screen and look at a complete inspection first. WHAT IT CHECKS Battery: measured capacity against the model's design capacity (state of health), pack voltage at charge, cell temperature, charge level. Wear: calendar age from the detected model, total distance ridden. Faults: active error and warning codes, decoded to plain English. Configuration: speed limit, firmware version, showroom/demo-mode firmware. Drive electronics: motor and controller temperature. Every deduction shows the raw reading behind it. No black box. WHAT IT CATCHES Tired batteries. A pack at 62% of its design capacity is flagged with a rough replacement cost, so you know what you are negotiating over. Wound-back odometers. If measured battery wear does not match a suspiciously low mileage, the report says so, on brands where that is possible. Demo-mode firmware. Showroom mode quietly limits what the scooter will do. Invisible while riding, disqualifying if you are paying full price. Permanently restricted speed. On some hardware a lowered speed cap can never be raised again. Not a setting, but a permanent reduction in what you are buying. HONEST ABOUT WHAT IT CAN'T SEE Every report carries a confidence rating: how much of the scooter actually answered. A scooter that hides data scores lower, not higher, because opacity is a finding too, and the report lists what it could not check. (The app is in seven languages; the detailed finding explanations are English only.) SUPPORTED SCOOTERS Verified on real hardware: Xiaomi M365, Pro, Pro 2, 1S, Lite (including newer Mi-Auth firmware) MiniRobot M0Robot (e.g. Sparke) Also supported, detected automatically on connect: Ninebot ES1, ES2, ES4 Segway-Ninebot MAX G30 and G2 (encrypted firmware) E-Wheels E2S, E2S V2, E7, E12, M6 KingSong "KS-…" Navee ST3 and ST3 Pro Minimotors: Dualtron, VSETT, Kaabo, Apollo Phantom Swagtron Swagger 5 VMAX VX2 Recognised but not inspectable: Xiaomi's newest scooters and newer E-Wheels models keep their data behind an encrypted or cloud-authenticated channel. The app names these when it sees them and says why, rather than spinning. FACTORY SPEC SHEET For 24 catalogued models, compare the scooter in front of you with the one that left the factory: capacity against design, top speed against the factory rating, and the years the model was sold, so "barely used" gets a date check. SHARE THE REPORT Selling instead of buying? Export the inspection as a square image for your listing. A scored, timestamped report beats "battery is fine, trust me". READ-ONLY, ALWAYS ScooterCheck never writes to the scooter. It reads, scores, and disconnects. Nothing is changed, unlocked, tuned or reconfigured. You are inspecting someone else's property, and the app treats it that way. The inspection runs on your phone: no account, no ride history, nothing tracking how you use the app. After your first report you are asked once whether ScooterCheck may send its inspections back to us, so we can fix scoring gaps and support more scooters. Say no and nothing is ever sent. Say yes and only the scooter goes, never a serial number in the clear and never anything about you. You can change your answer on the scan screen at any time.

ScooterCheck is now completely free. The full inspection, every finding, the spec sheet and the share card. There is no purchase and no subscription. A short full-screen ad plays while your report is being prepared, and that is what pays for the app. MORE SCOOTERS Navee ST3 and ST3 Pro Minimotors: Dualtron, VSETT, Kaabo and Apollo Phantom Swagtron Swagger 5 VMAX VX2 Xiaomi's newest scooters are recognised now too. They keep their battery and mileage behind an encrypted channel ScooterCheck cannot read, so rather than connecting and coming back with nothing, the app names the scooter and tells you why it cannot inspect it. Older Xiaomi models running the newest Mi-Auth firmware (1.4 and later) authenticate correctly again. If a Pro 2 or 1S would not connect before, try it now. SHARING YOUR INSPECTIONS, IF YOU WANT TO After your first report, ScooterCheck asks once whether it may send its inspections back to us. It is entirely optional. Say no and nothing is ever sent, and you are not asked again. Say yes and what goes is the scooter: brand, model, score and the readings behind it. Never a serial number in the clear, never anything about you or where you are, and never the other Bluetooth devices around you. You can change your mind on the scan screen at any time. This is how we find the gaps in the scoring and decide which scooters to support next. Thank you to everyone who has downloaded ScooterCheck. More brands are on the way.
