Fixie connects to your car through any common OBD-II Bluetooth adapter and gives you the full picture: every module on the network, fault codes with plain-English explanations, live sensor data, emissions readiness, and verified code clearing.
Download on the App StoreFinds every control module the car exposes — engine, transmission, ABS, airbag, body, cluster and more — across all the networks the vehicle actually has, then shows the whole tree.
Open any module and read its stored, pending and permanent codes with explanations. Clearing is verified: Fixie re-reads after the clear and tells you if a code came back.
Generic OBD-II plus brand-enhanced parameters: per-cylinder misfire counters, transmission temps and pressures, wheel speeds, battery health — whatever the vehicle serves.
Monitor-by-monitor readiness with honest not-supported handling — know before the inspection station does.
VIN, calibration IDs and CVNs straight from the modules — catch swapped or reflashed ECUs.
Scans, logs and settings stay on your phone. No accounts, no tracking, no ad IDs. Optional cloud features only run when you tap them.
Cheap no-name adapter? Fixie probes the standard service layouts too, retries clones that wake slowly, and tells you plainly when an adapter is a known counterfeit.
*MS-CAN and SW-CAN need a multi-bus adapter (OBDLink MX+ class). Fixie detects your adapter's capability and never pretends a bus is reachable when the hardware can't get there.
