AutoPulse: OBD2 Scanner

Check engine light on? See what's actually wrong in plain English. Then track 0–60, g-force and your best roads on every drive. Works with any ELM327 adapter.

Know what your car is doing - and why.

AutoPulse pairs with a cheap Bluetooth ELM327 adapter and turns your iPhone into a live dashboard, a fault-code reader that speaks plain English, and a drive analyzer.

Stop guessing at the check engine light • Read stored, pending and permanent trouble codes • Every code comes with a real description — "Cylinder 1 Misfire", not just "P0301" • 9,000+ codes explained, fully offline, English and French • See the freeze-frame data from when the fault triggered • Clear codes once you've fixed it

Live engine data • RPM, coolant temperature, intake air, throttle, fuel trims, O2 sensors and more, updating in real time • Record a session and replay it later

Every drive, measured • GPS route map, speed-colored • 0–100 km/h / 0–60 mph acceleration times with a confidence rating • Peak braking, acceleration and cornering g-force • Distance, average and top speed, engine highlights, fuel-use estimate • Personal records that only count clean runs • Your favorite roads and corners detected automatically — beat your own best time

Private by design • No account, no sign-up • Your vehicle data never leaves your phone • Optional anonymous usage stats, one tap to turn off

Needs an ELM327-compatible OBD-II Bluetooth adapter (widely available, sold separately). Compatibility depends on your vehicle.
