Grip OBD

Turn your car into a live data lab. Real-time gauges, trouble-code reader, trip logging, an OBD console, and a dragstrip performance timer. Works in Demo mode too.

Grip turns your iPhone into a real in-car instrument cluster and diagnostic tool. Pair a standard ELM327 OBD-II Bluetooth adapter and watch your engine come alive with a premium, tach-grade dashboard.

LIVE DASHBOARD • Fast, beautiful radial gauges — RPM, speed, throttle, engine load, coolant, battery voltage and more • 17 live parameters, fully customizable — choose which gauges and tiles you see • Metric or imperial, your call

PERFORMANCE TIMER • Time a full-throttle pull straight off your car's speed signal • 0–60 mph, 0–100 km/h, eighth and quarter mile with trap speed, and top speed • Live splits, a speed-vs-time graph, and saved runs with personal-best tracking

TRIP LOGGING • Record every channel while you drive • Review RPM and speed graphs, session peaks, distance • Export any trip to CSV to dig in on your computer

TROUBLE CODES • Read the diagnostic trouble codes behind your check-engine light (Mode 03) • Plain-language descriptions for common codes • Read-only and safe — Grip never clears or writes anything to your car

OBD CONSOLE • Send raw ELM327/OBD-II commands and see the responses • Great for tinkering and learning the protocol

TRY IT WITH NO HARDWARE • Demo mode emulates a live ECU, so the entire app works before your adapter arrives

Everything runs on your device. Grip collects no data and transmits nothing to the internet.

Compatible with common ELM327 Bluetooth adapters (OBD, ELM, Vgate, Viecar, VLink and similar).
