ThrustMetric — Vehicle Performance & Diagnostics Suite

ThrustMetric turns your phone into a precision driving instrument — GPS speedometer, drag-test timer, OBD2 diagnostics, and G-force/attitude sensing, with optional external RTK GPS and Bluetooth IMU support for racing-grade accuracy.

Performance Testing — Sprint tests (0→60/100/120/160 km/h), braking test with live stopping-distance bar, quarter-mile/400m with trap speed, lap timer with best-lap highlight, auto-arm launch, power estimation (kW/hp).

Real-Time Instrumentation — GPS+IMU fused speedometer, longitudinal/lateral/composite G-force, altitude, 3D attitude ball (4 selectable fusion algorithms), Bluetooth external IMU/RTK GPS support (e.g. RaceBox) for higher precision.

OBD2 Vehicle Diagnostics — Connect a Bluetooth OBD2 adapter to read live engine data and scan fault codes.

Trip Recording & Analysis — Summary stats, speed/G charts, 2D color-coded map, 3D relief route, elevation profile.

Toolbox — Bonus Instruments — Celestial/satellite compass with real-time tracking (TLE-based), bubble level & inclinometer, decibel meter, acoustic RPM meter, automotive NVH (vibration order analysis), vibration meter, and a voiceprint matcher for identifying and comparing sounds.

Garage & Track Library — Manage multiple vehicle profiles in My Garage, and browse a library of 3,000+ preloaded tracks worldwide for lap timing.

AI-Assisted Health Check (optional) — Upload an ECG recording/photo for an AI-generated waveform read-out. For reference only, not a medical diagnosis. Processed via cloud AI, requires subscription.

Account & Sync — Sign in with Google to sync data and unlock subscription AI features. Core tools (GPS, drag test, lap timer, OBD) work fully offline, no account required.

Requires GPS and motion sensor permissions.
