CHOOSE THE BEST SENSOR SOURCE Use iPhone GPS and motion sensors, a compatible Bluetooth or Wi-Fi OBD-II adapter, or an external GPS receiver. G-Box Dyno automatically prioritizes a connected high-rate source and records source quality with every run. BUILT FOR REPEATABLE TESTING - Vehicle profiles with mass and gear calibration - Power and torque curves versus engine RPM - Automatic shift detection and useful run trimming - Atmospheric data for consistent comparisons - CSV telemetry and saved run history - Portrait and landscape analysis views - Optional rear-camera video with synchronized acceleration overlays FREE TO START Create one vehicle and complete three measurements with the standard 0-60 and 0-100 presets.

SAFETY AND MEASUREMENT NOTICE Use only on a closed course or private road where legal. Configure the app while parked, mount iPhone securely, and never interact with the screen while driving. Performance results are estimates and are not certified dynamometer measurements. Accuracy depends on sensor quality, calibration, vehicle data, road grade, traction and weather.

Verdict
The clearest difference is in-app purchases: OMaps at none against G's 1. G's advantage is update cadence (every 2 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
