Dynometry — vehicle telemetry, garage log, and closed-course performance instrumentation. YOUR CAR'S DATA, IN ONE PLACE Dynometry turns your iPhone into a precision vehicle instrument. See live speed, distance and trip time on a clean dashboard. Keep every vehicle you own in the Garage with its specs and measurement history. Review past sessions any time in your personal History. TRIP DASHBOARD • Live speed, distance and duration at a glance • A clear, glanceable layout designed for mounted use • Metric and imperial units • GPS speed is shown for reference — always verify against your vehicle's speedometer GARAGE • Keep all your vehicles with detailed specs, weight and drivetrain • Each car's measurement history kept separately • Your history is stored on your device TRACK MODE — CLOSED COURSES ONLY For drag strips, track days, autocross, dyno verification and private-property testing, Dynometry includes an optional Track Mode. It is off by default. Enabling it requires accepting a closed-course use acknowledgment, and you confirm your venue before each session. With Track Mode enabled: • GPS and motion-sensor timing — 0–60 mph, 0–100 km/h, quarter mile, braking distance, standing and rolling starts • Dyno-style horsepower and torque estimation computed from sensor data, so you can check what a remap, intake or exhaust actually changed • Distance splits, plus speed and G traces for every run • Automatic run analysis that reports whether a measurement was clean — for example, flagging a lift or brake application that makes a time unrepresentative of the vehicle IMPORTANT — SAFE USE Track Mode is designed for closed courses, racetracks, drag strips and private property only. You must accept the safe-use acknowledgment before any timing feature becomes available, and confirm your venue before each session. Never use performance features on public roads. Never attempt a measurement in traffic. Always obey all traffic laws and drive responsibly. BUILT LIKE AN INSTRUMENT Mount the phone, run a pass, read the results afterwards — no interaction is needed while the vehicle is moving. Accuracy depends on GPS conditions and a correct vehicle weight; for best results use a windshield or vent mount and a flat, straight surface at a sanctioned venue. FREE AND DYNOMETRY PRO Free: the trip dashboard, the Garage with no limit on vehicles, your own measurement history, the CarPlay dashboard, and the 0–60 mph / 0–100 km/h, 0–30 mph / 0–50 km/h, 50–75 mph / 80–120 km/h, 1/8 mile and 60–0 mph / 100–0 km/h measurements, with no limit on how many you take. Dynometry Pro adds the rest of the measurement catalogue — including the quarter mile, the longer standing and rolling measurements and the extended braking set — plus the Advanced start mode, the full report for every run (distance splits, speed and G traces, run statistics, conditions and the automatic analysis), high-quality vehicle renders in the Garage, result images without the watermark, and History without ads.
