Vroomist

Vehicle Performance Meter

Free

Measure 0-60, quarter mile, and more with pro-grade GPS accuracy. Connect your RaceBox, Dragy Lite or use your iPhone's built-in GPS to get started. Vroomist turns your iPhone into a precision vehicle performance analyzer. Connect a RaceBox GPS, Dragy Lite device via Bluetooth for professional-grade measurements, or use your iPhone's built-in GPS. SPRINT MEASUREMENTS Measure acceleration times across any speed range. Built-in presets include 0-60 mph, 60-130 mph, 0-100 km/h, 100 - 200 km/h and dozens more. Create your own custom sprint specs for any speed range you want to test. DRAG RACING Track your 1/8 mile, 1/4 mile, 1/2 mile, and full mile times with trap speed readouts. Add custom distance targets to match your local strip. SLOPE-CORRECTED TIMES Every sprint and drag result includes a slope-corrected time that estimates your flat-ground performance. Vroomist divides each run into segments and corrects each one individually based on its actual elevation change — so hills, dips, and rolling terrain are all accounted for, not just the difference between start and finish altitude. GPS LOGGING Record full GPS sessions to capture every detail of your run — speed, altitude, G-force, and distance — all timestamped and stored locally. REAL-TIME CHARTS Watch your speed, G-force, and altitude update live on a customizable chart. Adjust the time or distance window, tweak G-force smoothing, set dead zones, and zoom in for a closer look. After a run, compare multiple measurements side by side with overlay charts. SHIFT & SPEED ALERTS Set a shift point and Vroomist beeps when it's time to shift. Set a max speed alert and get notified the moment you hit it. Both work in the background while you drive. WEATHER & DENSITY ALTITUDE Vroomist automatically captures temperature, humidity, barometric pressure, and density altitude with every measurement, so you can correlate performance with environmental conditions.
