## What is Vroomist?

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.

SUPPORTED DEVICES
• Dragy Lite (up to 25 Hz GPS, selectable 10/20/25 Hz sample rate)
• RaceBox Mini (25 Hz GPS)
• RaceBox Mini S (25 Hz GPS)
• RaceBox Micro (25 Hz GPS)
• iPhone Internal GPS (1 Hz)

APPLE WATCH
See your live speed, device connection status, and measurement results right on your wrist.

DATA EXPORT
Export individual results or bulk-download your entire measurement history as CSV files in a ZIP archive. Filter by measurement type and time range. Save chart images to your photo library.

FULLY CUSTOMIZABLE
• Metric or imperial units for speed, temperature, and distance
• Custom sprint and drag specifications
• Adjustable slow-run filters to automatically discard poor results
• Chart draw rate, zoom, smoothing, and visibility toggles
• Sound and haptic feedback options
• Per-car measurement profiles

PRIVACY FIRST
Your data stays on your device. Vroomist stores everything locally with no cloud uploads, no accounts.
