Vroomist vs PitLaunch

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.

PitLaunch turns your iPhone into a pocket performance timer. Line up, launch, and get your real 0–60 — timed to the hundredth of a second. PitLaunch fuses GPS speed with your iPhone's motion sensors to time your run the instant you launch. No extra hardware, no wires — just mount your phone and go. PitLaunch is free to download. Timing runs and all the features below require PitLaunch Pro, an auto-renewing subscription (monthly or annual) purchased in the app — the price is always shown before you subscribe, in your local currency. WHAT YOU CAN TIME (requires PitLaunch Pro) • 0–60 mph (or 0–100 km/h) • The quarter mile — with ⅛-mile split, trap speed, and 0–100 mph • Roll-on pulls like 50–70 mph • Peak G, plus a live G-meter that tracks g-forces in every direction BUILT FOR ENTHUSIASTS • Standstill or 1-foot rollout — the same conventions as the drag strip • Automatic launch detection: arm it, drive, and PitLaunch captures the whole sheet for you • A big, glanceable readout designed to be mounted and read at speed • Works in mph or km/h SHARE YOUR RUNS Every run becomes a clean, branded card — your time, your car, and the real speed trace — sized for Instagram and ready to post in a single tap. YOUR DATA STAYS YOURS PitLaunch runs entirely on your device. Your location, motion, and run history never leave your iPhone. No account, no sign-up, no analytics, no tracking. DRIVE RESPONSIBLY PitLaunch is intended for use on a track, a closed course, or a legal venue. Never interact with the app while driving — set it up before you set off or have a passenger operate it, and always obey speed limits and local laws. PITLAUNCH PRO — SUBSCRIPTION REQUIRED All features described above — timed runs, every captured metric, shareable run cards, and your run history — require PitLaunch Pro, an auto-renewing subscription available monthly or annually. The current price and billing period — and any introductory offer — are always shown in the app before you subscribe, in your local currency. — Subscription details — • Payment is charged to your Apple ID at confirmation of purchase. • Your subscription renews automatically unless cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the period ends. • Manage or cancel anytime in your Apple ID account settings. • Any unused portion of a free trial, where offered, is forfeited when you purchase a subscription.
