Gauger: Performance Meter

Measure what your car actually does — with the phone already in your pocket. Gauger uses your phone's GNSS and motion sensors to time acceleration and rolling starts. No imported GPS box, no customs, no extra hardware. MEASURE • Acceleration — 0-60 / 0-100, the quarter mile, and timers you choose yourself • Rolling — an A-to-B interval from a moving start (e.g. 60-130) • Your own targets — any speed interval or distance HANDS OFF WHILE DRIVING You arm the run while stopped. The launch, the intermediate targets and the finish are detected automatically, with audio cues. Your eyes stay on the road. HONEST NUMBERS Speed comes from GNSS Doppler, fused with the motion sensors. The conditions measured — signal quality, the road's grade — are shown alongside the time, because a time means nothing until you know the conditions it was set in. We never inflate a result. REPLAY AND SHARE Watch your run play back on the gauge. Turn a time into a shareable card in one tap — free. YOUR GARAGE Add your cars — make, model, engine and model year, chosen from a list, never typed. Every run records the car that set it, and the car travels with the time onto the board and onto the card you share. LEADERBOARD AND PROFILE Send a standard run to the board and see where you stand. Tap a rank to see what backs it: the interval, the grade, the signal quality. Your profile is your public card. HEAD TO HEAD Tap any time on the board and watch it race yours. Two cars on one road, each driven from the run its driver actually recorded, with the gap between them live as it opens — ending on a result card that puts both times and both curves side by side. FREE, AND FAIR Every measurement type and every headline result is free — nothing is crippled, and measuring is never capped. The free tier caps how many verified runs you save to the cloud each day and how many head-to-head races you watch. Premium lifts both caps, replays any of your runs, unlocks the raw telemetry graph (the real acceleration channel under the speed curve, peak g, road grade) plus the detailed split-by-split analysis, and customizes your profile card. One quiet subscription, no dark patterns. SAFETY Gauger measures. It does not guide your driving and does not encourage speeding. Use it only where it is legal and safe — a closed road, a track, or wherever the rules allow. Speeding on public roads is illegal and dangerous. The road is your responsibility. PRIVACY Your location never leaves your device. Only the run's speed-vs-time curve and its derived results are uploaded — your coordinates are never sent, and never stored.
