Performance meter
Dragy-style timing from the phone in your pocket — or import the Dragy log you already have. Every run is analysed on YOUR device (nothing is computed server-side), stored per car, and ranked on the public leaderboards.
Stand still, tap Start, launch when ready — the analyser finds the launch for you. It records 0-100, 60 ft, 1/8 & 1/4 mile with trap speeds, 100-200 and braking 100-0, plus slope and GPS quality. Everything is timed on THIS device — nothing is uploaded unless you save.
How accurate is it? Android Chrome samples GPS at up to 10 Hz (≈ ±0.1 s); iPhone Safari is capped at ~1 Hz by iOS (≈ ±0.2-0.3 s). Runs are badged so you always know what you are looking at — a Dragy import or a clean in-app run earns its badge.
Standing start: 0-100 and the distance splits need the car to be stationary when you launch; rolling pulls automatically skip them and keep 100-200. Braking needs one full 100 → 0 stop inside the recording.
Fair play: every run stores slope and density altitude, so downhill or cold-morning hero runs are visible to everyone on the board.
