About this app

Track Evolution is a personal HPDE / track-day logbook: events, sessions, lap
times and notes per track, with progress charts that show you getting faster
season over season. Free to use, and your data stays yours.

RECORD LAPS WITH YOUR PHONE
Time your laps live using your phone's GPS — no separate lap timer or camera
needed. Recording keeps running in the background and survives the app being
swiped away.

IMPORT TELEMETRY YOU ALREADY HAVE
Drop in footage or logs from a Corvette PDR (Cosworth) video, a GoPro, or a
Racelogic VBO file, and Track Evolution turns them into sessions with laps, a
drawn racing line, and per-lap speed/RPM/G-force graphs. Everything is parsed
on your device — video and GPS traces are never uploaded.

PROGRESS CHARTS THAT MEAN SOMETHING
See your best lap per track and layout trend down over time, overlay laps
against each other, and get consistency, best-N average, and pace-trend
stats that go beyond a single best time.

GARAGE & SETUP NOTEBOOK
Track consumables — pads, tires, fluids — per car with wear estimates and
replacement projections based on hours on track. Log a setup sheet for each
event day and diff it against your lap times to see what actually helped.

YOUR GARAGE, YOUR CARS
Keep your cars and modifications in one place, set a default car for new
events, and link setups back to the laps they produced.

SHARE YOUR PROGRESS
Generate a read-only public link to your stats page under a slug you choose
— private notes, emails, and garage details are stripped automatically.

WORKS OFFLINE
Built offline-first — log a session in the paddock with no signal, and it
syncs the moment you're back online.

FREE, NO ACCOUNT HASSLE
Sign in with your existing Google account. No paywall, no ads, no account
setup beyond that.
Track Evolution requests location access (including in the background) only
to record laps via GPS while you're on track, and a notification permission
to show the active-recording status. Learn more at
