AI coaching · HPDE & track days
The coach that doesn't get out.
Coldwire rides every session, knows the line you should be running, and tells you the one thing to fix — where you braked late, where you lifted early, where the time went. On the phone already in your pocket.

What you get
Coaching, not a spreadsheet.
Lap timers hand you numbers and wish you luck. Coldwire reads the data the way an instructor would — and talks to you the same way.
Hot Wash
Best lap, delta to last session, and the one thing to fix before you go back out. Read it before your helmet's off.
Debrief
Corner-by-corner breakdown of the whole session. You braked late into 1 every lap. You lifted in 5 where the car had more. Plain language, no chart-diving.
Range Card
Your reference sheet for the track: brake markers, gears, and personal bests, corner by corner — built from your own laps.
How it works
Mount. Drive. Listen.
Mount your phone
Windshield mount, camera facing forward. Coldwire uses the phone's motion sensors and GPS — the same dual-band hardware that costs more than an entire entry-level lap timer when bought on its own.
Drive your session
Coldwire records quietly: position, braking, cornering forces, and synced video. Works with zero cell signal — paddock dead zones don't matter.
Pull in and get the truth
The debrief is waiting before you're out of the car. Blunt, specific, and it remembers every session you've ever run together.
Coldwire is in active development. Android ships first, iOS follows. Founding grid members get early builds, a direct line to shape the coaching, and free access at launch. If you run HPDE events and want in early, this is the moment.
Your fastest lap is in there. Let's go find it.
