How it works
Ten drills, five pillars, one score that means something.
Purple reads your pedals directly, at the resolution your hardware allows. No wheel, no car, no circuit — just the input, measured properly.
Plug in and go
Purple finds your pedals on its own. Two minutes on first run and you never think about it again.
Any pedals
Fanatec, Heusinkveld, Moza, Simagic, VNM, Simucube — any quality load-cell set, including mixed rigs.
Nothing else needed
No wheel, no sim title, no second subscription. Purple runs on its own.
The drills
Each one isolates a single link in the chain.
Reaction drills add difficulty modes — standard, anticipation with feints, and a degrading cue that fades the longer you wait.
Reaction
Brake · Throttle · ClutchCue to movement, one pedal at a time.
Dual pedal reaction
Brake + ThrottleRandom target each rep. Wrong pedal counts as an error.
Transfer time
Throttle → BrakeHow long the car spends with no input acting on it.
Pressure hold
Brake or ThrottleHit a target by feel. Blind and visual modes.
Consistency
Brake or ThrottleThe same input, rep after rep. Variance is the score.
Pressure tracing
BrakeFollow a moving curve without overshooting.
Brake ramp
BrakeReal curve profiles — GT3, Cup, Formula, Touring.
Heel-toe
Brake + ThrottleHold pressure and blip without disturbing either.
Bilateral independence
Brake + ThrottleTwo feet, two tasks, at once.
Cognitive load
Brake + ThrottleGo / no-go reaction while carrying a second task.
The pillars
Five scores you actually train against.
Drills feed pillars. Your weakest pillar drives what Purple puts in front of you next, so training time goes where it is worth the most.
Assessments
A protocol, not a practice session.
A baseline takes five drills and about ten minutes. The full assessment runs the complete protocol. Both are self-contained snapshots — scored only from the drills completed in that sitting, never from all-time bests — so two assessments months apart are directly comparable, and a driver being tested for the first time gets a clean, honest number.
Baseline
Five drills. Where you stand today.
Fast enough to run at the start of a session, or on a driver who has walked in the door ten minutes ago.
Full assessment
The complete protocol. Exports a report.
Every pillar covered, every drill scored, and a three-page PDF at the end of it.
The report
Something to hand a driver.
Every full assessment exports a three-page PDF, written to be read by the driver and presented by the coach. It is the difference between a number on a screen and a document someone takes home and acts on.
Run it again in six weeks and the report shows the change, pillar by pillar.
The scores
Overall rating and tier, the five-pillar radar, and every pillar's change since the last assessment. Drill-by-drill breakdown underneath.
What it means on track
Milliseconds converted into physical consequence — reaction into metres travelled, transfer time into coast distance per braking zone, inconsistency into braking-point scatter.
Coaching notes
Strengths and priorities, behavioural symptoms to watch for on track, prescribed drills with a frequency, and a re-test date.
Faster feet. Faster laps.
Windows 10 and 11. Works with any quality load-cell pedal set.
