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 · Clutch

Cue to movement, one pedal at a time.

Dual pedal reaction

Brake + Throttle

Random target each rep. Wrong pedal counts as an error.

Transfer time

Throttle → Brake

How long the car spends with no input acting on it.

Pressure hold

Brake or Throttle

Hit a target by feel. Blind and visual modes.

Consistency

Brake or Throttle

The same input, rep after rep. Variance is the score.

Pressure tracing

Brake

Follow a moving curve without overshooting.

Brake ramp

Brake

Real curve profiles — GT3, Cup, Formula, Touring.

Heel-toe

Brake + Throttle

Hold pressure and blip without disturbing either.

Bilateral independence

Brake + Throttle

Two feet, two tasks, at once.

Cognitive load

Brake + Throttle

Go / 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.

ReactionHow fast the signal gets from your eyes to the pedal.
AccuracyWhether you land on the pressure you intended.
ConsistencyWhether you can do it again, and again.
TechniqueThe mechanical craft — heel-toe, ramps, curve shapes.
Cognitive functionWhat survives when your attention is divided.

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.

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.

Faster feet. Faster laps.
