Split-Flap Mechanical Engine + Performance Intelligence

AI-POWERED ADAPTIVE PRACTICE BUILT AROUND YOUR WEAKNESSES.

Flapboard measures your micro-hesitations, finger transition latency, and error clusters on a tactile split-flap departure board—then generates targeted adaptive drills to permanently eliminate typing bottlenecks.

Platform Architecture

YOUR TYPING IS MORE THAN WPM

Flapboard isolates the physical mechanics behind speed, accuracy, and hesitation.

SPEED

Net & Raw WPM

Real-time words-per-minute calculated with O(1) running keystroke latency performance.

ACCURACY

Split-Flap Feedback

Physical 3D card flips immediately highlight clean hits (amber) vs mistypes (red).

CONSISTENCY

Sparkline Rhythm

Keystroke-by-keystroke speed stability tracking across every second of your test.

FINGERPRINT

Weakness Diagnosis

Per-key latency and hesitation analysis identifying exact finger bottlenecks (Platform Direction).
