Rung: Skill Tracker

You're practising hard, but the progress doesn't match the effort. The plateau stretches on. Here's the uncomfortable truth: you're probably practising the right skill at the wrong stage. Most people train for stage three when they're still at stage two, and that misalignment wastes months.

Rung is a skill tracker built around four stages of competence. Each stage prescribes a different action, and your stage is derived from your practice attempts. Never guessed, never self-assessed.

STEP ON: define the skill. List up to 5 steps and 3 variables. Minimal theory, then enable practice. Or adopt one of 30 pre-built skills from the seed catalogue and skip straight to experimenting.

STUMBLE: surface mistakes. Log attempts with success and effort. Every miss becomes a what, a why, and a next experiment. Progress here means running out of new mistakes.

CLIMB: build reliability in strict order. Consistency first, then ease, then speed. Rung picks your weakest sub-skill first so practice goes where it counts.

HOLD: maintain or decay honestly. Around 95% success with low effort across 10+ attempts earns Hold. Stop for 14 days and the skill slides back a stage instead of pretending. No streaks to break, just the truth.
