Piano Scale Coach

Most practice apps count minutes. Piano Scale Coach counts what matters: clean, focused reps. Built on practice principles from peer-reviewed learning research — and the way piano teachers have taught for centuries — it walks you through all 12 major scales, one key at a time, until your hands just seem to know the way. THE METHOD • Perfect reps, not minutes. Four clean in a row before you move on — the error-fixing habit research found in the most effective pianists. • Small chunks that grow. Three notes become four, then five… then one fluent octave — the way expert pianists' brains actually organize scales. • Hands separate, then together. Each hand learns its pattern first, so your full attention is free when they join. • Earn your speed. The built-in metronome climbs only when you're accurate — so you never rehearse mistakes. • Test yourself. Quick scale-degree quizzes in every session, because self-testing beats reviewing in study after study. • Short sessions, spread out. Six focused sessions per key, a few each week — spacing is one of the most replicated findings in learning science. WATCH IT STICK Your circle-of-fifths map fills in key by key, with your best tempo logged for every scale. Research on goal tracking says visible progress keeps you coming back — and it feels great. SIMPLE, HONEST PRICING C major is completely free — all six sessions and the scale test. One single purchase unlocks the other 11 keys. No subscription. No ads. Your practice data stays on your device. Sit down. Three notes. Begin.
