Crank.

Track your BPM. Beat your personal records. Built-in metronome, progress charts, and streaks — everything a musician needs to practice smarter.

PRACTICE SMARTER. IMPROVE FASTER.

Most musicians practice blind — no data, no feedback, no idea if they're actually getting better.

Crank changes that.

LOG YOUR BPM Record your speed for any fragment, lick, or technique. Every session tracked, every improvement visible.

WATCH YOURSELF IMPROVE Beautiful progress charts show your BPM climbing over time. See exactly how far you've come.

KNOW WHAT TO PRACTICE Smart sorting puts your most neglected fragments at the top. Never wonder what to work on next.

CELEBRATE YOUR WINS Hit your target BPM? You're In Progress. Blow past it? You're in Overdrive Ready to move on? Mark it Mastered

ORGANIZE YOUR PRACTICE Collections let you group fragments your way — by song, technique, or whatever makes sense to you.

STAY CONSISTENT Streaks, heatmaps, and personal records keep you accountable and motivated.

Built-in metronome with tap tempo, subdivisions, and multiple sound types — everything you need in one app.
