Every rep counts. Log your BPM after each session and watch fragments climb into OVERDRIVE. You'll know the exact day a lick goes from grind to mastered. Crank. is the gym tracker for musicians. Pick a lick, riff, scale, or any fragment you're working on. Log your BPM after every practice and watch the line climb. No streak guilt. No wellness fluff. Just proof you're getting faster. TRACK WHAT YOU PRACTICE • Create fragments for anything: licks, solos, scales, rudiments, études • Log BPM + how it felt in seconds, right after you play • See every fragment's progress chart climb toward your target • Hit your target BPM to enter OVERDRIVE, then push past it PRACTICE LIKE A WORKOUT • Build multi-fragment sessions like a gym routine • Crank It Up: nail a rep, add a new row at +1 BPM • Session summary with personal records and practice time • Attach your sheet music or tabs, right where you practice FREE METRONOME + TUNER • Precise metronome with subdivisions, sounds, and tap tempo • Built-in chromatic tuner, always one tap away • Both free, forever SEE YOURSELF GETTING BETTER • Practice heatmap, streaks, and weekly stats • Level up through 10 ranks as your hours stack up • Set deadline goals and let Crank pace the BPM steps • Records board: fastest fragments, biggest jumps, longest sessions Works offline in any practice room. Dark interface built for late nights. Your data syncs when you sign in, free. Crank Pro adds unlimited fragments, more goals, weekly review, and video recording.
