About
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 and 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
