Read full description

Crescendo is the practice journal for musicians who want to see themselves improve. Add the pieces you're working on, record a take whenever you sit down to play, and stack those recordings over time. Weeks later you can hear how far you've come — the passage that used to rush, finally steady; the phrase that finally sings. That arc, take by take, is the whole idea. Crescendo. WHENEVER YOU PLAY • Record audio or video takes in a tap, with a live level meter and a clean, focused recording sheet. • Import recordings you already have. • Star your best takes and add a note to any of them. Type a timestamp like 1:23 and it becomes tappable, jumping straight to that moment in your own recording. LEARN FROM A REFERENCE • Add a YouTube reference video to any piece. • Write freeform notes with timestamps — tap 0:42 to seek the video right to the bar you keep missing. • Slow it down, or loop a tricky section A→B until it's under your fingers. WATCH EACH PIECE GROW • Move songs from Up Next to Learning, Polishing, and Ready as they come together. • Organize by artist or composer, filter your library, and archive pieces without losing their history. PLAN YOUR PERFORMANCES • Build a recital, gig, or run-through with an ordered setlist. • Add your best practice takes, or record fresh ones for the day. • A readiness bar shows how prepared each piece is, and Rehearse Mode plays your setlist in order so you can run the whole show from start to finish. STAY ON TRACK • Set practice reminders for the days you want to play. • Everything lives on your device — fast, private, and yours. No account required. CRESCENDO PRO Crescendo is a complete practice journal for free. Pro adds, for the most dedicated: • Cloud backup to your own iCloud, so years of takes are always safe. • Studio recording quality — stereo, higher bitrate. • Slow-down and A/B loop on your own takes. • Unlimited performances. Pro is available as a monthly or annual subscription, or a one-time lifetime unlock, with a 3-day free trial on the subscriptions. Free users keep every part of the core journal — nothing you record is ever locked away. Whether you're learning your first piece or preparing for the stage, Crescendo helps you practice with intention and watch the progress add up.
