For jazz players · iPhone
Carve any recording into tight phrase loops, slow them down without changing the pitch, and drill them anywhere — on the train, on a walk, away from the horn.
Coming to the App Store — link goes live on approval.
The method
Every loop moves along one path. Learn to hear the phrase before you ever try to play it, get it under your fingers, then take it apart to understand why it works. Swipe a loop forward when you've got it — back when you don't.
"Woodshedding" is jazz slang for the solitary, repetitive practice that turns a phrase into instinct. That's the whole app.
What it does
Drag two handles around the exact phrase, set points on the fly while it plays, or subdivide a whole solo into a run of loops in one move.
50–100% speed with the pitch locked — a fast bebop line stays in key while you learn it. Seamless A–B repeat, with a draggable "repeat from" point.
Queue your solos — or every loop — back-to-back and let them run, hands-free. Bookmark the good parts to loop later. Sleep timer included.
Time accrues only while audio actually plays. Practiced vs. listening minutes chart across the week, month, year, and all time.
Tag loops ("ii-V-I", "rootless voicings"), filter instantly, and keep every loop grouped under its song. Back up the whole library as one file.
Full background and lock-screen playback, AirPods double- and triple-tap skips, and it plays even with the ringer on silent.
Woodshed won't play the phrase for you. It gives you the room to shed it until it's yours.
No account, no server, no analytics. Your recordings, loops, and practice history never leave your device.
