Riffshed vs Reharmonizator

Riffshed is a practice journal for jazz musicians, built on the card system. See whether you're actually getting better — or just spending more time with the instrument. THREE PHASES. ONE CARD. Every exercise is a card that moves through three phases — Explore, Integrate, Master — each with its own color and rep counter. You decide when a card is ready to move forward; Riffshed remembers when it did and how long it stayed in each phase. REPS, NOT MINUTES A timer rewards sitting with the instrument. A rep counter rewards doing the work: running a phrase through twelve keys, taking a head clean. Minutes are still tracked — but reps are the unit you optimize. FOCUS BLOCKS A 20/5 focus cycle tuned for instrumental practice: twenty minutes on one card, five minutes of mandatory break. Both intervals are configurable; the open-ended mode drops the clock entirely for jams and lessons. START FROM ANYWHERE (new in 1.1) A Home Screen widget starts a session in one tap and shows today's minutes, your streak and the weekly goal. The live timer follows you to the Lock Screen and the Dynamic Island — pause and finish without unlocking; the session saves itself. Map practice to the Action Button, ask Siri, or add a Control Center switch. A METRONOME YOU'LL ACTUALLY USE Full-screen metronome with pendulum, subdivisions and swing. Configure click and accent per beat and per subdivision: silence the "and" of 2, accent any sixteenth, build polyrhythm grids. EVERYTHING LIVES IN THE CARD Notes, target tempo, separate rep counters per phase, PDF sheet music that opens full-screen (pages flip with a swipe while the metronome keeps playing), and one-tap links out to iReal Pro, YouTube, Spotify, Apple Music and more. SEE A YEAR OF WORK A calendar heatmap of your practice. Tap any day to see what you played, for how long, and which cards moved forward.
