Stop ending practice with a question mark. Modacity is the Deliberate Practice System for serious musicians — helping you plan, record, reflect, and hear your progress session by session. USED BY PROFESSIONALS Serious musicians improve because their next session starts with a plan. "Musically life changing app! Amazing app that every serious musician should have! Bravo." -- Richard Stoelzel, President World Trumpet Society & Professor of Trumpet, McGill. "I am amazed how well the Modacity system works." -- Anne, amateur violinist “As a trumpet player (ergo, loudmouthed and opinionated) I’ve often been wrong. However, in this case I’ve never been wronger. The app has become the central pillar of my practice schedule and I’d be lost without it. With that in mind, the price is cheap!!” -- John Thirkell, trumpet & flugelhorn - Jamiroquai, Level 42, Buddy Rich Band "Swiss army knife to organize and focus my music practice. I can’t imagine my life without it" -- Armen, product manager & duduk player “Just wanted to tell you how helpful this app has been over the years. I got my first regional job at 640 hours and then one more regional gig and a one year with a big orchestra at 930 hours on the app.” -- Samuel Wamhoff, Principal Trombone - Modesto Symphony Orchestra; 2nd Trmb - Stockton Symphony; Acting 2nd - San Francisco Opera METRONOME — Professional-grade metronome with subdivisions, accent patterns, and tap tempo.
