Klassian

Don't turn the page. Just look. While you play, your hands should belong to the sound alone. Pedaling, nodding, catching your breath: your body is busy enough already. With Klassian, you simply look at the spot where the page should turn, and it turns. Keep both hands on your instrument. GAZE-DRIVEN PLAYING - Smart gaze detection: Klassian finds where the music ends on each page and sets the turn zone for you. - Precise control: dwell time and zone size are carefully designed to prevent accidental turns. - Made for you: it learns your habits and keeps adapting as you play. PRIVACY AND RELIABILITY - On-device processing: all gaze processing happens on your iPad. - Works offline: play with confidence in halls and practice rooms with no internet connection. THE FEEL OF PAPER - Natural annotation: pen, highlighter and stamps, just as you would mark a paper score. - Smart viewer: two-page spreads, portrait and landscape, and Split View to fit your setup. - Smart navigation: set the markers once, and Klassian follows repeats, D.C., D.S. and codas for you. YOUR PARTNER IN MUSIC - An organized library: gather scores in any format and sort them by composer and instrumentation. - All-in-one schedule: practice, performances and fees, all in one place. - Groups: announcements, schedules, scores and polls, shared with the people you play with. - Seamless sync: read scores on iPad, manage your schedule on iPhone. One subscription covers every device. REQUIREMENTS iPad Pro (2018 or later), iPad Air (3rd generation or later), iPad mini (5th generation or later) and iPad (8th generation or later). No pedal, no remote. SUBSCRIPTION Klassian Pro and Klassian Max are offered as monthly or annual subscriptions. Your local price is shown in the App Store before you subscribe.
