Hi, I’m Asher Zaczepinski, and I built Sheet Scan to make practicing music faster, easier, and way less frustrating. When I started learning clarinet, I was always looking for tools that actually helped me improve. Most apps were either too basic or too bloated—so I decided to build something better. Sheet Scan is an all-in-one app that helps student musicians scan their music and practice smarter. • Music Scanner + Recordings Take a photo of your sheet music and instantly get matched with full professional recordings from YouTube—filtered by your instrument and the exact piece you're playing. • Visual Metronome with Subdivisions Follow every beat and subdivision clearly with a visual metronome that helps you stay locked in. • Tuner with Instrument-Specific Tips Get real-time pitch detection, plus tuning advice tailored to your instrument—so you're not just told you're out of tune, you're told what to do about it. • Scales with Fingerings Access clean, accurate scales for your instrument, with sharps, flats, and fingerings already filled in—no more guesswork. Whether you’re prepping for band class, auditions, or just practicing on your own, Sheet Scan gives you the tools to actually improve—quickly, clearly, and in one place.
