H3ARD

Built for musicians, students, and the endlessly curious, H3ARD makes it easy to identify notes by ear, isolate a passage, and loop it back until it clicks. Pinch to zoom in for pinpoint accuracy, and let H3ARD automatically label the notes it detects across your recording. Everything runs entirely on your device. Nothing you record is ever stored, uploaded, or shared.
