The UK-based company, founded by David William Hearn and Matthew Tesch, has developed an advanced music composition application that converts handwritten notation into a music typeset score, automatically corrects stem directions, and adds courtesy accidentals. The app also highlights when there are too many or too few beats in the bar, and comes with a full orchestral sample library and unlimited staves. Composers can write music in their own handwriting, edit with touch, and hear their score played back with realistic sounds. StaffPad is compatible with mobile devices and optimized for touch and pen inputs.
