About this app
PianoFold is a piano rhythm game from Vision First Studio that works through the classical repertoire. Tiles travel toward a row of pads, and tapping them in time plays the melody while the accompaniment fills in around you. The game has 40 levels split across eight chapters, with pieces by composers including Beethoven, Chopin, Mozart, Bach and Tchaikovsky, from Ode to Joy to Für Elise. Long tiles have to be held, combos build as you keep time, and each song can be replayed for three stars. There are no lives or timers, so a failed attempt can be retried straight away.
Every unlocked song also has a practice room. You can slow the music down, play the left hand, the right hand or both, and swap the falling tiles for an on-screen keyboard. A Wait for me option pauses the music until you play the next note, which makes it useful for learners as well as for people who just want a game.
You can play against a dark stage or in a Room view that uses the rear camera to show the space in front of you as the backdrop; the developer says nothing is recorded. The first two chapters are free, a daily free song opens up from chapter two, and a single Full Game purchase unlocks the rest, with no ads or subscription. It runs on iPhone and iPad as well as iPhone Duo.

How it uses iPhone Duo
The developer describes PianoFold as built for iPhone Duo and lays it out for each pose. Folded like a laptop, the notes fall on the upright half, the pads sit on the flat half and the strike line sits on the hinge, with the upright screen showing the room through the rear camera. Opened flat, the notes and pads meet on the fold. Closed, the whole game runs on the outer display like on any iPhone. DuoDiscover has not yet tested it on a device.
