Foldeon

Start free with Ode to Joy. Unlock the full songbook with one purchase. Made for iPhone Duo, with touch bellows on every iPhone and iPad.

Designed for iPhone Duo. A little fold, a little folk.

Turn your Duo into a pocket concertina: gently open and close the fold to give the music its air. On other iPhones and iPads, drag the red touch bellows. Closed Duo also plays with touch on its outer screen.

START PLAYING FREE Ode to Joy is included in both Demo and Learn modes. In Demo, we press the notes while your movement sets the pace. Tap Learn it to follow the glowing keys yourself.

UNLOCK THE FULL SONGBOOK One optional, non-consumable purchase unlocks all six songs in Demo and Learn modes: Ode to Joy, Twinkle Twinkle Little Star, Frère Jacques, When the Saints Go Marching In, Drunken Sailor and Scarborough Fair. Pay once, with no subscription. Restore your purchase on your other devices using the same Apple Account. Customers who bought the paid version of Foldeon keep all songs.
