Play

All 88 keys, under every finger.

Slide the miniature piano at the top to move along the whole keyboard, from the lowest A to the highest C. Then play with every finger: chords, both hands, all at once.

Slide the miniature

The bar at the top is the whole piano, in small. Slide it and the keyboard follows.

Every finger

Multi-touch from the first note: a chord, two hands, a melody over a bass line.

The whole width

Turn your iPhone on its side. The keyboard takes the screen from edge to edge.

Calm

Nothing between you and the keys.

No account, no ads, nothing to set up. Open it and play.

The room around the keyboard takes the colour of a warm material.

  • Ochre
  • Linen
  • Cinnamon
  • Greige
  • Midnight

Ochre comes with the piano. The other four come with Piano Pro.

Support

The keyboard stays free, forever.

If you would like to support us, Piano Pro adds themes, sounds and a metronome, for a very affordable price. It keeps the studio going, and it never takes anything away from the free piano.

Before you ask

Which devices?
iPhone, with iOS 26 or later. Piano plays in landscape only, so the keyboard gets the whole width of the screen.
What is free?
The whole keyboard, all 88 keys, with the Ochre theme and the Grand sound. It stays free, forever.
What does Piano Pro add?
Four more themes, three more sounds and a metronome — as a lifetime purchase or a yearly subscription, both through the App Store.
I already bought Piano Pro. How do I get it back?
Open the ⋯ menu, choose Piano Pro, then Restore Purchases. Piano Pro follows your Apple Account.
Do I need an account?
No. Nothing to sign up for and nothing to sign in to.
Are there ads?
None, and nothing that follows you across other apps. Piano counts a few anonymous events; the privacy page lists every one.
