About
Tap a piano key. Press Write. That's a song — chords underneath, a tune on top.
Keysong is a one-screen piano for people who don't play piano. Pick a home note, choose a mood, and it writes a short piece in that key, plays it, and lets you keep the sound. It also teaches you 17 well-known songs one lit key at a time, and records what you play.
The piano sound is clear and full on the iPhone speaker — no headphones needed. Or plug in a USB MIDI keyboard, or pair a Bluetooth MIDI keyboard, and play real keys.
No account. No internet. Nothing leaves your device.

What's New in Keysong
1.0.1
November 2, 2026
A key you hold down now keeps ringing for as long as you hold it, like a real piano, instead of stopping after five seconds. Works with a finger, the computer keyboard, and a MIDI keyboard's keys or sustain pedal.
