# Piano One

> Piano One is a mobile app (iPhone and Android) that teaches piano. It listens to your own piano or keyboard through your phone's microphone and guides you note by note, from your first C to your first song. No MIDI cable and no special hardware needed.

The site and the app are available in English and French. The French site lives under https://piano-one.com/fr (for example https://piano-one.com/fr/faq).

## Key facts

- Who it is for: complete beginners and adults who want to learn on the instrument they already have.
- How it works: the app shows the next note to play, you play it on your piano, and Piano One hears you and moves on when you play the right note.
- Compatible instruments: acoustic piano, digital piano, or a simple keyboard.
- Pace: a lesson takes about 5 minutes, and ten minutes a day is enough to make progress.
- Content: from finding your first note (C) to reading sheet music, using both hands and playing real songs (Hot Cross Buns, Ode to Joy, original Piano One pieces).
- Pricing: the first lessons are free, with no card needed. The Piano One Premium subscription unlocks the whole learning path and every song. Payments go through the App Store or Google Play.
- Account: no account to create.
- Privacy: sound is analysed live on the phone and then forgotten. Nothing is recorded or sent to servers.
- Download: [App Store](https://apps.apple.com/app/id6815796349) (iPhone) and [Google Play](https://play.google.com/store/apps/details?id=com.nosse.pianoone) (Android).
