How to Practice Piano on iPhone or iPad (Mic Mode Guide)

Apple's iOS doesn't support Web MIDI or Web Bluetooth — so on iPhone and iPad, the microphone is the only way to get live grading. Here's how to set it up so it actually works well.

Why MIDI doesn't work on iPhone or iPad

Apple's WebKit (the engine behind every iOS browser, even Chrome and Edge for iPhone) blocks both Web MIDI and Web Bluetooth over fingerprinting concerns. There's no roadmap to add it.

The good news: mic mode works on every iPhone, iPad, and Mac with Safari — and it grades any acoustic or digital piano without needing a cable.

How mic mode works

Tap the 🎤 Mic button in the floating panel. The browser asks for microphone permission — tap Allow.

The badge flips to 🟢 Performance mode and the song's audio is muted so we only hear your real piano. Play and we detect the pitch in real time.

Setup for accuracy

Mic mode works best when:

The mic is close to the piano — phone propped on the music rest works fine; tablet on a stand near the piano too

Background noise is low — close the door, no TV in the room

You wear headphones for any backing track — the song's audio is muted so we don't pick it up, but if you ever want a click track, headphones keep your mic clean

Will it grade as accurately as MIDI?

For monophonic melodies (one note at a time), yes — pitch detection is reliable. For dense chord work, MIDI is still better because chord pitch detection is inherently fuzzy. Start with single-line pieces in Performance mode, then graduate to chords once you trust the setup.

Browser tips

iOS — Safari, Chrome iOS, and Edge iOS all use WebKit, so all three work the same. Pick whatever you have open.

Mac Safari — works the same way; mic-only is fine if you'd rather not switch to Chrome.
