What Is Flowkey?

Flowkey (flowkey.com) is a piano learning app available on iOS, Android, and as a browser-based web app. It teaches piano through song-based lessons using animated note waterfalls and video tutorials from professional pianists. Flowkey listens to you play via microphone or MIDI keyboard and provides real-time feedback on accuracy.

Flowkey's free tier includes a limited selection of songs. The full catalog of 1,500+ songs and all learning features require a Premium subscription at $9.99 to $19.99 per month depending on the plan length. Flowkey is designed for people learning to play piano, not for music producers who need frequency reference tools.

When to Use BeatKey Instead of Flowkey

No subscription budget

BeatKey Virtual Piano is fully free with no time limits, no credits, and no premium tiers. Play any note for as long as you want.

Production reference

Need to know that C1 is 32.7 Hz for your 808 bass? Or that A4 is 440 Hz? BeatKey shows Hz and MIDI numbers in real time. Flowkey does not.

Browser only, no app

BeatKey runs in Chrome, Firefox, Safari, and Edge on Mac, Windows, Linux, iPhone, and Android. No app download, no account, no setup.

Quick chord check

Want to hear what a Cmaj7 or Am9 sounds like before building it in your DAW? BeatKey has quick chord buttons for instant reference without lessons.

Why Hz Display Matters for Producers

Flowkey shows you which piano keys to press for a song. BeatKey shows you the exact frequency of every note you play. This distinction matters for:

  • 808 tuning: C1 = 32.7 Hz, D1 = 36.7 Hz. Knowing the Hz value lets you verify your 808 sample is pitched correctly relative to your track's key.
  • EQ decisions: If your mix has a resonance problem at 261 Hz, that is C4. You can identify which instrument is causing it musically.
  • Sample root notes: Load a piano sample into your DAW and verify it is tuned to the expected root frequency before pitching it up or down.
  • Vocal frequency range: Check whether a vocal part sits in the soprano (C4-C6), mezzo (A3-A5), or alto (F3-F5) range using Hz values.

Different Tools for Different Jobs

Flowkey is better when you want to:

  • Learn specific songs with note-by-note guidance
