Unlike traditional DAWs (Digital Audio Workstations) that require a MIDI keyboard to input notes, ScoreCleaner Notes uses pitch detection and rhythm analysis algorithms. You hum, whistle, or sing into your smartphone microphone. The app analyzes the frequency of your voice, identifies the scale and key, and then generates a clean, quantized score.

For a long time, the mobile version of ScoreCleaner Notes was the most accessible entry point. On the Apple App Store, the app has often been offered with a "freemium" model. This means you can download the application for free to test its capabilities.
