A spectrum analyser in your pocket. Live waveform, real-time FFT spectrum and dominant-frequency readout from the phone microphone, in a clean interface with no decoration. For musicians, audio work, room checks and tracking down the source of a hum.





Real-time acoustic visualisation. Captures ambient sound, plots the waveform and FFT spectrum, and identifies dominant frequencies — for musicians, audio engineers, and field recording prep.
