About this app

Make the music visible, and turn your iPhone or iPad into the retro audio display your stereo deserves.

LaZ Visual Audio Equalizer is now LaZ Viz Audio Visualizer. The name has changed; the free v2.0 upgrade brings more ways to see your music.

LaZ Viz listens through your device's microphone and turns the sound around you into dancing spectrum lights, moving needles, glowing waves and whole worlds that come alive with the music.

Version 2.0 brings rebuilt audio analysis, refreshed VU and McVU meters, native iPad layouts and layouts designed for iPhone Duo from day one.

Made for Duo:

Open, fold and rotate with layouts that follow the space available. VU meters can occupy separate fold regions. Phosphor keeps its round scope and controls within reach. Partially fold Duo in Jeep Beach for a dedicated JUMP panel alongside the scene.…

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
