Themes and settings

Six themes, the measurement defaults, calibration, and three Shortcuts.

Verified for version 1.1.0 · Updated October 25, 2026

Settings is the gear at the right of the top row. From top to bottom:

Appearance
The theme. See below.
Measurement
Weighting (A, C, Z) and Time weighting (Slow, Fast, Impulse). See Sound level.
Device
Your model, the current Mode (Baseline or Calibrated, and whether a trim is on), Reference-tone calibration and the external mic file. See Calibration.
About Measurement Accuracy
What a phone microphone can and can't do. See How far to trust it.
Help
Reset coach marks brings back the two first-run pointers (iPhone only); Recordings opens the recordings list.
App
The version and build number, handy when you write in.

Themes

Studio Cyan
Dark · Pro mastering. The default: black with electric cyan.
Aurora
Dark · Expressive, holographic. Violet and pink over a deep purple glow.
Solar Flare
Dark · Warm amber sunset.
Graphite Safety
Light · Workshop tool, safety orange.
Arctic Cobalt
Light · Swiss, cool navy.
Tactical Violet
Dark · Tactical console layout. Pro.

Each theme recolours the whole app, charts included, and brings its own spectrogram palette. The first five are free.

Tactical Violet is part of Pro, and it changes more than colour: every screen gets its own console layout, with Japanese labels and small English captions. Without Pro it wears an orange lock; tap it to try the theme for 15 seconds, once each time you open the app. A countdown runs at the top, and when it ends the Pro sheet opens and your own theme comes back.

SoundMess Lab's Settings: the six themes with their colour dots under Appearance, Tactical Violet last, then Weighting A and Time weighting Fast, then Device with the model and Mode Baseline.

Shortcuts

SoundMess Lab adds three actions to the Shortcuts app and to Siri. Each one opens the app:

  • Show Real-Time Analyzer: opens with the RTA selected. "Show RTA in SoundMess Lab".
  • Start Recording: starts a new recording (Pro). "Record with SoundMess Lab".
  • Play Pink Noise: starts the pink-noise generator (Pro). "Play pink noise with SoundMess Lab".

Privacy

SoundMess Lab collects no data. The microphone is analysed on the device, and audio is only written to disk when you start a recording. There is no account and no cloud; see the privacy policy. If something isn't clear or isn't working, Support is one message away.
