About this app

Return to focus.

MONO is an interactive attention laboratory. Follow a moving dot, listen as a tone fades, or return to the rhythm of your breath.

Choose a practice. Give it a minute or two. When your attention wanders, come back.

PRACTICE YOUR ATTENTION…

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

Store update history

App Store

Version 1.0.2 · 2026-10-03
Three new ways to return to focus: Color cadence, Undertone, and Bubble bath. • Create your own practice playlists. Choose the order and duration, and start each practice when you're ready. • Meet MONO through a new interactive introduction with touch and haptics. Replay it from Settings. • Shape your ambient soundscape while MONO is open. • Enjoy richer color in Room to breathe, haptics as the bloom expands and retracts, and Last sound moving with your global sound mix. • Smoother Home interactions and refinements to sound, touch, and motion. • Add MONO to your Home Screen: your weekly practice wheel, with a daily quotation in the medium widget.

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.
