About this app

Kreyon is a drawing, painting and comic studio for iPad and iPhone. It gives you brushes that behave like real media, a full layer system and a workspace that stays out of the way, whether you are doodling for the first time or finishing a page for a client.

Free to start, one purchase for the full studio

Draw, paint, letter and export for free, with no account and no ads. Kreyon Studio is a single one-time in-app purchase with no subscription. It unlocks non-destructive Adjust, the Brush Studio, more than five layers, 4K canvases and full-resolution export. If you bought the app before it became free, Kreyon Studio is already unlocked for you.…

Version 3.6.21 · 2026-10-30
Kreyon gets a fresh new look. - Two themes: choose the new Kreyon theme, warm cream inspired by kreyon.digital, or keep Classic dark.

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.
