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

In the app package we scanned

No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Version 4.10.2 · 2026-10-23
FontFlex: Fonts for Safari Your font size now works on more websites. Some sites lock their text to a fixed size, so the size you picked in FontFlex was ignored there. FontFlex now overrides that, so the size you pick is the size you see. OpenDyslexic and Atkinson Hyperlegible no longer appear in System Fonts. Safari can't use them from that list, so picking one left pages in a different font. Both are still in Curated Fonts, where they work. The Studio preview now appears right away instead of waiting for fonts to download. It also no longer goes back to old settings when you return to FontFlex. New: Settings > About now shows your User ID. Tap it to copy it, and include it when you…

This list is cut off. Apple shows at most 10 in-app purchases, and this app is at the limit — so it very likely sells more than we can see.

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.
