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

Store update history

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

Version 2.0 · 2015-09-24
• Updated for iOS 9 - our apologies for those users who couldn't use the app on iOS 9 until now. • Added Fractional Inch sizes up to 7 inches. • Added Metric sizes up to 180mm. • Added a table to show Fractional Inch sizes reduced down to X/64 and X/32. • UI updated for iPhone 5, iPhone 6, and iPhone 6 Plus. • Search function: since the tables are longer now, we added a search bar at the top of all tables (scroll up to access it). • Universal app - download it on your iPhone & iPad • New home screen layout and info section in Settings.

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.
