How this is counted

We count the reviews we hold again every week. Every star counts. Each number compares this app with the norm. It is how much more or less a topic comes up here than in Education apps. A topic shows once 20 of this app's reviews mention it. Searches are what Apple shows for its market's searches in the US.

Stores: we ask Apple about each app in 41 stores every week. A dot is green when that store's name, text or screenshots differ from the US ones. It is red when they are the same. The apps beside this one have the most ratings in its market.

Releases: a dot is a new version, on the day Apple gives. A hollow dot has the same notes as the one before. This app's date turns red after 30 days with no release. That happens only when at least 3 other apps in its market released in that time.

Stars and ratings are Apple’s.
