Compatibility entries that need a caveat
Mac. App Store compatibility lists Mac, but the listing is marked "Not verified for macOS". This website therefore describes PDF JustFit as an iPhone and iPad app.
Apple Vision. App Store compatibility lists Apple Vision. This website does not make Apple Vision claims beyond what the App Store listing states.
Publishing the caveat is more useful than publishing an unqualified platform list, because a reader who needs a Mac app would otherwise install something that may not behave as expected.
Localization
Two figures are published: the App Store listing shows "English and 43 more", while the App Store product description states "Fully localized in 50 languages, including right-to-left support". Both are reproduced here with their source rather than merged into one number.
