Chart read on 30 of the last 30 days.
Only the top-grossing chart counts. Top-paid charts are left out: paid-app sales are thin enough that almost any paid app reaches one. Each category chart lists the 100 highest-earning apps in that category on this store, so the bar is far higher in Games than in Medical.

21 of 75 apps are still gaining ratings, a median of 2.76 new ratings a day. 46 gained none in the last 30 days; 8 moved only once.

75 of 79 apps holding a top-10 position have rating readings spanning 14+ days.
App Store rating counts are kept per country, so these are App Store US ratings only. Google Play counts are worldwide. Compare apps within one store, never across the two. A rate is the rise in rating count over the days observed in the last 30 days; a drop of more than half is read as a counter reset and earlier readings are discarded.

COMPLAINTS
Too few complaints collected to summarise (18).
The store shows only a slice of reviews and skews positive — so the shares show which problems dominate, not how many users hit them.
