App Store pages list at most 10 in-app purchases and do not order them by price. 1 of these 3 apps filled that limit, so their price is the highest of the items shown, not necessarily the highest they sell. Google Play prints one price range instead, and its upper end is the real top.
REVENUE CHARTS
1 of 88 apps holding a top-10 position sat on their category's top-grossing chart on at least 3 of the last 30 days.
| App | Category | Best rank | Days on chart |

| Trill: Ear Training Daily | Music | 75 |
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.

COMPLAINTS
Too few complaints collected to summarise (0).
The store shows only a slice of reviews and skews positive — so the shares show which problems dominate, not how many users hit them.
