REVENUE CHARTS
None of the 45 apps holding a top-10 position reached a top-grossing category chart in the last 30 days.
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.
RATING GROWTH
3 of 43 apps are still gaining ratings, a median of 0.2 new ratings a day. 36 gained none in the last 30 days; 4 moved only once.
| App | Released | Ratings now | New ratings per day |

| Photo Timer+ | 2012 | 8,471 | |
| Video Stopwatch SC | 2018 | 402 | |

43 of 45 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.
