Check back tomorrow — we need at least two days of data to draw a trend.
The ISC2 Official Exam Prep — learnZapp app in the Education category on the App Store peaked at #1 overall on 2026-07-27, and over the last 30 days has ranged between #1 (best) and #4 on average, indicating it recently slipped from its peak. Currently, however, it only appears in Top Grossing charts in smaller markets: Micronesia at #10 (down 1), Cameroon at #23 (down 8), Azerbaijan at #30 (steady), and Niger at #33 (down 4). All current entries are sliding or flat, with three out of four markets losing ground over the latest update. The trajectory is clearly cooling, with no appearances on the main Top Charts or in major markets in the current snapshot.
