More from our data
Counted by the week their id was created, the first week above 100 was Dec 15, 2025 (163), and the peak was 311 in the week of Aug 31, 2026. The 8 settled weeks to Sep 21, 2026 have a median of 244. Only apps live in the directory are counted, so the latest weeks stay low until their apps go live (right-censoring).
Apps SDK ids start with plugin_asdk_app_ and decode to a creation time. See app id family.
