Rising themes
Risers rank by the week's percentage growth in each store's honest series - ratings on Chrome, Edge and Apple, users or installs elsewhere - above the store page's size floor, rising at least 5%, and leave out listings whose numbers do not add up. The grey line under a riser is what else happened to it in the fortnight (a featuring, a new version, a competitor leaving): alongside the rise, not offered as its cause. An edition is provisional while its week runs and frozen once it closes (Monday 00:00 UTC); weeks that ended before editions began were reconstructed from the census history, and what that history cannot support is marked unavailable.
