Growth
Change in installs, scaled to each window from the real gap between crawls. This store refreshes its install counts only occasionally, so these figures usually read 0 even for a listing that is growing - the weekly change in ratings under Rating above is the better signal here. A window needs a full period of history before it reports anything.
| Per | Growth | Growth % | Actual change | Measured over |
|---|---|---|---|---|
| day | 0 | — | 0 | 1.1 days |
| week | 0 | — | 0 | 8.9 days |
