Biggest opportunity: Swap “calculator” and “due date” for “fertility” and “menstrual cycle”. “calculator” isn't earning its slot: you're not in the first 24 results for its own search. “fertility” sits at #5 untagged, close enough for a declared tag to move it up. “due date” isn't earning its slot: you're not in the first 24 results for its own search. “menstrual cycle” sits at #5 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 100 of 7.9K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,764 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

Directory rank
Ranked about #13,300 to #16,400, alongside the other plugins at 100+ installs. Plugins with the same install count swap places between wp.org requests, so this is where most of them sit. Checked monthly, last on 21 Oct 2026.
Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
No release in a yearHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.
