CLUSTER SCREEN-LOCKS-DEVICE · 8 ENTRIES · EARLIEST ENTRY 2017-04-30

Screen lock utility apps

The cluster comprises mobile apps that lock the device screen, either instantly, after a timer, via missed tap detection, or through gestures, serving uses like parental controls and kiosk mode. Their dated history is thin: entries appear in six months from April 2017 to July 2026, with at most two in a single month and long gaps between, so no clear shape is discernible. Traction is led by SleepGuard, Pineapple Lock Screen, and TapLock, each with 0 stars, indicating minimal community engagement.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 8 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
