App locking privacy tools

These products lock other apps behind biometric, PIN, or Face ID authentication to protect privacy and manage screen time. The pre-index dated history is sparse and scattered: a single entry in May 2020, one in November 2023, and four entries between March and July 2025. Traction leaders are OpenAppLock, SimpleAppLocker, and TrackerControl, each currently showing zero stars.

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.
