CLUSTER DIARY-PIN-DAILY · 7 ENTRIES · EARLIEST ENTRY 2022-08-24

Secure mood diary apps

This cluster consists of diary/journal apps that combine daily entry writing with mood tracking, photo support, customizable themes, and PIN or biometric protection. Among the seven pre-index dated entries, the timeline is sparse and irregular: one entry each in Aug 2022, Oct 2022, Jan 2023, and Apr 2023, then a long pause before Jul 2024, Sep 2024, and Apr 2025. On traction, all leaders are at 0 stars; Miuu Note: Cute Diary Journal ranks highest, followed by Diary with Lock: Diary Journal and My Secret Diary - Journal.

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 7 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
