CLUSTER DIARY-ENTRIES-PASSWORD · 23 ENTRIES · EARLIEST ENTRY 2017-06-26

Private diary and mood tracking apps

This cluster comprises private diary and mood-tracking apps that emphasize security (passwords, biometrics, local storage), photo support, and optional cloud sync. Entry dates are scattered across 2011–2026, with a small concentration in 2021–2023, but no clear trend shape emerges. Shanti Journal: Diary & Voice leads on traction signal, though all leaders show 0 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.
