Private journaling apps
This cluster comprises private journaling and diary apps that prioritize on-device or encrypted storage, password or biometric protection, and features such as photos, mood tracking, and prompts. Creation dates span from 2011 to 2026, with sparse monthly counts overall but a noticeable rise in early 2026. Traction leaders by activity signal are Orin-, Seclog - Private Feed Journal, and Day One: Daily Journal & Diary, each with 0 stars.
Entry timeline
ENTRY TIMELINE
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.
