CLUSTER MILESTONES-BIRTH-BIRTHDAY · 15 ENTRIES · EARLIEST ENTRY 2022-07-21
Birthday and anniversary reminder apps
This cluster consists of apps and web services focused on tracking birthdays, anniversaries, and other special dates, with features like countdowns, notifications, contact imports, and calendar syncing. The dated history before the index start is thin and irregular—single entries in 2012, 2017, 2022, 2025, two in 2020-09, and one in 2026-01—so no clear timeline shape emerges. All traction leaders show zero stars, with birthday-app, Birthday Adapter, and day-book-app having the highest activity signal.
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.
