CLUSTER TASKS-NOTIFICATIONS-REMINDERS · 25 ENTRIES · EARLIEST ENTRY 2026-07-10
Todo reminder apps
This cluster consists of basic to-do and task management apps whose core function is creating tasks and delivering due-date reminders via notifications. Dated entries are sporadic from April 2016 through October 2025, then appear monthly from April to July 2026, indicating a gradual increase in entry frequency in recent months. The traction leader is dot-tasks with 4 activity stars, while the other two members have 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.
