CLUSTER TIME-REMINDER-NOTIFICATIONS · 32 ENTRIES · EARLIEST ENTRY 2021-01-03

Simple reminder scheduling apps

This cluster consists of basic reminder apps focused on scheduling one-time or recurring date-and-time notifications, with options for custom messages and alert types. Dated entries appear irregularly from October 2011 through July 2026, with the most entries in any single month being three (July 2025) and some months having none, indicating a sparse, long-tail pattern rather than a concentrated burst. On traction, Stochastic Reminder, tides-up, and Al-Toque all show zero stars, suggesting minimal user engagement or adoption.

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.
