CLUSTER CALENDAR-MOBILE-SCHEDULING · 16 ENTRIES · EARLIEST ENTRY 2015-02-26

Calendar-integrated task managers

This cluster consists of mobile task-management and to-do apps that combine calendar views, widgets, and sometimes weather or analytics, with a few desktop or cross-platform variants. Dated entries are sporadic from 2011 to 2025, showing no strong concentration across years, though there is a slight clustering in 2015–2016 and again in late 2025; one member lacks a source date. Traction leaders are To Do List - Reminders & Tasks, Task Manager: Daily To-Do, and TaskCal, all with zero 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.
