CLUSTER APPOINTMENT-MANAGE-REMINDERS · 68 ENTRIES · EARLIEST ENTRY 2013-07-19

Appointment scheduling apps

This cluster of 69 products consists of appointment booking and scheduling apps for service professionals, small businesses, and freelancers, commonly covering calendars, client management, reminders, payments, and reporting. The dated entry history shows a thin, sporadic trickle from 2012 through 2025, with monthly counts mostly at one or two; from early 2026 monthly entries rose to three to five, a modest pickup rather than a sharp change. On traction, snagtime leads with 330 stars, while the other two named members show zero activity signal.

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.
