CLUSTER OPTIONS-DECISIONS-MAKE · 56 ENTRIES · EARLIEST ENTRY 2021-04-09

Decision support and comparison apps

This cluster comprises web and mobile apps that guide users through decisions using comparisons, voting, pros/cons lists, weighted criteria, or structured methods like AHP. The dated history shows entries scattered from April 2021, with a more regular presence from January 2025 through June 2026. The traction leaders by activity signal — Decision_Journal, sage-suggestions, and RedvsBlue — all have zero stars, indicating minimal user traction.

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.
