CLUSTER REAL-TIME-DATA · 21 ENTRIES · EARLIEST ENTRY 2011-04-05
Market & portfolio tracker apps
This cluster consists of stock, crypto, ETF, forex, and multi-asset tracking apps that provide real-time quotes, watchlists, portfolios, and alerts. Entries were created steadily from 2009 to 2025, mostly one per month, with a small pickup in early 2025. The traction leaders are Freedom24, Koyfin, and market-watch-dashboard.
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.
