Stock screener apps
This cluster comprises stock screening, scanning, and alerting applications, many focused on penny stocks and day trading. The dated history shows an outlier in 2010, then entries from 2018 through 2022, with a gap before 2025 entries. Traction leaders, all at 0 stars, are SmartMarketWatchlist, Stock Analysis: Stocks & Funds, and Screener.
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.
