Hi Product Hunt! 👋 I built Fin Screener because I was frustrated with stock screeners that either ignore non-US markets (especially Borsa Istanbul) or lock fundamental metrics behind clunky web tools. Fin Screener runs natively on iOS and lets you: - Screen 10+ exchanges (BIST, NASDAQ, NYSE, DAX) by RSI, P/E, P/B and volume - See Piotroski F-Score, Altman Z-Score, Graham Number and DCF for each stock - Track a portfolio and export results to Excel/PDF - Use it in 10 languages, with no account and all data stored on-device It's free to use, with a Pro tier for unlimited reports and advanced filters. Happy to answer any questions — feedback on which exchanges or metrics to add next is very welcome!
