Hi Product Hunt! 👋 I built Fin Screener because most stock tools either ignore non-US markets or stop at basic screening. I wanted something that does the hard part — actual valuation — automatically, on a phone. For any stock across 30+ exchanges (13 countries, from BIST and NASDAQ to Tokyo and Tadawul), Fin Screener generates a full report inspired by Graham, Lynch and Buffett: - Graham Number, Lynch fair value (PEG=1) and DCF - Margin of safety + upside potential - Buy/sell strategy zones and a 0–10 investment score - Piotroski F-Score, Altman Z-Score, full risk breakdown It's free for up to 4 full analyses per day, with Pro for unlimited analysis and advanced screening. No account, data stays on-device. Honest note: data is delayed (via TradingView), so it's built for evaluating companies, not intraday trading. Feedback on which exchanges or metrics to add next is very welcome!
