Fin Screener
Stock screener with Buffett/Graham/Lynch valuation built in
Fin Screener is an iOS app that screens 30+ exchanges across 13 countries (BIST, NASDAQ, NYSE, LSE, Euronext, Tokyo and more). For each stock it generates a full report: Piotroski F-Score, Altman Z-Score, Graham Number, Lynch fair value, DCF, margin of safety and buy/sell zones. No account needed — data stays on your device.
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!
