Danu Finance — Educational Stock Screener

Features

Everything serious investors need.

Not tips. Not hot takes. Just rigorous, framework-driven screening and the data to back it up.

Intelligent Screener

Runs thousands of stocks through whichever investor lens you choose. Results scored and ranked in seconds.

Intelligent Screener

Choose from 16 legendary investor frameworks — Buffett, Graham, Lynch, and more — and Danu screens the entire market through that lens. Each result is scored and categorized as speculative, growth, or established so you know exactly what you're looking at.

How it works

Select a style, tap Run, and get a ranked list of stocks that pass that investor's real criteria — ROE, P/E, margins, momentum, and more. Filter by market cap, sector, or score threshold.

PRO

AI Analysis

Every screener hit gets a RACE brief — Role, Assessment, Context, Execute — powered by Claude AI.

AI Analysis

Tap any stock from a screener result to get an instant AI-generated RACE brief. The AI adopts the perspective of the investor style you chose and evaluates the stock against their actual criteria — explaining why it scored the way it did.

What you get

Role (which investor lens), Assessment (bull/bear case), Context (sector and macro), Execute (actionable verdict). Pro: 10 credits/day. Elite: 20/day + BYOAI for unlimited.

ELITE

Backtest Replay

Run your strategy against real history — server-side, so you can close the app and get notified when results are ready.

Backtest Replay

Pick any investor style, set a date range, and Danu replays the screener against real historical data. Results run server-side so you can close the app and come back when they're ready. See how your strategy would have performed over months or years.

Availability

Free: 3 replays/month. Pro: 3 replays/month. Elite: unlimited replays with priority processing.

Smart Alerts

Automated daily sell signals and style-aware take profit alerts. Runs at market close — never miss when it's time to act.

Smart Alerts

Danu monitors your holdings daily against the investor style you selected. When fundamentals deteriorate or your profit targets are hit, you get a push notification, Telegram alert, or Discord message — all automated at market close.

Alert types

Sell signals (fundamental degradation), take profit tiers (style-specific thresholds), and dangerous disconnect warnings (price up, fundamentals down).

Deep Dive Rankings

Screener candidates ranked and scored by your chosen investor style. Know at a glance which stocks score highest.

Deep Dive Rankings

One tap from the Screener tab runs a full deep-dive rank on your results. Each stock is scored across all the metrics that matter to your chosen investor — then sorted from strongest to weakest so you can focus on the best opportunities first.

Scoring

Composite score based on the investor's real criteria weighting. Buffett weighs ROE and margins; Graham weighs P/B and liquidity; Minervini weighs trend and momentum.

Biometric Security

Face ID and fingerprint lock. Your portfolio data stays on your device — we don't store your holdings.

Biometric Security

Danu uses Face ID and fingerprint authentication to protect your portfolio. Your holdings, cost basis, and trading activity are stored locally on your device — never on our servers. You control your data.

Privacy

No server-side portfolio storage. No tracking of your trades. Authentication tokens are stored in secure enclave via Expo SecureStore.

PRO

Sell Signals & Take Profit

Per-holding sell signals paired with style-specific profit tier alerts. Detects when price and fundamentals diverge.

Sell Signals & Take Profit

Each holding is monitored against the investor framework you chose. Graham gets tighter exit thresholds; Buffett gets wider ones. When fundamentals deteriorate while price stays high, Danu flags the dangerous disconnect before it becomes a loss.

How tiers work

Take profit triggers at style-calibrated thresholds. Sell signals fire on fundamental degradation — margin compression, rising debt, or earnings misses that break the original thesis.

News & Headlines

Latest headlines for your holdings from Yahoo and Google, surfaced right inside the app.

News & Headlines

Danu aggregates headlines from Yahoo Finance and Google News for every stock in your portfolio. No need to leave the app — scroll through the latest articles, earnings announcements, and analyst coverage right from the News tab.

Sources

Yahoo Finance and Google News, filtered and deduplicated for your specific holdings. Headlines refresh automatically throughout the trading day.

AI Chat

Ask about your holdings, run screeners, get portfolio insights — all from natural language.

AI Chat

A conversational AI that knows your portfolio, your investor style, and Danu's full feature set. Ask it to run a screener, analyze a stock, compare holdings, or explain why something scored the way it did. It can take action — not just answer questions.

Examples

"Run a Buffett screen on tech stocks" / "Why did AAPL score low on Graham?" / "What's my portfolio's biggest risk right now?"
