WatchSignal - AI Stock Signals

AI signals with plain-English reasoning. News sentiment, RSI, MACD, watchlist alerts, and a portfolio health score. Start a 7-day Signal+ trial free.

Most "AI investing" apps want to trade for you. WatchSignal explains what your stocks are doing, on your phone, with confidence numbers you can audit - and never asks for your brokerage password.

Type any US ticker. The on-device AI reads price, momentum, news sentiment, and earnings context, and surfaces a Bullish, Neutral, or Bearish signal with a calibrated confidence percentage and a plain-English breakdown of the factors behind it.

No account linked to a broker. No server inference. Your watchlist never leaves your phone.

WHAT MAKES WATCHSIGNAL DIFFERENT

On-Device AI The AI ensemble runs entirely on your iPhone - faster, more private, and offline-capable. Most "AI signal" apps call a remote server. We don't.

Calibrated Confidence Every signal carries a confidence percentage that means what it says. When the app shows 70%, roughly 70 of 100 such signals were correct on the walk-forward validation set. We publish the accuracy methodology at watchsignal.ai/accuracy.

Plain-English Drivers For each signal, see which technical factors - trend, RSI, MACD, volatility, news sentiment - drove the model's view. Not a black box.

Earnings Intelligence For tickers with upcoming earnings, see the options market's implied move, the consensus EPS estimate, the direction of analyst revisions, and the last 8 quarters of estimate-vs-actual surprises and price reactions.

Sentiment + Price Together News-headline sentiment is blended with technical indicators. When news flow and price action agree, the signal looks stronger. When they diverge, that's flagged.

Deep-Dive Analysis Candlestick chart with timeframe selector, volume, sector context, earnings calendar, key statistics, options pulse, and similar tickers - all in one place.

Why We Never Connect to Your Broker WatchSignal does not link to Robinhood, Webull, Public, eToro, Schwab, Fidelity, or any brokerage. We do not execute trades. We do not auto-rebalance portfolios. Subscription-only revenue means we have one job: help you decide. Read watchsignal.ai/no-broker for why this matters.
