Common questions
Is it really free?
Yes — the free tier includes daily AI signals, a 10-ticker watchlist, the stock Screener, the Sector Radar with end-of-day refresh, basic portfolio tracking, and a limited number of alerts. Signal+ unlocks unlimited alerts, real-time signal updates, the live Radar, smart rebalancing, tax-loss harvesting, the full Forecast Accuracy suite, and insider transaction history. You can try Signal+ free for 7 days, no payment up front.
What data do you collect?
Your portfolio, watchlist, alerts, and trading activity stay on your device — they are not uploaded. We use Sign in with Apple to authenticate your account and sync minimal personalization preferences (such as experience level and interests). Market data and SEC filings are fetched on demand from Polygon; subscription billing is handled by Apple. We use no third-party analytics or tracking SDKs.
How accurate are WatchSignal's AI signals?
Every signal carries a calibrated confidence percentage. When the app shows 70%, roughly 70 of 100 such signals were correct on our walk-forward validation set. Backtested directional accuracy varies materially by horizon and market regime, and past performance does not guarantee future results. AI signals are statistical model outputs, not investment advice. See our full methodology at watchsignal.ai/accuracy.
Does WatchSignal connect to my brokerage?
No. WatchSignal does not link to Robinhood, Webull, Public, eToro, Schwab, Fidelity, or any brokerage. We do not execute trades and we do not auto-rebalance portfolios. Subscription-only revenue means we have one job: help you decide. Read watchsignal.ai/no-broker for why we built it this way.
What stocks does WatchSignal support?
WatchSignal currently covers US-listed equities, including S&P 500 names, major ETFs, and a wide range of liquid mid-caps. Type any US ticker — if there is enough price history, the AI will analyze it. International markets are on the roadmap but not yet supported.
Can I use WatchSignal on Android?
Not yet. WatchSignal is iPhone-only because the AI ensemble runs entirely on your device, and we wanted to ship the best possible experience on a single platform first. An Android version is on the roadmap but does not yet have a release date.
