Good to know

What is PreOpen?

PreOpen is an AI stock research and market news app for iPhone. It gives a fair value from company filings and a 0–10 score on 500+ US stocks, explains why markets move, and tells you what matters before the market opens.

What's free, and what does Plus cost?

Free gives you the headlines and the start of every story (the day’s biggest stories in full), Today’s Read, Before the Bell, prices and charts, one PreOpen Score a day, the calendar, lessons, the markets you follow with alerts on your own stocks, and one question a day to Ask, up to five a month.

Plus adds every story in full, the PreOpen Score and rankings for every stock, fair values, the four ratings, bull and bear points, the Screener, Smart money, 50 questions a month to Ask and more alerts. It’s $149.99 a year with a 7-day free trial, or $29.99 a month.

Where do the numbers come from?

Companies’ own SEC filings, official sources such as central banks, and published news, named and linked under every story. Prices come from Twelve Data and CoinGecko, and economic figures from the Federal Reserve Bank of St. Louis.

Is it made by AI?

Partly. Scores and fair values come from fixed rules, the same for every stock. AI (Claude, made by Anthropic, and Grok, made by xAI) writes the stories and powers Ask, and our Guardian checks each new piece against our data.

Can PreOpen pick stocks for me?

It does a lot of the research and shows you how each stock rates and why. But it doesn’t know your whole situation and it can be wrong, so the decision is always yours.

Can I trade inside PreOpen?

No. PreOpen is research and news. It isn’t a broker or an investment adviser, it doesn’t connect to your brokerage account, and it never touches your money.

How do I cancel Plus?

Apple bills it, so you cancel on your iPhone: Settings, your name, Subscriptions, PreOpen. Do it at least 24 hours before your free trial ends or your plan renews. You keep Plus until the end of the time you’ve paid for. Refunds go through Apple at reportaproblem.apple.com.

Where can I get it?

It’s coming soon to the App Store, for iPhone, and free to download.
