How can we help?

It's free to download. You get 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 and the markets you follow with alerts, plus one question a day to Ask, up to five a month.

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

Apple handles the billing, 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. Deleting the app doesn't cancel it.

Apple handles refunds. You can ask for one at reportaproblem.apple.com.

In the app, go to You, then Subscription, then Restore purchases, using the same Apple account you paid with. If that doesn't fix it, send us a message above.

US stocks and funds update every minute or two while the market is open. Markets abroad update more slowly: some during their own trading day, others only once they close, and a few figures, such as long-term US interest rates, are published once a day. The price line tells you when a price is live and when it's from the last close.

We value each company several ways using its official filings: the cash it makes, what its shares have usually cost, and what the market pays for similar businesses. We combine those with today's price into one figure and tell you how sure we are. It's an estimate, not a promise, and other sites will often land somewhere different.

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. Sources are named and linked under every story.

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

No. PreOpen is research and news. It isn't a broker, it doesn't connect to your brokerage account, and it never touches your money.

Not for most things. Without one, your setup stays on your phone. You need a free account to ask Ask a new question or to follow a market we don't track yet, and it keeps the markets you follow and your settings when you change phones. Sign in with Apple or with a code sent to your email. There's no password.

In the app, go to You, then Your data, then Delete account and data. It happens straight away and deletes your email address, the markets you follow, your saved items and your settings from our servers, and what PreOpen keeps on your phone. Questions you asked in Ask stay, no longer linked to you; write to us to have one removed. Copies in our backups are replaced within 7 days. Deleting doesn't cancel a subscription, so cancel that first. If you can't get into the app, write to us from the address you signed in with and we'll delete it for you.

No. We keep as little as we can, and the privacy notice lists all of it.

It's iPhone only for now. On an iPad it runs in an iPhone-sized window.

Please do. In the app, tap Report an error at the foot of the story or research page, or send us a message above with the company or story. We check every report, and we list our corrections on the Corrections page.
