About

AlphaFlow Invest

Features

US stocks come with too many numbers. P/E, ROIC, free cash flow β€” it's hard to know where to start, so most people buy on someone else's word. AlphaFlow puts those numbers into plain language, and locks none of them away β€” every figure in this app is free. Check once a day how the market moved, then take your time working out whether a company you like is actually a good one. β–  Once a day is enough Last night's US session, in one line across the three major indexes. The day's news is grouped into a few themes, each marked as helpful or harmful to someone holding for the long run. Inflation, jobs, the Fed's policy rate and retail sales come with the date of the next release. Oil, gold, the dollar, bitcoin and liquidity show a three-month move and what it means for a stock holder. Sector performance is a treemap β€” each tile's area is its market cap, so you see where the money went. β–  Take one company apart, properly Search a ticker and the cards answer in order. How much does it earn? How much actually stays β€” margins, free cash flow? Is it built to last β€” returns on capital, cash vs debt? Is the price fair β€” DCF fair value, P/E, analyst targets? Every card leads with a verdict above the chart β€” "Growth holding", "Strong returns" β€” the answer first, the evidence after. If a metric is unfamiliar, the explanation is right there. You can also see whether insiders bought with their own money, and where options have clustered. β–  One page a week, per company AI insight reads the week's public news on a company and lays it out on one page: what happened, what reads as a tailwind, what reads as a risk, and the source behind each line. It summarizes what is already public β€” it never says what to buy. β–  Read by the measure built for that strength Every company is strongest on one axis β€” durability, value, or growth. AlphaFlow finds it and reads the company by the measure built for it: Graham's defensive tests, owner earnings, sustainable profit growth. These are our rules in our words, written to those standards β€” not letters from those investors. β–  A checklist for the investor, not the stock Charlie Munger's habit was to invert β€” to ask what would make this go wrong. The checklist puts four questions to you about your portfolio and eight about each company you hold, then keeps the answers. Next quarter it shows what you said last time, beside what changed. β–  The company matters more than the timing The buy-timing card reads moving averages, RSI and Bollinger Bands the textbook way β€” and says so on the card itself: rather than timing a purchase, it is far better to find a good company, buy it early and hold it for years. That is why this app shows no ticking price. β–  Also inside Β· Undervalued companies β€” cheap against the cash they should earn Β· What the great investors hold β€” from 13F filings Β· Alpha Notes β€” company stories read through earnings and industry shifts Β· My Stocks β€” news, earnings dates and scores for companies you follow Β· Investing basics in short, markable reads β–  Subscription Every number stays free. AlphaFlow Pro is an auto-renewing monthly subscription. It removes ads, lifts the ten-companies-a-day viewing cap, and triples how much new AI analysis you can run each day. The price is shown in the app before you confirm. Payment is charged to your store account when you confirm the purchase. It renews automatically for the same price and period unless you cancel at least 24 hours before the current period ends. Manage or cancel anytime in your store account settings.
