Scanner, Charts & Option Odds
$3.99 · Designed for iPad. Not verified for macOS.
Now with the option Greeks, SEC insider filings and the levels a stock actually turned at. Your brief across 12,000+ stocks & ETFs, ranked by expected value.
The whole US market, one lens. MarketLens opens to a brief on what changed — for the names you follow and for the market — then hands you the tools to dig in.

• Share any screen as a card — every one states what its numbers are
SEASONS

THE HONEST PART
MarketLens is a screening and research tool, not a broker and not an advisor. Every probability is a labeled model estimate. Quotes may be delayed, and community-mention data reflects chatter, not analysis. Nothing here is investment advice; always do your own research.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Reading the chart from the bars themselves, the option Greeks, insider filings from the SEC, and a lot more control over how the app looks.
THE CHART
• The chart now leads a symbol's page instead of sitting under a screen of numbers
• Volume under every chart, coloured by whether the bar closed up — and volume by price alongside it, showing where trading actually concentrated
• Levels the stock genuinely turned at, with the number of times it happened printed on each one. Not a formula on yesterday's range
• A plain-English line under the chart: uptrend or downtrend and since when, where price sits in today's range, whether it gapped and whether that gap filled
• How the name is moving against the S&P and its own sector. A stock down 1% on a day the market fell 3% is ahead, and it says so
• Unfilled three-bar gaps drawn as bands, filtered so the ones shown mean something
• Chart controls now sit on the left, so they stop moving when the number beside them changes width
OPTIONS
• Delta, gamma, theta and vega on every contract, computed on-device from the same inputs as the win estimate
• A reference covering six structures and which Greeks each one is exposed to
• Every calculation now uses the live 13-week Treasury rate instead of a fixed 4%
• A setup in Top Picks opens the ticker itself — chart, stats and news — with the chain one tap further in
• Top Picks opens at 70%+ rather than 80%+ — more of what the scan actually found
FROM THE SEC
• Insider Form 4 filings on any stock, with the transaction type named. An open-market buy and shares withheld to pay tax on a grant are not the same event
• Sales made under a 10b5-1 plan are flagged as scheduled in advance
AROUND THE WORLD
• Which of six major exchanges are trading right now, in their own local time. New York and London carry a countdown; the others show hours only, because their holiday calendars can't be computed honestly
MAKE IT YOURS
• Ten backgrounds: the four seasons, Auto, Classic, and four that make no claim about the date — Slate, Sand, Rose and Midnight
• All the seasonal washes are calmer, so the background stops competing with what's on it
• Card transparency in six steps, from Solid through Gradient to Clear. The app defers to iOS's Reduce Transparency setting over its own
• Six app icons — the same mark in blue, green, violet, teal, rose or amber
• A new icon: a price tape read through a lens, replacing the green line and magnifying glass
ALSO
• 160 tips, including settlement, assignment and what the Greeks actually mean
• The ⓘ now teaches: each screen's card carries a rotating tip from its own subject instead of the same sentence every time
• Every screen shares as a card, each stating what its numbers are on the image
• The ETF holdings list folds away, like sector weightings below it
• The tab bar now takes the seasonal accent too
