Finviz Heat Map on Your Phone: How to Use It (and What Works Better)
The Finviz map is one of the best-known pages in retail trading: the whole S&P 500 as a grid of green and red tiles, sized by market cap, grouped by sector. One glance tells you what kind of day the market is having and which sectors are driving it. It's free, and it needs no account.
The catch: there is no Finviz app (full story here), so on a phone the map is the desktop page scaled down. This guide covers how to make that workable — and what to use when it isn't.
How to read the map (30 seconds)
- Color: green = up, red = down. Deeper shades mean bigger moves.
- Tile size: market cap. Apple and Microsoft dominate their sectors visually because they dominate them in reality.
- Grouping: tiles cluster into sectors and industries, so a sea of red in one corner means the sector is selling off, not the whole market.
- Views: the toolbar switches between one-day performance, week, month, year-to-date, and more; other map types cover the full market, ETFs, and world markets.
Using finviz.com/map on your phone
It works — with friction. What to expect, checked September 2026:
| What you'll hit | Why |
|---|---|
| Tiny tiles | The map renders at desktop proportions; small caps become slivers you can't tap accurately |
| Tooltips misfire | Chart previews appear on hover, a mouse concept — on touch you tap and hope |
| Pinch-zoom everything | There is no mobile layout; the whole site sends phones the desktop version |
| Delayed data | Free Finviz quotes are delayed; real-time is an Elite feature at $39.50/month |
To make it feel more like an app, save it to your home screen: in Safari tap Share → Add to Home Screen; in Chrome on Android tap ⋮ → Add to Home screen. That gets you an icon, not a better layout.
Better ways to get a heat map on mobile
- TradingView's mobile app has native stock heatmaps designed for touch — tap targets that work, smooth zooming, and crypto heatmaps too. If a heat map view is specifically what you want in your pocket, this is the honest answer.
- Your broker's app (Webull, moomoo and others) usually has some market-overview view, though rarely as good as a true treemap.
The bigger question: what is the heat map for?
Be honest about why you check it: you're scanning for movement — which sectors are running, which stocks are breaking out, where today's opportunity is. The heat map makes you do that scan, tile by tile, every time you open it.
That's the part Finradar automates. Instead of you scanning a treemap for movers, its AI screens thousands of tickers — stocks, forex, and crypto — continuously, and when a high-probability setup forms it pushes the trade plan to your phone: entry zone, stop, targets, and the reason the setup formed. Every signal's outcome, wins and losses, is published on a public P&L calendar so you can judge the engine before paying anything. The free tier runs on delayed data, which is fine for evaluating it.
Heat map when you want the big picture; an AI screener when you want the shortlist. On a phone, the second one is the workflow that actually fits the device — download Finradar free on the App Store and compare it against your morning map-check for a week.
Quick answers
Is the Finviz heat map free? Yes — no account needed. Only real-time data and alerts require Elite.
Is there a Finviz heat map app? No. Finviz has no app of any kind; the map lives only on the website.
Can I see the Finviz map on my iPhone? Yes, in Safari — but it's the desktop version, so tiles are small and tooltips are awkward on touch.
What's the best mobile alternative? TradingView's app for a native heatmap view; Finradar if you'd rather have the movers found for you and pushed as ranked setups.
