WidgetAIStock widget for iPhone: any ticker, a chart, your colours
Apple's Stocks widget shows a short list of symbols from the Stocks app with a small price and a coloured change. It's a decent default. What it isn't is yours: you can't make one ticker large, you can't add a real chart, you can't put Bitcoin next to Apple, and you can't change what "up" looks like. This guide is about building a stock widget that shows the symbols you follow, in the layout you'd design if you could, by describing it.
What the stock widget gives you
The built-in widget comes from the watchlist in the Stocks app. Small size shows one symbol, medium shows a few, with a tiny sparkline in the larger layout. The content and layout are fixed. If a compact watchlist is all you want, it's free and it works. Most brokerage apps ship a similar tile for your holdings, usually with the same rigidity.
The widgets people ask us for are more specific: one ticker in big type with a proper chart, a two-column tile of the three stocks they actually hold, a tile that's green or red depending on the day, or their stocks and their crypto on the same tile so one glance covers both.
Describe the stock widget you want
WidgetAI has a built-in stocks connector, so the data is available from the first message. You type something like:
"a small widget with the AAPL price, today's change, and a sparkline"
The AI builds it and shows a preview. Then you refine by talking. "Track NVDA instead." "Make the price bigger and the chart thinner." "Show the change as a percentage, not dollars." Each message reshapes the widget, and switching tickers is a sentence rather than a settings screen. Any symbol the connector recognises works; you name it and the AI rewires the data source. What's happening between your message and the widget is in how the AI builds your widget.
If you'd rather start from something, the Stocks template is a single ticker with a computed change, and Market Tape is a row of several symbols. Both reshape by chatting.
Charts, colours, and a few tricks
- A chart that's actually readable. A sparkline is the compact default. "Use a line chart across the whole width of a medium widget" gives you something you can read the shape of.
- Green when up, red when down. WidgetAI supports rules, which map a value to a colour. "Make the price green when the change is positive and red when it's negative." You can do the same for the background, or a small arrow, or the chart line itself.
- Your own thresholds. "Turn the whole tile amber if it drops more than 3% today." Rules take a range, not just a sign, so the widget can flag only the moves you care about.
- Several symbols. "A medium widget with AAPL, MSFT, and GOOGL in three columns, each with a price and change." This is the Market Tape idea with your own basket.
- Style it. Gradient backgrounds, a monospaced font for the numbers, a logo-free minimal look, whatever fits your Home Screen. "Dark background, white numbers, thin green line."
Stocks and crypto on one tile
Because WidgetAI also has a built-in crypto connector, the two markets can share a widget:
"a medium widget with Bitcoin on the left and the S&P 500 ETF on the right, each with a sparkline"
No single finance app does this, because each only knows about its own market. Building your own means the combination is one sentence. The crypto side has its own walkthrough in our crypto price widget guide, including switching coins and colouring by change.
How fresh is the price, really?
This is the part to read before you rely on the tile. A stock widget is for glancing, not for trading, and there are two reasons it can lag.
First, iOS decides when widgets refresh. You pick a refresh interval per widget, from every minute to hourly, but the system gives each app a limited budget of background refreshes a day and spends it on its own schedule. A stock tile can be a few minutes behind the market. We keep recent connector data cached with a freshness window that fits the source, so when iOS does refresh, the widget gets a current value straight away instead of waiting on an upstream call. The full explanation is in why your iPhone widget isn't updating.
Second, markets close. Outside trading hours the price is the last close, and the day's change reflects the last session. That's correct behaviour, but it means a widget that looks frozen on a Sunday isn't broken.
None of this is financial advice. Treat the number as roughly current and check your brokerage before you act on it.
Your portfolio, not just a price (Pro)
The built-in connector shows public prices. If you want your own holdings, your gains, or a symbol it doesn't cover, Pro users can add a custom HTTP API connector. Point it at any endpoint that returns JSON, a portfolio tracker's API, a brokerage export you host, a small script of your own, and bind the widget to the fields in the response. "Show my total portfolio value from the API and colour it by today's change." The full walkthrough is in custom HTTP API widget for iPhone.
Limits worth knowing
Widgets can't be tapped to open a specific ticker; a tap opens the app. They don't scroll, so a long watchlist has to fit the tile. They don't update in real time, and no widget app can promise otherwise, because Apple controls the refresh budget. WidgetAI builds small and medium widgets today, not large ones. The rest of the list is in what iOS widgets can't do.
FAQ
Can I make an iPhone stock widget for one specific ticker? Yes. Ask for "a small widget with the NVDA price, today's change, and a sparkline" and the AI builds it. Switching to another symbol is another sentence.
Can the stock widget turn green or red with the price? Yes. Rules map the day's change to a colour, so the price, an arrow, the chart line, or the whole background can go green when up and red when down.
Can one widget show stocks and crypto together? Yes. Bitcoin and a stock ticker can sit side by side on one medium widget, each with its own sparkline.
How often does the stock widget update? You choose an interval from every minute to hourly, but iOS decides when widgets actually refresh, so the price can be a few minutes behind. Outside market hours it shows the last close.
WidgetAI is made for iPhone, iPad and Mac, and it's on the App Store. The free plan gives you 1 widget and 10 AI edits a month; Pro adds unlimited widgets and custom HTTP API connectors as an in-app purchase. For more ideas, browse the best iPhone Home Screen widgets for 2026.
