App Card

The App Card is a great way to represent mobile applications on Twitter and to drive installs. We designed the App Card to allow for a name, description and icon, and also to highlight attributes such as the rating and the price.

The Tweet below from Jason Stark (@jaysonst) shows an App Card (photo and text) below the 140 characters:

This Card type is currently available on the twitter.com website, as well as iOS and Android mobile clients. It is not yet available on mobile web.

Our system recognizes when URLs are included in a tweet, and crawls your site to fetch the Card type and content. To learn more about how our Card system works, read our Getting Started Guide.

Sample Code

Adding an App Card to your tweets is as simple as adding the below meta tags to your site:

<meta name="twitter:card" content="app">
<meta name="twitter:site" content="@TwitterDev">
<meta name="twitter:description" content="Cannonball is the fun way to create and share stories and poems on your phone. Start with a beautiful image from the gallery, then choose words to complete the story and share it with friends.">
<meta name="twitter:app:country" content="US">
<meta name="twitter:app:name:iphone" content="Cannonball">
<meta name="twitter:app:id:iphone" content="929750075">
<meta name="twitter:app:url:iphone" content="cannonball://poem/5149e249222f9e600a7540ef">
<meta name="twitter:app:name:ipad" content="Cannonball">
<meta name="twitter:app:id:ipad" content="929750075">
<meta name="twitter:app:url:ipad" content="cannonball://poem/5149e249222f9e600a7540ef">
<meta name="twitter:app:name:googleplay" content="Cannonball">
<meta name="twitter:app:id:googleplay" content="io.fabric.samples.cannonball">
<meta name="twitter:app:url:googleplay" content="http://cannonball.fabric.io/poem/5149e249222f9e600a7540ef">

**Note**

Platform-specific URLs are deep links into your app. If you do not support a particular platform, omit tags for that platform from your website.

**Note**

If you have an iPhone app, but no iPad-optimized app, you may want to include the iPhone app id, name, and url for both iPhone and iPad-related tags. If no value is provided, the Cards will simply render a “View on web” link pointing to website of the card.

How it works

The App Card is unique, as we use each of the respective app stores (Apple iTunes, Google Play) to proxy the pertinent Card data. If you specify the Card type, and each of the corresponding App IDs to the respective app stores, our system will proxy the rest for you (# of reviews, # of stars for the app, etc.). You also can optionally specify a more concise description of your app.

When testing your App Card, make sure that the app is publicly available in an app store, otherwise we will not be able to pull its information. By default we search the US store, so if your app is in a different country, be sure to define this with the twitter:app:country meta tag.

The image for the App Card is also downloaded directly from the app store on which your app resides. To ensure your App Card works properly, the image uploaded to the iTunes/Google Play store must be less than 1MB in size.

App Downloads and Deep Linking

In addition to driving downloads, the App Card can allow you to deep-link from this Card into your mobile app. Learn more by reading Cards for Mobile Developers.
