Benefits:

• You can use your existing C5 skills to build it.
• Unlike native apps, you only build once and can deploy on multiple handsets (eg. iPhone, Android, Blackberry, etc)
• No need to wait for approval from Apple to publish mobile app - instant deployment.
• Central installation (unlike downloadable apps), so you update once and all users access the latest version
• Users can add a "bookmark" to the mobile device home screen. The icon can be customised along with a "loading" screen. When a web app is run.
• From the "bookmark" it opens in a full screen browser and looks just like a native app (no browser navigation buttons).

Features:

• Works on all mobile devices including iPhone, iPod Touch, iPad, Android, Blackberry, Windows Mobile. (Any device that uses a mobile web browser compatible with Webkit. For non-Webkit browsers, some page transitions may not work.)
• Custom block templates for popular blocks: form, guestbook, image, login, next/previous, pagelist, rss, search and Youtube. So these blocks look just like an iPhone app.
• BONUS mobile gallery block included which looks just like the iPhone "Photo" app, with swipe action to navigate between photos.
• If you are experienced in development with C5, you can create your own block templates for almost any other block.
• AJAX page loading supported (using a custom page attribute).
• You can easily add a "back" button (using a custom page attribute).
• Preload selected pages for super-fast loading times and transitions between pages (using a custom page attribute).
• You can easily hide the toolbar for a specific page (using a custom page attribute).
• Automatic display of animated message encouraging users to "bookmark" the web app (add to home screen).
• Preliminary support for iPad optimized interface. See a 2-pane layout on an iPad device and automatically see only 1 pane on an iPhone - no need to change your site content.See demo. Additional features will be built on this in upcoming releases.

Limitations:

• Since the web app runs through the mobile browser security is inherently stricter compared to a native app.
• The web app can't take advantage of some hardware features (like camera, accelerometer, etc). The only hardware feature compatible with mobile browsers (and HTML5) is the GPS - which is useful for making a map-style app.
• Although mobile web browsers try to do everything that desktop web browsers do, they just can't.
• Hardware processing power on a mobile device is far less than a desktop, so be cautious with processor-intensive scripts (such as jQuery animations, slideshows, etc).
• Mobile apps tend to be more simple in structure compared to large websites, so use the "keep it simple" rule when building with this theme.
