Development platform appMobi has already unveiled its HTML5 accelerator DirectCanvas, which is claims will speed rendering by up to 500 percent.

Now, with the launch of two new JavaScript frameworks, the firm has turned its attention to user interfaces, offering developers what it claims are the tools to spruce up their HTML5 releases for iOS and Android.

Covering all bases

It's all part of what appMobi brands as its long term effort to accelerate the industry's move to HTML5, with the two UI libraries – available without charge – covering everything from neat visual touches like transition animations to more practical elements, such as list scrolling.

"These open source JavaScript frameworks will help anybody who wants to create great mobile apps using HTML5, even if they are using other development tools," said CEO Dave Kennedy.

"AppMobi placed its bet on HTML5 as the unifying technology for mobile in 2009 and we welcome all developers to the party."

Aiming aUX at UI

The first of the two appMobi User Experience (aUX) frameworks on offer, dubbed aUX.js, is aimed at developers already working with the appMobi platform.

In particular, the library focuses on the delivery of touch-based gestures and inertial scrolling, for both native or web-based apps.

The second library, known as aUX_web.js, can be used by developers not yet tapped into the appMobi network, specialising in password entry, multi-button selection and carousel selection.

Both frameworks are available to download with documentation from the appMobi GitHub code repository.
