Sencha has introduced Space, aiming to make it easier for IT departments to manage HTML5 apps running on Android, iOS or BlackBerry devices. Sencha is best known for its cross-platform development tools designed to let users create customized HMTL5 apps for PCs and mobile devices. But as more enterprises allow users bring their own devices to work, there is an increasing need for a tool that manages these apps, the company said on Tuesday.
