Many authoring tools can deliver content to mobile devices. The tools provide this capability by using a mobile device screen template and output files that work with the mobile device operating system. 

However, tools are emerging that are specifically designed for mobile learning; for instance, providing authoring capability for audio learning content (e.g., spoken word, podcasts) along with associated interactive assessments and surveys. Other tools are optimized to provide e-learning content through the phone's web browsing capability.

There are several e-learning content authoring tools on the market that offer a mobile-friendly output version of your content. However, some of them are designed to run within their own platform and stand-alone portability isn't always possible. Some of these support SCORM output. Some of the tools that we've seen only target one screen size. This is not a definitive list of all types of mobile tools, but serves to provide a starting point for investigating tools that support learning delivery.

The ADL Mobile Learning Team is currently collecting information on available tools from vendors. Responses to date (27 July 2011) include 36 vendors in the spreadsheet and PDF files below.
