Hot Lava, which was recently acquired by OutStart, is now offering a free version of their m-learning development tool. It is accessible at this link, Hot Lava download-registration. Here is also a description of Hot Lava.
It is a full version and without any time limitations. My guess is that OutStart will be making significant improvements to the software, so why not offer the current version free as a teaser. If you are interested in creating m-learning, here is a free tool to get you started.
