Overall I think lumapps has great potential, it surpasses the capabilities of other options, and provides advantages over using google sites. That said, I'm somewhat disappointed. The trial version is very limited, most of what you see in the demo videos and screenshots is not available in the trial version, as there really is no way to test or get an idea of it's functionality. I"ve tried several times to get ahold of lumapps, to inquire about pricing. There is no info on their website, and they do not respond to their emails, and requests for more information. Overall I think it could be a good app, but they really need to work on their customer service/sales/support. I tried several avenues, and sent several different messages in an attempt to get more info, but had no luck, I'm uncertain if this is still in development or they are not ready to sell licenses, but at least I would have liked a response to my questions. I would have to recommend something else.
