The MobiRoller app looks pretty amazing. It allows you to create an Android app or iPhone app, by just using modules, templates and settings. There are modules for eCommerce, chat, connections to social media and other neat options.
I reached out to support for getting connected to their eCommerce Pro platform, and was able to work with them to get that started. It looks promising, and the product roadmap has all of the features I need.
My only complaint is that some of the examples are in Turkish, so it's difficult for me to see what the sample app is supposed to do. But that is minor, and does not detract from the good product or their good support.
