I have been using Corona for 12 months for business Apps and it is excellent. The only issue is text input, but following purchasing Widget Candy (which is not a great library if I am honest), it did however give the best idea on how to deal with text input more effectively. I have then adapted my approach for multi-line text input (which it did not support) so now I have all the tools I needed. Top tips for good business apps are:- start to build your own library of useful functions specifically for business. My library now contains functions to do your “typical” business type objects like drop down lists, combo boxes, boxed fields, yes / no switches etc. All of the tools are in Corona, but they are a bit raw - if package them up a bit it will make your life a million times easier. The other tip is keep on top of variable declaration and scope. You need to tidy up well when you leave a scene as lua/corona does not like objects in memory, especially anything with a scroll view. Finally, if data is going to be used, build a good quality HTTP library from the start to help with your DB comms…
