I really like pubcoder. I actually use it more for fun to build apps with my kids. I hope to learn more and eventually use it for other things. It is possible to also download the pubreader app for phones and then send the project to them so it is kind of like a little app we added to only the phones or ipads we sent them to. If creative you can do a good amount with it. My kids favorite is the matching game and now he has become pretty good at matching games among groups even with physical cards. I like the UI, there are features I wish it had but I also suspect I may need to just learn more.
