Kinetise is another option you might find interesting. The Wordpress plugin is only one of its many features - you can get and send data, including pictures or GPS coordinates, use maps, videos, web pages… You can make fully functional apps without writing a single line of code, and they are purely native. You can try the editor without even registering (and download an test app on your phone as well, it will just expire in 24 hours if you don’t upgrade it), so give it a try.
