App looks nice (can't check it out, no iDevice). I like the simplicity of it. Do you plan on adding any vision capabilities, like auto-detecting rectangles as candidates for buttons, circles as candidates for radio buttons, etc? I can also see you app used to make quick&funny games, which you can send your friends. Think taking a picture of a street, with a bar door as a button, and then taking a picture inside, making the bartender a button, then a picture of the drink, etc...
We don't have any image recognition stuff coming or pre-made elements but we are adding transitions/animations so that you can get a sense of what your apps might feel like.
Very nice! It took me roughly 2 minutes to upload the sample photos I had on my dropbox account, and link between them like a little game. Very intuitive interface.
A few friends and I experimented with this at a hackathon a few months ago. Check out a video demo at http://youtu.be/9ZAbQi_8y_A. Note: the OCR is mocked.
