Really innovative

I haven’t been using it for too long, but this idea is genius. It is super useful and fairly well made.

My main suggestion is to improve the design abilities. The pen tool is virtually useless which is the biggest problem. I would like more icons available. There is no easy way to make a background besides making a large box.

Otherwise, this is super neat and I haven’t seen any ads so far!

Easy to get your hands dirty and start getting feedback

This app is very easy to use and makes it simple to get your ideas out of your head and into a format that you can easily share with people. It helps take the guess work out of setting up app development requirements. This platform saves time and helps you refine you iterate your ideas quickly.

Great Concept, Needs more APIs

As a designer this app is pretty cool. I can essentially give a working prototype rather quickly. As a developer, it’s lacking on APIs. Google Drive and other cloud storage (especially with open APIs) should have some time invested in them. Those alone will make a HUGE DIFFERENCE! I’d also try to partner up with Adobe’s Creative Cloud. And then try to add some hyperlink connectivity. If I could link these images to actual sites or html documents I could use this all day everyday.
