Create Prototypes Using Dropbox - For Free

    Hey everyone,

    Marvelapp is a free mobile and web prototyping service for designers. It connects directly with your design files in Dropbox (PSD, PNG, JPG, GIF) and lets you add hotspots over the top to create a prototype.

    The reason why I made it was because I felt like all the other prototyping tools out there were difficult to maintain. Everytime I amended my PSD, I had to save out the PNG and reupload. Once you get to 30+ PSDs it takes longer than designing!

    It hit me one day - all my design files are in Dropbox, why don't we sync PSDs from there? That way every time you hit save in Photoshop, the prototype updates in real-time.

    So we did it! It's absolutely awesome for checking your designs, or doing design amends with clients. I recently chatted with a client on Skype whilst they had their iPhone in their hand checking my design changes as we chatted.

    We've built it to be quick, we can process a 4-5mb PSD in a few seconds.

    What it means is that showing clients designs doesn't need to take up dev resource, for agencies thats a big plus.

    I would really appreciate any feedback you have, this is our early public beta, we've got lots more planned so hearing your thoughts is really important.

    We're about to launch the new site but you can try it right now:

    Really love this app :)

    - I like the slide transition but need the opposite for when you hit a back button.

    - I think it would be better if when landing on a view you don't show the tappable regions. and in stead only show if someone taps and area that doesn't do anything.

    Cool man :)

    You should put links to a couple of sample prototypes with hotspots on the homepage btw.

    I now have to sign up to see what I get when I sign up, which is not very good for conversion.

    @Rick Waalders You're right, I've got a video in the new site as well as examples, the current one doesn't do the job at all

    Thanks man

    How were you allowed to use Marvel as name? Design looks great!

    @Josh Overton Yeah we don't compete with Marvel and there's actually tons of services called marvel in the UK - Marvel IT Services, Marvel Laundry, Marvel Computing etc so we're good we believe (hopefully!)

    Worse case scenario we'd have to change name (that would be sad tho!)

    Have you had a chance to try it?
