Dropbox sync enables design teams to keep using the tools they love, like Photoshop and Sketch, while working together in a shared Dropbox.
Design teams use Dropbox because it makes working together simple. There's no second guessing on the latest version of a file and anything saved to a shared folder is instantly updated on everyone's devices.
Update the color of a button, the font of a headline or retouch a photo. Simply export your design assets in Dropbox and see Proto.io update automatically, keeping all of your interactions and animations intact.
Finally, an easier way to organize your design assets -- in folders, in your Dropbox the way you like it.
Proto.io is used by some of the best companies in the world
