The big difference between Fotowoosh and Make3D is the web site. Fotowoosh is implemented as a Facebook application (!) that renders a movie where the camera moves in a preset path around the 3D model. Make3D instead lets you move the camera around freely, and also allows you download the 3D model in VRML format so you can import it into a 3D application and actually do something with it. It is also possible to "fix" an image by drawing the planes by hand, helping the Make3D algorithm do its job. I wasn't able to improve the results with this functionality.
It will be interesting to follow the future development of these applications. Currently they are still a curiosity with limited use, but hopefully the algorithms will be improved and we'll get useful results.
