Pros
Pro Textures the model
Pro Uses high power servers
The fact that it's not your phone actually processing everything by itself means you will get much faster and more accurate results as the phone is not doing the heavy work. This also means that just about any device including low end ones can take advantage of the app.
Pro Textures the model
Does a pretty good job at texturing the model.
Pro Great interface
The interface is very user friendly, and offers some great options such as being able to re calculate a 3d mesh from an already taken set of images, and easy model management. It also feeds beginners with nice little useful tips.
Pro Works offline
Unlike many other competitors, Scann 3d does not send photos to an online super computer for processing, but rather uses your phones own prossesor. This means that you can make 3d scans anywhere, whithout using gargentuous amounts of bandwidth and/or mobile data.
Cons
Con Uses internet
The fact it uses online servers means you will end up having to send them a pack of high definition pictures, using up a users data. This also means the app will not work if there is no internet connection at the time of use.
Con Requires taking many photos from specific angles
This can be difficult to do depending on what is surrounding or near the object you are trying to scan with numerous photos.
Con Models are not that good
As is to be expected, the models that come out from this application are not amazing. The program also has the nasty habit of merging the ground in the model, which makes it hard to take small objects as scans.
