Camscanner is good app for any type of document scan , auto set size according to document size.all over performance is good and easy share scan documents.i think it is good app for in emergency scanning any type of document.
It is very useful but some times I faced hang problem for scanning and slower loading.better option and many other feature also available.dicrect sending option is best .it can scan same and good clearity of document.it have two option make '.pdf' and '.jpg' extension for save scan documents.
