You can also perform the same functions with an Android phone and Evernote. See http://goo.gl/ekDILO for details.
You can also use the same techniques with an iPhone and with Dropbox. Assuming you have the Dropbox app installed on your iPhone, open the Dropbox app on your iPhone, tap the + (plus sign) button, and choose Scan Document. The iPhone takes a picture of the document being :”scanned.” After scanning the document, the next screen is the Edit view. The icons on the bottom of this view represent the actions you can take to edit your scan. Finish your editing and then tap Next to enter the Settings view. Name your file and decide on a file type and then decide where to save your document. Finally, touch SAVE.
With the iPhone and the Dropbox app, you can also save scan up to ten pages of a document and save the file as a single .PDF file.
