Scan Page (Free)
By Ricoh Innovations
Unlike other scanning applications, this one doesn’t put just camera to use. After capturing the image, it allows users to select the document area they wish to scan and gives an option of auto-clean up. The autoclean up converts the captured image to look like a scanned one. Images can either be saved on the device or exported via email, Dropbox, Evernote or Google Docs. A must-have app.
