Genius Scan

Genius Scan is an app that could be extremely useful to you.  It is a scanner app that allows you to digitize anything.  SO, for example, if you have a worksheet that you would like to send home electronically, you simply take a picture of the worksheet with your iPad and it turns it into a PDF that you can share any which way you would like.  You can email it, print it, upload it to Dropbox, upload your document to Evernote OR if you download the free GeniusFax app, you can fax it from your device!   For a super quick demonstration about how it works, click here.

Best of all, it's free!
