Cell phone picture to pdf

In one of my magazines it talked about using your cell phone as a quck scanner with the aid of an app.  Here are the apps it recommended:

Free:
Apple- Genius Scan
Android- ScanToPDF

They will crop, resize, color adjust, and convert to a pdf for you.

Paid:

Apple- TurboScan ($2)
Android- CamScanner ($5)

They will let you print, text, email, your pdf files, and they won't "flood your cell with ads like some free apps can.
