I use an android application called Pack Of Cards https://play.google.com/store/apps/details?id=azurewing.packofcards&hl=en
It shuffles a deck of cards. Allows you to go through the deck multiple times, then allows you to re-shuffle etc. Definitely one of the better applications to practice with!!
You're Welcome! :D
