Dice rollers for Android?

[Arutema]

As I get into higher-level play, I am beginning to find it impractical to roll and add up 13d6 or 18d8 by hand. Thus I turn to my do-everything smartphone. Can anyone suggest a dice-roller for Android that can roll and total a lot of dice quickly?

I just searched "dice roller" in the Google Play app store on my phone and there are a bunch of options to choose from, most of them free. Go see which one you like the best.
