Why you want it: This app is a digital version of real-life adult sexy dice. Think of it as strip Yahtzee…or something like that. There are several dirty digital dice apps out there but upon investigation, we decided the Spice Dice app from Durex (yes, the condom makers) was the most interesting thanks to its fun categories: Romantic, Foreplay, Sexual or Kinky. The “Romantic” options are very tame. “Foreplay” gets a little saucier. “Sexual" starts getting steamy with position how-to’s. And “Kinky”? Our first two rolls were “Oral in the Shower” and “Video Al Fresco.” Now we’re talking! Go ahead, shake your iPhone to activate the app and you might just rattle and roll.
