Are you into online dating? If so you'll be pleased to hear that there is currently a third party Tinder application in the BlackBerry Beta Zone called Dater.
Now I must admit I've not used Tinder before and don't really know too much about it, although I have heard friends mention it who use an iPhone or Android device.
According to the developer of Dater the application is still in its very early stages and at the moment just allows you to check out the user interface - which looks real hot. In addition, the UI isn't optimized for the Q devices, although it looked just fine and dandy on my Q10.
If this looks like your sort of app download it for your BlackBerry 10 device and provide the dev with feedback.
This one looks very promising to me.
