I'm a bad troll...
Soooo... outside of an awesome name, I'm not seeing the difference here, sorry boys.
Well, Tinder is the surrounding area and meetings//encounters//etc often occur surreptitiously and you can keep them as contacts. This would be more "one offs". A quick encounter to "celebrate" a victory, because after the game, all your contacts from the game, would go away.
I'd say, the difference between Tinder and DTP, would be akin to the difference between Instagram and Snap Chat.
