BUSTLE - Aug 29 - Pure is a much-hyped new app that promises a "quick and safe way to find sex right now." The app was launched by two San Francisco tech entrepreneurs Alexander Kukhtenko and Roman Sidorenko. The app works just like Tinder and Grindr. Users log in, create a basic profile and the app pulls up potential matches in the vicinity. The Pure difference is there's no pretense of non-sexual use.
