DIGITAL TRENDS - Nov 8 - New dating app 'Pure' is more focused on hookups than Tinder. Users don't have to link their Facebook account to Pure. Their presence on the service is minimal. Users photo and information is only hosted on the app for an hour at a time; then it's all wiped away until they make it available again. First five attempts to hook up are free. If Pure gets one thing right, it's the privacy factor.
