TOM'S GUIDE - Feb 19 - The Date Check-in feature is the latest safety measure for Match Group's dating apps. With the Date Check-In on Match.com, users are able to let people know they're on a date and to send them an SOS if they're feeling unsafe during the date. Tinder added a similar safety feature last month. In the case of Tinder, the safety features tie into a separate Noonlight app that also provides a panic button for alerting people when they feel unsafe.
