Yes its been there for years in foreflight, however, it does not replace flarm in thatvit doesnot use algorithms to inhibit alarms to traffic you are not going to hit. In other words all traffic within 200 feet altitude and 1 mile will be displayed as a "risk" even if you are flying in the same direction and at the same speed. Flarm uses the aforementioned algorithms to filter these target out and only "Alerts" you to ones you are on a collision course with. IE if your all behaving well in a thermal = no alerts where as foreflight with Stratus ADSB in would alert you to everyone in that thermal making it useless. Hope that helps!
