I loaded the app to my iPhone 6+. My iPhone is running the latest IOS updated version. Cant run this app. It crashes every time I try to authenticate into it. It looks like it would be a good app but so far its been a pretty bad experience. If they fix it where I can actually send a message, Ill rewrite this review but until then all I can say is buy it at your own risk... my experience is that it doesnt work.
