can you activate a xFi Pod without the app?

I'd like to get an xFi pod to try out in my house.   From what I can see, it says you activate it with the xfinity app.   However my xfinity app has never worked for me, every time I try to log in it says "Sorry, that didn't go as planned".     I tried thee app on my iphone and ipad and it doesn't work. 

Can I link up the pod using the WPS button on the back of my white XB7 gateway?
