I have an iPhone4S and I have trouble with the pocket app. I go to the my.wgu website on my safari browser and it works fine/better than the app for me. Your mileage may vary.
Worked well on the ipad. I was able to toggle around in some classes, etc. It looks exactly the same as desktop/laptop. I just wish I could take it to work with me and use it there, but that's a big NO NO! Maybe when I do charge on nights in the fall for approx 6-8 wks...I might just take it then. No time on dayshift to even think about it, lol.
