Mobile Magic?

It won't give you the attraction wait times and fast pass return times unless you are in the parks. For the most part it worked well.

I was curious about this. I used the free trial to try and get familiar with the ap, and for the most part I liked it, but I was troubled by the fact that every FP said 'unavailable' and the wait time always said 'see now' or 'moderate.'
So when you are in the park, does it actually give the return time for FP's, and does it indicate if they've run out for the day? That's what DH was looking forward to...not booking across the park to grab IJ FP's only to find out they're all gone!
