Disney iphone apps

Hello all!

I'm looking for recommendations for good Disney iPhone apps. I've downloaded some of the freebies that have info on wait times, park hours, dining, etc. There are tons of Disney apps out there...which ones are the best? Which ones are worth paying for? We're heading to Disney on 5/28 (the kids don't know...it'll be a big surprise!) so I'm hoping to get all my apps downloaded and tested out before we leave. Thanks much!

On Android, I love Touringplans.com's lines app. You do need to join, but it kicks both Ridehopper & Ridemax's butt.

I don't pay for any apps (well maybe Angry Birds....) but here's what I've got in my Disney iPhone folder:

WDW Maps
WDW Waits
WDW Hours
Undercover tourist (free version)
StarTours 2
WDWMagic's app

Based on my last trip, the wait times are accurate enough for gub-ment work.
