I have several of the apps. And an iphone, don't know about android. Here are some observations:
Mousewait: As far as I can tell, Mousewait only has "reported" wait times. This means that someone currently at the park has to input the wait time they just saw. Great, but if no one has reported a wait time in the last 1.5 hours, the data is not relevant. Right now, for instance, I'm typing this at 7:10 PM. RSR's wait time is from 6:46, GRR is from 6:09, ToT is from 7:05, Alice is from 6:14 ... you get the message. I don't really care at 7:10 what the wait time was an hour ago.
Lines is from Touring Plans. They show current posted wait times (I'm not sure where they get these from), along with an "expected" wait time of how long you should actually expect to wait. For instance, they're showing Alice at posted of 30 and expected of 25. The "expected" wait times are based on their historical projections. In addition, you can also look at submitted wait times. The downside here is that they aren't nearly as many people submitting on Lines as on Mousewait. Alice, for instance, hasn't had a wait time submitted since 8:36 this AM.
One thing I do like about Lines is their menu function. Not only can you browse menus, you can search for a particular item. Churros, for instance.

Returns a list of 16 different places you can find one. (I have the paid version; not sure if this is on the free one.) I would buy Lines for this function alone!
You can also create a touring plan either using Lines on your phone or on their website. If you create it on their website, it downloads to your phone. Comparing their custom touring plans to Ridemax -- Lines/TP seems quite a bit more optimistic about the wait times.
Ridemax doesn't have an app and doesn't show current wait times. But you can create a custom plan, print it out, and take it with you to the park. I've found their plans work well, but definite points off for no app.
Finally, you can always call Otto for free. 714-520-7090. It's updated by DL, but I don't know how often. I can say that it's very quick and easy to use. When I called at 7:10, it also gave me a wait time of 30 minutes for Alice. No touring plans, though.
Good luck and have fun!!
