There are a buttload of apps for the letter C.  A lot of good ones as well.  I could have easily made it 10, but i am keeping this to only 5 a day, which might not happen with some letters.  It's kind of like scrabble ya know.  

1. Crackle (Free)

A FREE movie/TV show app.  What is not to love about that.  A must have.  I would say its only downfall is that most of the stuff is at least 4 years old, but there is a lot of good stuff that old.  They also have some of their own content; Comedians in Cars getting Coffee is the highlight for me.

2. Crossy Road (Free w/ in-app purchases)

Although the game is super basic and gets old after about 5 minutes, it is still a lot of fun for that first 5 minutes.  The graphics are as simple as Nintendo, but that doesn't really matter.  What is most fun is playing 2 player and knocking you opponent into a train or car; it makes for a good laugh.

3. Comedy Central (Free)

Of course it requires a cable subscription, the app is everything Comedy Central has to offer.  TV shows, Stand-up, short form stuff like Drunk History.  No Live component, but the best TV app for Comedy there is.  Comedy Central has great programming, which is one reason I put it in the top 5.

4. CBS (Free w/ in-app purchase)

This is the only other app besides HBO to sell a service without having to need a cable subscription.  The price is way to much ($6.99), its still showing what the future of TV probably will turn into.  Hopefully Apple will let the buyer bundle 10, 20, 30 different channels for a cheaper price..but let the buyer pick the channels he or she wants.  That way every app isn't 7 bucks, which then becomes more expensive than cable.  There is Live TV option as well, but only for certain areas.  The only stinker is the on demand stuff comes a day later...LAME!

5. Channels ($14.99)

This is an app that accesses your local HomeRunHD DVR box wirelessly and stream from the content you have recorded on it as well as stream your cable stream live.  This puts everything in one place; the apple tv.  No need to use the clunky UI of your cable provider, no need to use their DVR box you pay 10 bucks a month for.  Although its not a perfect solution to TV, it sure puts more space between you and the horrible cable companies.  I champion this app only because of that.  The cost of the app is kind of retarded....and the UI isn't actually much better.  HAHA, but an A for trying!
