I've been obsessed with apps for my iPod Touch (essentially an iPhone without the phone). Mostly free ones but anyway I wanted to ask what your favorite apps are if you use an iPhone or iPod Touch. You of course can post Droid apps here too.

Here's the list of the ones I use:

Free -
Urbanspoon is a great app to help you decide where to go out to eat and also gives you lots of information like hours, an idea on prices, and locations. Urbanspoon example

Buddy Rush is a free rpg game you can play on your iPhone/iPod Touch as well as on Facebook. It syncs both ways, and is pretty fun. You will either have to pay or install useless apps for free 'chips' to get better upgrades and characters though. Buddy Rush gameplay (identical on Facebook)

Pocket Legends is another free MMO RPG that plays similarly to WoW. The characters are limited though - a bird archer, a bear warrior, and an elf mage is all you really can choose from. But the game is pretty fun anyway. Pocket Legends gameplay

Wa Kingyo LE is a free little app where you play with goldfish.
