If you just can’t pass up a good word game, Danilo Campos’ Oddage is the one for you. With this app you need to pick out the word that doesn’t belong with the other ones. Categories include periodic table elements, county names, spices, Greek gods and trees. There are a total of 900 words in 50 categories, and each game lasts between 60 to 90 seconds. The download is $2.99. We guess this is a perfect application while waiting for the ATM or the idiot in front of you that has more than 10 items in the express lane.
