Perhaps the best free iPhone Twitter client on the market, TweetDeck is quick, has a nice and easy-to-user interface, gives you information about the number of updates right up front, and supports all of your basic Twitter functions. As an added bonus, TweetDeck also supports Twitter groups, so you can organize your tweets. Flipping between sections is easy, and the fast scroll of tweets is nice when flipping through updates.By offering free versions of the game, the developers can then run advertisements that display between rounds and/or at the bottom of the screen. Unless the app has had significant downloads, there isn’t much traction in the way of impressions or views of those advertisements, so the money that they generate is paltry, compared to the number of hours they have invested in the product.
