Bloons Tower Defense 4 (iPhone/iPod Touch)

 is Bloons TD 4 for the iPhone and iPod Touch. The icon has the Mortar Tower on it. The iPhone/iPod Touch version of Bloons TD 4 is very similar to the online, flash version of the game, and has the same choice of towers, the same upgrades, and the same ranking system. You can also save your game without a mochigames account.. Unlike in the flash version, you can save your game DURING freeplay mode, so you can exit freeplay mode and still continue from the last round finished.

A major disadvantage is that you can't resume your game when you get a game over, unlike the online, flash version, so you can't repeatly attempt a roud that you cant pass.

on 5/17/12, they added a new tower as an update which you can unlock for popping 2000000 bloons.
