There are over 20 Apps for levels in the App Store.
The problem with the App levels is that they all need calibrating. So who has a 100% level surface to do that on? They might get you closer than a regular carpenters bubble but from what I have read in the reviews they are not close to the accuracy of a dedicated tool.
