There are few Tamagotchi apps out there, but this is the first one I’ve seen that looks and feels like the original.  All the way to the grey bit graphics. The app is called Hatchi and from what I can tell, its going to be almost exactly like the original, and just as time consuming.:)  As if playing with your iPhone is not addicting enough.

Its only ~99c, so if you have played Tamagotchi is the past, or wish you did, well here you go.

Update, after two weeks mine died.  It evolved 3 times but nothing after that.  Well, fair enough. Would be interested to see a few new features after awhile.
