Anyone using iphone apps for carbs, etc?

I see that Livestrong.com now has an iphone app for The Daily Plate.  Wonder if there are any complimentary programs folks are aware of for entering units, exercise, bs levels, etc.

Thanks!

Log for LIfe works on the iphone, also Diamedic. both good diabetes programs for the iphone.

I posted about a couple of good iphone apps for diabetes. I will have to go through the forum posts to find it.
