Vlingo (for us iPhone's without Siri) this app REALLY did change my life and works so well! Great for driving, or while doing your makeup.
Groupon, Amazon, and Living Social. I check all nightly. There really are some AMAZE deals on Groupon. I admit, I am so addicted I buy probably twice a week!
Fandango. Best, and easiest app to check movies, movie times, watch trailer, and even purchase tickets. We use this app ALL the time!
Food...Table. A meal planning app that I haven't really explored too much, but it looks so helpful. I WILL start using it soon.
And in my "Photography" section my favorite are Camera+, Vintage Cam, Instagram, Pic Collage, and PictureFrames. I am a picture taking FANATIC! I use all of these multiple times per day.
I am not even going to get into my "Kid, Toddler, or Games" apps...that's a whole other post right there. So if there anything that I'm missing? What are some of your cant live without apps (only iPhone users please, sorry android- you drool). Hee hee I kid...I kid...not really..
