I'm deeply committed to my iPhone, but never download apps without a glowing recommendation from a friend or relentless begging from my kids. That said, every app I have is used frequently and falls heavy into the "Mom app" category. I honestly don't know what we did before smart phones. But I suppose at some point in the early '90s I said to someone, "I honestly don't know what we did without pagers."
1.) Best Camera is a photo app you can use to apply different effects--lightening, cropping, colorizing--to your iPhone photos. This is my most used app, by far. I use my camera on my iPhone daily. The most frustrating thing about iPhone photos is they can come out too dark--Best Camera can take care of that for you on the spot! Here's an example of what else Best Camera can do for you.

2.) Angry Birds is a game app. I really would like to recommend this app, but be warned--it's addicting! My daughter, Emily, even made this comic about my love of Angry Birds.
3.) Hipstamatic is another photo app, but this one adds instant nostalgia to your iPhone photos. Hipstamatic gives me the ability to be creative during even the most mundane errands or simple moments--I love that! Check it out.
4.) iHandi Tip Calculator. This app will not only noodle your tip for you, it will also split the check for you.
5.) Pandora is a free music channel streaming app that will play customized play lists for you on your iPhone. I plug my iPhone into the speakers in the kitchen, then select an artist and let the Pandora create the soundtrack to dinner or homework time. Nothing like a little Clash mix to help me through beef stew and vocabulary words.
