Jenna Haligas uses her phone for just about everything, including voice recordings of her children.
"I'll say, 'Hold on, hold on' and I'll have 'em, you know, record it and I can download it to my computer and I'll always have it," she said.
The free app to that came with her phone. It's part of a large market of phone applications aimed at women.
"You're seeing a huge explosion of applications because iPhone is the first smart phone that really appealed to mainstream women, not just techy women," said Molly Wood of CNET. "And so I think people realized there was a huge market there and they better get some apps out the door."
It's not just iPhones. Many smart phones have apps women can find useful.
"You have this new category of calorie counters and those are really useful for women," said Wood.
Livestrong's calorie counter lets you enter what you've eaten that day, along with how much you've exercised.
Jenna uses FoodScore to keep track of points for her diet, even at the take out line.
"I can just go to my app, I can scroll through and pick a dinner based on the points and know what I'm eating instead of having no idea, you know, how many calories I'm taking in or how many points I'm eating," she said.
The Grocery Gadget app keeps track of shopping lists.
"There's a little tutorial here that kind of walks you through how to create a grocery list," said Wood.
"There's a great app for Gilt, g-i-l-t, which is an invitation only Web site that has designer sales. So, say you've been eyeballing Michael Kors or waiting for an espresso machine to go on sale, you can actually get a notification right up on your phone," said Wood.
A high end app puts Chanel at your fingertips.
If you're a new mom, the Emmbook app keeps track of growth measurements, feedings, diaper changes and immunizations.
For older children, there's the simple Shape Writer, a high tech doodle pad.
"You're in the grocery store, or you're shopping, or just even talking to another adult and it's just nice to keep their attention while you're doing that," said Jenna.
The cry translator app claims to help identify the distinct cries made by infants when they are hungry, tired, stressed, bored, or annoyed.
