It’s hard to believe that a little device that’s the size of your hand can actually help parents become more organized, time-efficient, knowledgeable, even relaxed. However, that’s the beauty of an iPhone. The key, though, is to find the right apps to get you there, and with so many choices (more than 75,000), it takes time and effort to find good ones.

What follows is a list of 20 free apps that won’t necessarily make you a better parent, but can make your life a little easier, or help out in a pinch wherever you are. And when you have a screaming, bored, hungry, or need-to-use-the-bathroom kid, sometimes a little help is all you need. The apps listed below have been compiled from the eyes of a parent, but many can be used regardless of whether you do or don’t have children.

There are also several apps listed below that are ‘lite’ versions. These are completely functional, but just offer limited options compared to their more robust, feature-rich priced apps. What other great iPhone apps are you finding helpful as a parent? Let us know in the comments.

WebMD Mobile

WebMD’s iPhone app enables parents to look up symptoms and try to figure out what’s ailing their children. Of course, it shouldn’t take the place of professional medical advice, but for those cases when your child has a minor rash, fever, cough, etc., this is a great resource to try and narrow down what is going on, and prepare for a doctor visit if necessary.
