For many modern, tech-savvy collegiettes, smartphones have been acting as personal assistants for years now. But with their huge databases of apps, they can also be trainers, teachers, weathermen, stylists, and even beauty consultants. Maximize your smartphone’s potential by checking out these seven beauty apps (best part is, they’re all free!). Next time you’re in a beauty sitch, you’ll be glad you did.

1. When You’re Applying Makeup On-the-go:

Mirror, mirror, I have none…What to do for a girl on the run? Yes, ladies, there’s an app for that. Mirror, rather than simply providing a reflecting screen, takes advantage of the front-facing camera on new iPhones to create an experience that more closely resembles a real mirror. Unlike the regular front-facing camera, this app won’t flip your image, making your beauty routine on-the-go that much easier! You can even freeze your image within the app for a closer look. If you’re a collegiette with a Droid, try the likenamed “Mirror” app for Android. It allows you to control exposure and zoom all within the app. (iPhone)
