For those of us who avoid the malls most of the year, the FastMall app helps find things inside the mall with turn-by-turn directions. It guides you to specific stores, the escalator and the food court.
A fun bonus for iPhone users: Shake your phone to find the nearest restroom! And especially handy during this busy season, it offers a parking locator to help you remember where you parked the car.

In these rough economic times, price scanners can help you save money - or at least help you decide faster whether an item is worth buying. The RedLaserapp, from eBay, scans eight types of barcodes and pulls up comparable prices to retailers online and at local stores (the latter powered by Milo.com and TheFind).
Beyond Black Friday, the app helps you track down books at the local library or see if a certain food at the store will cause allergies.

The hustle of holiday shopping could leave your phone vulnerable, so use an app to help protect it. Make sure you turn on "Find my iPhone" on your Apple-iCloud connected device, but there's also the new Lookout Mobile, which is popular with Android users.
You'll be able to locate the missing phone on a map and sound an alarm even if it's in silent mode. It'll also show whether the Wi-Fi connection is secure and back up contacts online.

Also notable: The GadgetTrakapp can be activated online after the phone is lost or stolen and tracking begins immediately. It'll even snap a picture of the unsuspecting thief.
