Are you shopping on Black Friday this year? These apps will help you navigate (and survive) the madness.

TGI Black Friday
Free for iOs and Android
With the TGI Black Friday app, you can search more than 10,000 Black Friday deals across stores and categories. You can even receive push notifications the app when new deals are "leaked." See how many deals are offered at a particular store to better plan your shopping trip, and "save" your favorite deals so you don't lose track of it.

Black Friday Survival Guide

Free for iOS
Another type of deal app, Black Friday Survival Guide is great for organizing your Black Friday shopping list. See what types of deals are offered at each store and share your shopping list via email with friends.

TGI Black Friday and Black Friday Survival Guide pretty similar -- download both and see which one you like best (I mean, they're both free!)

SnapTell

Free for iOs and Android
Take a photo of a product you want to buy with SnapTell, and the app will tell you whether or not you can find it at a lower price online. Run by Amazon, SnapTell uses an image recognition database to see where the products are advertised online. The photos work best with books, DVDs, CDs and video games. You can also scan products' barcodes for more information.

Decide

Free for iOS
Unsure if you should buy that new flat screen TV? Now an app can help you decide. The developer says the app scours the internet for ads, blog posts and other information on appliances and electronics. Then, it predicts whether or not the product you want to purchase will increase or decrease in price.
