Fresh Pantry (iTunes) and Food Expiration Track (android). These apps helps you manage expiration dates on products you buy, so you know what you have, how long you've had it, and when to hoe it out of the fridge or cabinets. Simply take a picture of the product, enter the expiration date on the packaging and the app takes it from there. You can see what you have in stock and receive notifications when they are nearing expiration. The apps can also be used to keep track of medication, coupons and cosmetics. Fresh Pantry is $0.99 in iTunes, and Food Expiration Track is free on GooglePlay.
