Grocery IQ (free; iOS and Android) from coupons.com is designed to help you manage your grocery list and save money at the same time. Different categories show when coupons are available, nudging you toward specific brands. You can scan barcodes to add items to a list, find local grocery stores (for me, it only found certain chains, not all of the stores I shop at), and share lists, as well as access them on the web. If you're a coupon maven, you'll find this app practical.
Recipe manager Paprika ($5; iOS and Android) has a built-in browser that helps you find recipes you like on the web, then imports them to your personal recipe list. Paprika will store the recipe so you can make that meal, and you can add all the items you need to a grocery list, then remove the ones you already have.
You can change serving sizes, and Paprika adjusts the quantities you need. Set up meal plans for the week, and each time you go to the grocery store, you'll have a full list of everything you need.
You can't share lists, but if two people log into the same account, Paprika's auto-sync will let them view and edit the same grocery list. You can also email your grocery lists if you want to send them to someone who doesn't have the app. When you're actually cooking, you're better off using a tablet; it's a shame there's no web version to be able to check complicated recipes on a computer.
With all these options, you my finally eschew those paper lists you keep forgetting. Put all your grocery lists on your smartphone and make your shopping a lot easier.
