There are a few rules to remember when grocery shopping. No. 1: no fighting. No. 2: don’t forget the list.

Capitan has you covered for that last one. It’s an app for iOS and Android that creates smart grocery lists.

Add your items and Capitan automatically categorizes them by aisle. You can share lists with others so they can add their requests, too.

Capitan will also alert you and those on your shared list if one of you nears the store, so you can remember to pick up items while you’re out.

A little better than pen and paper, eh?
