If you're one of those families that just can't seem to keep your stuff straight, Cozi may be your solution. Cozi is a free family organizer that is available across the web and mobile platforms and has just released an app for BlackBerry. All you need to do is sign up for a free account, add your family members and you're good to go. Cozi provides you with a to do list, shopping list and calendar that automatically syncs across all platforms. Your family members are assigned a color so you know who is who, and each can add to the calendar or a list as needed. Cozi is perfect for keeping tabs on all of your family events and works great as a shopping list (lets my wife and I split up in the store so we can divide and conquer). I'm already a huge Cozi fan after using it for only a few short days, but hopefully the app can get a few updates to improve it a bit. As it stands now it's a bit too much of a web inteface and I'd like it to me more of an easy to navigate app. You can check out more in the video above, then head to Cozi.com to get started.
