Here’s a new twist on the growing market of instant e-Cards–an app that lets you customize an animated message for just about every occasion. Also? It’s free

The YourCards app has a great selection of video e-cards that your children are going to flip over. Each video is about 30 seconds long, plays cute music and sound effects, and can be customized with a personalized message. Once you set up your video you can send it via email, SMS text, or post it on Facebook or Twitter.

Some are very cool (I love the Ladybug Happy Birthday one which gets re-purposed for anniversaries and other events) an s others are a tad cheesy, but there’s enough there that you can definitely find a video card to delight your kids. Or hey, maybe that quirky aunt who just loves getting musical emails.

It also has a built in reminder so that it will let you know that your sister’s birthday is coming up. Perfect for people who are always forgetting that kind of thing, and by people I mean me. -Betsy

The YourCards app is free and is compatible with iPhone, iPod touch, and iPad. Just download it at the iTunes App Store.
