While it is not My Digital Studio on a mobile device, it will certainly give you a very small taste of all of the fun and creative things you can do with a full blown MDS download. We want to get our name and our art out there so more people than ever before will know about Stampin' Up!
Download it from iTunes or the App Store. After you create a card, you can send it by text message, email it, or share it on Facebook. I just created this one. It took me less than 5 minutes. Try it out!
