I don't know about you, but I loved seeing postcards on the fridge growing up from friends and relatives on vacation (especially Disney World). Today, most people just post a photo to Facebook that's Liked a few times and then easily forgotten. Plus, it's not personal. Enter easy-to-use Postcard apps.
Get it Back:
Download an app like Postagram, which lets you send picture postcards for just 99 cents each or $1.99 for addresses in other countries. Your friend will receive a thick, glossy postcard within 2 to 5 business days personalized with a 140-character message. And, yes, you can select a photo from Facebook or your phone's gallery.
Also try Postcards on the Run, which will help you find postal addresses, let you draw your signature with your finger and include a map on your postcard (using your GPS location.) This app will even let you add a Scratch'n Smell scent to your card. Just be prepared to pay more per postcard: $2.49 for U.S. addresses and $2.89 for elsewhere.
