Postcardly Postcards is a neat service that allows you to create a postcard using your own photos, then have it sent via snail mail to a recipient for a reasonable price. The process is almost perfect and I really like the idea, but some small tweaks would make the app even better.
Creating a postcard is dead simple. You start by snapping a photo or choosing one from your iPhone's photo library. Then, you can move and scale the photo to make it fit on the postcard the way you want (more on this later). When you're satisfied with the positioning, you can move on to the next screen to type out your message (with a maximum of 500 characters -- about 100 words) and add an address. Postcardly Postcards lets you either type in the address yourself or choose a person from your iPhone's contact list and autofill the info (if you have the address entered for that person).
When you're finished putting it together, you're almost ready to send your postcard. Postcardly Postcards requires that you enter your name and credit card information on your first postcard, with an introductory price of $1.99 for five postcards. So what you're getting for your $1.99 (initially) are five physical postcards you can send to your recipients, along with personalized photos and messages. When you use up your first five postcards, you can either sign up for a subscription ($4.99/month for five cards a month, $9.99/month for 15 cards a month) or just pay a one-time $19.99 for 20 postcards. While it may seem a little pricey, I think the convenience of sending postcards from my iPhone is really cool, and the gesture to friends or family members when they receive them in the mail is worth the money.
