Since we're on the road so much, we're always on the lookout for a good postcard app. And an old favorite was just released for Andronid. Postcard on the Run has a great UI, with easy instructions and options to use pictures from the camera, your gallery or even Facebook. Pick the pic, and Postcard on the Run mails it anywhere in the world.
But what if you don't know the physical address? (That's a common problem in a lot of address books these days.) Postard on the Run has its "Postal Gopher." Just give it the e-mail address or cell phone number of the person you're trying to send to, and it'll contact them, then update your address book and send. Other options include cropping the photo, leaving a message, adding a real signature (as in sign with your finger) and even a GPS map of your location you're sending from. It's pretty slick.
Prices vary from 99 cents to $1.69 per postcard sent (add 20 cents for international), and you can pay by credit card or PayPal. (We'd love to see in-app billing added so we don't have to enter our credit card -- again.)
We'll be giving this one a go this weekend from the Big Android BBQ, no doubt. Hit up the download links after the break.
