Pika

Pika is a mobile app that let's you connect friends with picture, yes, that's right. You take a picture of where you're at and @yourfriend if you're with them. Your other friends can take "a pika", and see where you're at on a clean map, of course, with the friends you trust. In the future, you can share with your kids, I guess, then go to those places again and "re-download" those memories.
