✩ Go to your beach, type a message, put it into your drift bottle and throw it into the sea! ✩
I've been trying this app for some time now and I must say it is a lot of fun. I first tried out the free version and later switched tot the paid version (0,99$) since it allows you to send pictures. And I've already received several pictures from all over the world.
I've had conversations with random people from all over the world. The app also allowes you the track your message on a map. All very nice!
