If you are a fan of leaving notes for friends, then you will love the Repudo app. The Repudo app is a new Dutch-designed location-based app that lets you leave text, video, picture and audio messages for friends and strangers.
Using the Repudo app is easy. Simply record your message and set a pickup location. You can send the message to a specific friend or you can leave it open to anyone using the app. The app will notify the sender when their message has been received, and once collected, the message cannot be shared. Repudo sounds like a great way for both friends and marketers to connect like never before. Here's hoping the app hits the U.S. sometime soon. This could very well mean the end of "checking in."
