The description of Channel 16 Walkie-Talkie

*** Winner of the European Satellite Navigation Competition - Austria, Oct 2014 ***

The basic idea of is to introduce a new way of connecting & communicating with your surroundings during your outdoor activities (sailing, hiking, climbing, mountain biking, paragliding, ...), and in case you have a problem, you can reach other people nearby quickly, and in case someone else has a problem, they can reach you quickly. Works in the city too!

Most messengers out there, like WhatsApp, Voxer, ... are there to communicate between your contacts. is a location-based messenger that allows you to communicate with other people in your area purely based on location. It is the world's first true Walkie-Talkie for smartphones: Audio, text/chat messages, and photos can be broadcasted to other people in your area based on your location.

After months of development with an international team of 3 (#Austria/#Czech/#Japan), an app came to life that mimics what a real Walkie-Talkie / CB / PTT is doing: It broadcasts based on your (ambient) proximity.

Where does the name come from? Channel 16 VHF (very high frequency) is the most important radio frequency on the marine radio band. The "real" Channel 16 on real radio Walkie-Talkies is used to establish a radio connection with others, like with another ship, or with the harbor master. It is also used to broadcast distress calls such as mayday, pan-pan, securite or other urgent safety messages.

Ship-to-ship, or car-to-car?

The app "" at this point can be used for any purpose (not just for sending distress messages), and no radio license is required.
