Friend finder enables you to see where your friends are in real time.
You can become friend with anybody that wears the smart wristband: Just keep your and your friends wristbands close together and simultaneously press the button on the wristbands and you are friends.
The Friend finder app does only store the nickname you select and your wristband id, no email or phone id.
Friend Finder is developed with the MONICA research project which is co-funded by the European Union’s Horizon 2020 Framework Programme for Research and Innovation under Grant Agreement No 732350
