Radar Chat allows users to leave digital messages that are attached to physical world locations. Most messages can only be seen if you're physically close to them which can be used to make scavenger hunts. My first customers non-profits in the STEM space who are using Radar Chat to tag the businesses they partner with (Planetariums, Science Museums, etc). When students visit these places they can then check into them (if they're close enough) and get entered to win a prize. Here's an example of a STEM customer channel: https://app.radar.chat/#/channel/glbra-stem-pipeline https://app.radar.chat/#/channel/glbra-stem-pipeline Paying customers unlock additional features like permanent messages, always-visible messages, and messages that can be checked in to. Non-paying users are able to leave messages that have a maximum radius and an expiration time. I do server programming by trade so any feedback on the UX would be greatly appreciated!
