This is a Scrum tool for voting on story points. When visiting the URL from a desktop, you can see results and control aspects of the session. When visiting from a mobile site, you can vote.
On one computer, set up the room by using the following URL with a unique room name added to the end:
https://murmuring-earth-50512.herokuapp.com/
Example: https://murmuring-earth-50512.herokuapp.com/MyRoom1
From the desktop site you can see the tally of all votes, the vote with the highest representation, and reset all the votes.
On mobile, visit the same URL (shortened URL and QR code provided on the desktop site). You will see a button for each story point. Use the buttons to vote and see your results show up on the desktop site.
