A simple slack app that you can use to add a /elo command for your Slack team. Once added, /elo allows your team members to log games against each other for different types of games (ex. pingpong, foosball, etc) and have this app automatically keep track of everyone's Elo rating for each of the games. Provides the functionality to view your Elo rating or even see the leaderboards.
