Pretty simple one to track my own club badminton scores and history https://www.elosmash.com/ Other clubs were interested so I made it multi users. Idk it works well for my club

Hi, very cool. We are actually building a similar app (https://play.google.com/store/apps/details?id=com.arenaxgame... / https://arenaxgame.com). Our app is still in the early stages, we have yet to onboard venues. We are planning to have robust ranking system, exp / leveling system; and also allow users to book slots in venues to play / share games and discover other players,.. Let me know if you are interested in collaboration.
