It's basically an app for saying "I'm ready" or "Let's do x...".
Background is that my friend group plays video games, grabs beer or whatever - and a lot of the communication revolves around logistics. This app lowered the threshold for initiating. We create a group per activity, and "going green" means you're ready. The other group members get a push notification "Paul is greenlit!" and the title of the group is "Play Dota 2" or "Beer at local pub". Super simple concept, but it actually works.
TLDR; I made an app that let's you press a button instead of writing the typical "Does anyone want to join x activity?"
Currently iPhone only.
