If an event isn't being organized on Facebook, it's probably being done through Eventbrite. This service makes it easy to manage invites, RSVPs, and even ticket purchasing. Attendees get handy reminders about the events they planned to attend, organizers can see guest lists. We particularly like that Eventbrite can generate QR codes, making event check-in a breeze.

You could try an app that’s designed to improve the app discovery process and aid you in finding the content you want, but that still ultimately plugs into the Play Store to download and install apps and games.
