If you are a LifeTime member, you probably have the LifeTime App setup already. You use it to show your QR code or to tap in to get access to the clubs. You use the LifeTime app to sign up for open plays, reserve courts, and more importantly, to cancel your reservations if you do not need them anymore.
TeamReach
The TeamReach app is a group chat app that we use to chat with each other in this LifeTime Pickleball community. The Pickleball team uses it to communicate news and updates to programs. There are different “Groups” on TeamReach beyond the main one (insert name). Those smaller groups are often event specific (like League).
DUPR
DUPR is a Pickleball rating system that helps the Pickleball community settle on a rating standard that is data based. See How do I get a DUPR Rating?
