Tennis, without the group-chat chaos
Set the times you're open, post a game, and let your friends fill the spots. Booked the court? Say which one.
Drop your open times on the calendar: Saturday morning, Tuesday after class.
Singles, doubles or mixed. Booked a court already? Mark it and pick the number.
Your friends see the game and hop in. Spots stay balanced, so nobody shows up to a lopsided court.
