Kongvene — Your table, organized. Running a mahjong group means more than just showing up to play. There's tracking who owes dues, texting the group to confirm who's in for Thursday, figuring out whose turn it is to host, and scrambling to find a fourth when someone drops. Kongvene handles all of it, so you can focus on the game. Schedule play days, effortlessly. Set a date, and your circle can RSVP right from the app — no more group texts trying to nail down who's actually coming. Track dues without the awkward follow-up. See at a glance who's paid and who hasn't, so you're not the one keeping a mental tally or sending "hey, just a reminder..." texts. Never lose track of hosting duties. Kongvene keeps your rotation in order and shows whose turn is next, so hosting responsibilities stay fair and clear. Fill an empty seat fast. If someone can't make it, broadcast to your circle that you need a fourth — and see who's available, right in the app. Keep your circle connected. Invite members with a simple code, see your roster, and keep everyone on the same page about who's playing when. Whether it's a weekly game with old friends or a rotating group that's still finding its rhythm, Kongvene keeps your table running smoothly — so the only thing you have to think about is your hand.
