Seedline: Bracket Maker

Seedline makes brackets for real tournaments: office ping-pong, darts night, pickleball clubs, esports, cornhole, chess or game night. Add your players, pick a format and the bracket is ready. Tap a match to record the winner and everyone moves on automatically. Formats • Single elimination with proper seeding: seeds 1 and 2 can only meet in the final, and top seeds get byes when the numbers don't divide evenly. • Double elimination with a full losers bracket. Players drop into it on the opposite side so early opponents don't meet again, then the grand final, with a bracket reset if the losers-bracket champion wins. • Round robin: every player meets every other, with a full schedule and a live table (points, then head-to-head, then score difference). Running it • "Up next" always shows the next match that can be played. • Optional scores. Enter both and the winner is picked for you. • Made a mistake? Change any result. Seedline tells you exactly which later matches it affects. • Pinch to zoom on big brackets, up to 64 players. • Share the whole bracket or table as a poster image. • Ask Siri "What's next in Seedline?" to hear the next match. Free, with no account, no ads and no tracking. Your tournaments stay on your iPhone.
