Stop copying names from a USTA roster into UTR search. MainDraw reads the Players list you have open, looks up National Combined, National Seeding, and UTR for those players, and shows the results in sortable columns—so you can check a tournament draw faster. • Read USTA tournament rosters (singles and doubles) • Look up National Combined, National Seeding, and UTR with your own UTR sign-in • 30-day free Look Up trial for new installs • After trial: $0.99/month or $9.99/year for Look Up Tap a UTR number on a roster or a draw to open that player's profile. In a doubles row, each number opens that player. Tap a National Combined number to see the singles and doubles that count: up to six singles and six doubles, with the lowest counting score marked. Tap a level name to open that tournament. If the USTA access token is expired or about to expire, MainDraw refreshes it in memory so the list can still open. The refreshed token stays in memory. Look Up also shows World Tennis Number beside National Combined. After a lookup, a draw can show Singles UTR or Doubles UTR next to a player you saved. Bookmark a USTA page. The bookmark name starts from the tournament title and the dates on the page. Accounts switches a family player and opens that player's upcoming and completed schedule. Tournament search can save a Sort & Filter setup and open it again. Add a tournament to a personal calendar. Home shows whether UTR and USTA are signed in. Try Demo opens a sample roster with rankings already filled in. No login. The top bar fits narrower and larger iPhones. Switch and Read stay on one line. The small MainDraw title on Home and the UTR Session title are not shown. When a lookup has no UTR session, that notice stays for about 10 seconds and then hides. The UTR Login button is not shown next to it. MainDraw is unofficial and not affiliated with USTA or Universal Tennis.
