跟球隊管理員要 6 碼邀請碼，登入後輸入，填暱稱、性別和自評級數即可。選級數時每一級都有文字說明，照實填就好，之後會依戰績自動修正。
按「建立球隊」就是第一位管理員。到「設定」把邀請碼貼給球友；開新球賽後球友會自己報名，當天在球賽頁報到、按「開始球賽」、「排下一輪」。App 內「設定 › 使用說明」有完整的主辦者流程。
每個人有一個隱藏實力值，顯示級數是四捨五入後的整數。同級對手對打，贏一場約 +0.1、輸一場約 −0.1，大約 10 場勝利跨一整級。前 10 場（新手期）變化加倍，讓自評偏差快點修正。贏比自己強的對手加得多，輸給弱的扣得多。
任何會員都可以「幫人新增」代填會員。代填會員不用報名，當天由主辦者在報到畫面勾選，打完由同場球友或管理員按勝負。配對結果也可以用「分享」做成圖片貼到 LINE 群。
「設定 › 刪除帳號」。刪除前會請你再用 Apple 驗證一次，之後 Apple 登入授權會被撤銷、個人資料清除；比賽紀錄保留但顯示為「已離隊會員」。若你是球隊唯一管理員，請先指定另一位管理員。

Ask your club admin for the 6-character invite code, sign in, enter it, then fill in your nickname, gender and self-rated level. Each level has a description; answer honestly and results will correct it over time.
Tap "Create club" to become its first admin. Share the invite code from Settings; create a session and members sign themselves up. On the day, check people in, tap "Start session", then "Next round". The full organizer guide is under Settings › Help in the App.
Everyone has a hidden rating; the displayed level is the rounded value. Against an equal opponent a win is about +0.1 and a loss about −0.1, so roughly 10 wins move you up a level. Your first 10 games count double so a mis-estimated starting level corrects quickly. Beating stronger opponents gains more; losing to weaker ones costs more.
Any member can add a "proxy member" for them. Proxy members don't sign up; the organizer checks them in on the day and anyone on court or an admin reports their results. Pairings can also be shared as an image to your chat group.
Settings › Delete account. You will be asked to verify with Apple once more; the App then revokes your Sign in with Apple authorization and erases your personal data. Match records remain, shown as "former member". If you are the club's only admin, appoint another admin first.
