如何使用「AA 记账分账（多人聚餐旅行结算）」？How do I use the Group Expense Splitter (Who Owes Whom)?
先添加所有成员，然后每一笔消费填写内容、金额，选择谁付的钱和谁参与分摊（默认全部人），点“记一笔”。下方会实时显示结算结果和“谁该给谁转多少钱”，最后点“复制结算文字”发到群里。数据会自动保存在本机。Add everyone first, then for each expense enter what and how much, who paid and who shares it (default everyone) and press Add. Settlement and who-pays-whom update live; press Copy summary to post it in the group chat. Data autosaves on this device.
结算方案是怎么算出来的？How is the settlement calculated?
先算出每个人“已付 − 应摊”的差额，差额为正的人应该收钱，为负的人应该付钱，再把欠款最多的人和应收最多的人依次配对，用尽量少的转账次数结清所有账。Each person’s balance is paid minus share; positive balances receive and negative ones pay. The largest debtor is matched with the largest creditor repeatedly, settling everything in as few transfers as possible.
有人只参与了部分消费怎么办？What if someone joined only some expenses?
记账时在“谁参与分摊”里取消勾选没参与的人即可，这笔钱只在勾选的人之间平分。如果有人带家属，勾选“按份数分”并把他的份数改成 2 或 3。Untick people who were not part of that expense — it is split only among those ticked. For someone with family, tick Split by shares and set their share to 2 or 3.
分不尽的零头怎么处理？How are leftover cents handled?
金额按“分”精确计算，除不尽的 1 分钱会依次分配给参与人，保证所有人应摊之和正好等于总金额。Amounts are computed in cents; any leftover cent is assigned in turn so the shares add up exactly to the total.
