How it works

1. One of you pays the table. Japanese restaurants often won't split bills — so don't fight it. One person covers it.
2. Log it in 15 seconds. Amount in yen, who paid, who shares. Rates lock at entry, so nobody argues about conversion later.
3. Everyone opens one link. No accounts, no installs. Each person sees their balance in their own currency.
4. Settle once, at the end. "Emma pays Ben ¥9,230" — the minimum number of transfers, not forty IOUs.
