Noyumi

Keep everyday spending clear with Noyumi, whether you are recording your own expenses or sharing costs with family and friends. A private ledger, plus shared ledgers Keep your personal entries separate. Create multiple shared ledgers for home, trips, or plans together, each with its own members, invitations, and default currency. Invite people with a code Administrators create invitation codes. A new member enters or explicitly pastes a code, reviews the invitation, then confirms to join. Each code is valid for 7 days, can be used by one person, and can be revoked. Share the invitation as text or save an invitation card. Easier entries and clearer history Record an amount, currency, category, date, payer, and note. Use Record again to reuse an expense, or save it as a template on this device. Keep an unfinished entry as a draft and continue editing later. Undo a deletion from its action notice. Review refunds and field-by-field edit history, and search the current ledger across months by keyword, currency, category, payer, or date range. Templates stay on this device and are removed when you sign out. Shared templates require a connection and continued access to their ledger. Original totals and reference conversion Use 12 currencies: CNY, JPY, USD, EUR, GBP, HKD, TWD, KRW, AUD, CAD, DKK, and SEK. The monthly overview keeps each currency's original net total visible. A menu switches the category breakdown and chart between individual currencies or reference amounts in the ledger's default currency. Conversion uses public reference rates for the expense date; refunds use the original expense's rate. Inspect original amounts, converted amounts, and rate dates. Missing or provisional rates are clearly marked. These amounts are for statistical reference and may differ from actual bank settlement. Conversion does not change entries, currencies, or expense shares. Changing a default currency does not rewrite past records. Equal or custom expense shares Choose who participates in a shared expense, then split the amount equally or enter each person's share. Refunds adjust net shares in their original proportions. Payer and participant statistics remain in original currencies; reference conversion applies to spending categories. The app records and summarizes costs; it does not settle debts or manage reimbursement approvals. Export a month as CSV Export expenses and refunds from the selected ledger and month to keep a copy or continue working in a spreadsheet. Four interface languages Choose Simplified Chinese, Traditional Chinese, English, or Japanese. The app follows your device language by default. Navigate to expense details and ledger management as pages, and use forms to create or edit records. Sign in with Apple is required. Private entries are protected by account permissions and are not visible in the app to other members or shared-ledger administrators. Records are stored on a server; this version does not use end-to-end encryption. Read the privacy policy or delete your account in Settings → Account & privacy.
