## What is Monoline?

One line is all it takes.

Write "lunch burrito 12" the way you'd text a friend, and Monoline fills in the amount, category, and place. No forms, no endless setup.

• One-line entry — write naturally, it gets sorted
• Several at once — "coffee 4.5, subway 2.75" becomes two entries
• Voice — tap the mic and say it; fix the transcript right there
• Receipts — snap one or several photos, items and totals are read for you
• Shared ledgers — one invite link and your partner or family logs into the same ledger; see who added what
• Day — one photo and one line about today, with an AI look-back at the end of the month
• Ask AI — ask anything about your spending, answered from your own entries
• Reports — monthly and yearly reports of tables and charts, built from your own entries
• Foreign currency — write "¥1,200" and it converts at that day's rate, original kept in the memo
• Separate ledgers — travel, emergency fund, each with its own currency; period ledgers for trips and events
• Clean stats — spending by category and by month at a glance
• iCloud Drive backup — restore after a new phone or a reinstall
• No account needed — your entries live on your phone; sign in only when you share a ledger

Start right away. No sign-up.

Monoline Plus (optional subscription): unlimited ledgers and Apple Pay auto-record — payments logged through a Shortcut even when the app is closed. The free app keeps everything above, including AI chat, reports and shared ledgers, with 2 ledgers and a 10-entry auto-record trial. Monthly or yearly, cancel anytime in Settings.

### 5/5 — 한 줄이라 꾸준히 쓰게 되는 가계부

*2026-06-05*

가계부 앱 여러 개 써봤는데 대부분 입력이 귀찮아서 포기했었습니다. 이 앱은 그냥 "점심 김밥 5천원"처럼 한 줄만 적으면 되니까 부담이 없네요. 복잡한 설정 없이 빠르게 기록할 수 있어서 오히려 더 자주 쓰게 됩니다. 꾸준히 가계부 쓰고 싶은 분들에게 추천합니다.
