About Monoline: AI Expense Tracker
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.
