Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Mess Book is a simple, all-in-one app for people who live together, and for anyone who wants to track their own money. Manage your expenses, see how you are spending, and forget old-school ledgers.
Sign in and start right away. Use it on your own to track your expenses and income and to keep a record of money you lend or borrow. Or use it with others: create a group (the creator becomes the admin) or join one with its group ID, or ask the admin to add you. Split bills with flatmates, keep utilities and rent in one place, and settle up with clear reports.
You can switch between your group and your personal expenses any time, even from the home-screen widget, and add an expense in a tap without opening the app.
