About Mona: Budget & Expense Tracker
Mona answers the one question a money app should: how much can I actually spend? Not your balance. Not what is left in the account. What is genuinely yours to spend today — once this month's budget and the bills already on their way out have been counted. Free — every feature, no subscription, no ads. SAFE TO SPEND One number, at the top of the screen. Your budget, minus what you have spent, minus the rent and subscriptions Mona has found in your own history and set aside before showing you the figure. No app should tell you the rent is available to spend. AN ANSWER FOR TODAY Mona divides what is left across the days remaining, so every day has a number. Stay near it and you land inside your budget. SEE WHERE THE MONTH LANDS One bar carries two things at once: how much you have spent, and how much of the month has gone. Fill behind the marker means you are pacing well. Mona projects where you will finish while there is still time to change it.

What’s new
Version 2.3.1 · Updated October 14, 2026
Mona now fits iPhone Duo. • Open it and Mona uses both pages: what's safe to spend and how the month is going on the left, your budgets and today's transactions on the right. Activity, Budgets and Insights split the same way • The bar for adding an expense sits on the right-hand page, clear of the fold • Closed, the bars stand along the side as iPhone Duo intends, and everything fits its narrower screen Setup and the keypad fit smaller screens. • Entering your starting balance no longer pushes the back button and Continue off the screen on smaller iPhones • The keypad for a new expense tightens up when space is short, so the button that saves it stays in view • The welcome screen is no longer nudged to the left Budgets, the keypad and search, put right. • Today and Budgets now agree on how many days are left and what you can spend each day, including on a budget's last day • Over budget, Mona says so and shows by how much, instead of putting a minus sign on what's safe to spend • Typing over an amount you're editing replaces it, rather than adding digits to the end • In currencies counted in thousands, like the đồng and the rupiah, the keypad has a 000 key and its shortcuts add thousands • Search finds words typed without accents, and amounts typed the way Mona shows them • A new icon, drawn to stay clear on tinted and clear Home Screens Thank you for using Mona. Know what you can spend.
