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.
