Features
Everything your month needs. Nothing it doesn't.
No budgeting theory, no spreadsheets. Just your money for this month, clearly laid out.
Bills that repeat themselves
Add rent, subscriptions and utilities as fixed bills once. They appear every month, ready to be paid – even if you skip opening the app for a while.
Never miss a due date Premium
Upcoming bills are front and center, and optional reminders arrive in the morning a few days before each bill is due.
Home screen widget
See your remaining budget at a glance, without opening the app. Available in three sizes – and free for everyone.
Goals & debt payoff Premium
Save toward goals and see when each debt will be paid off. Paying from your budget updates their progress automatically.
Insights & reports Premium
Spot trends with charts and plain-language insights, use your own categories, and export CSV or PDF reports.

FAQ
Good questions
Do I need to link my bank account?
No. MonthBox is manual by design: you add your income and bills yourself. It never asks for banking credentials and has no way to access your accounts.
Is MonthBox really free?
Yes. The budget dashboard, bills, income, the widget and your monthly history are free forever. Premium is optional and adds goals, debt payoff, reminders, insights, custom categories and exports.
Does it sync between my devices?
Not yet – syncing between devices is on the roadmap. Your MonthBox data is included in your iPhone's iCloud or computer backup, so it comes along when you move to a new iPhone.
Where is my data stored?
Only on your device. MonthBox has no servers and no accounts, and it doesn't use analytics or ads.
