MonoBudget: Fixed Costs

Finally know what's actually left at the end of the month.

MonoBudget is a household budget planner built around your fixed costs. Enter your income and your recurring bills, and within minutes you'll see how much money is genuinely free to spend each month. No bank connection, no account, no ads.

SET UP IN 5 MINUTES

Add your salary, add your fixed costs, done. No lengthy onboarding, no category spreadsheets to fill in first.

→ Enter your income: salary, side job, benefits → Add your fixed costs: rent, insurance, utilities, subscriptions → MonoBudget immediately shows you what's left

Once a cost is set up, MonoBudget keeps creating its monthly entries for you. There's nothing to maintain.

NOT AN EXPENSE TRACKER

You don't log every coffee here. This is about your fixed, predictable costs — so you know what's genuinely available to spend, and where to start if you want to save.

YOUR DATA STAYS WITH YOU

No account, no sign-up, no MonoBudget server, no tracking. Your financial data lives locally on your iPhone.

Back up only if you want to. Encryption happens on the device with a passphrase only you know, and you decide whether a backup stays on your iPhone or goes to your iCloud Drive. You can also export plain JSON at any time and take your data with you.
