Kalendo · Budget calendar

A budget app that shows what will be left

Rent, salary, subscriptions: enter them once. Kalendo spreads them across the calendar and works out your balance for every single day — so “can I afford this on the 20th?” is answered on screen.

Kalendo — Budget calendar with daily balance

Features

A calendar that does the math ahead of you

Your budget on a calendar

A month grid with income and expense marks on every day. Today's balance and the month-end forecast side by side.

Recurring items, entered once

Daily, weekly, monthly and yearly rules. Salary, rent and subscriptions come back on their own, with a reminder before they're due.

“What if?” before you buy

Try a purchase or an instalment plan and see each month's end balance — and the month you'd go below zero.

Budgets, goals and debt

Monthly limits per category, savings goals with a forecast date, money lent and borrowed, separate cash, bank and card accounts.

Honest numbers

“Fix balance” books the gap as unlogged spending. With too little data it says so instead of inventing a confident number.

Your data stays yours

No account, no server. Everything lives on your phone — export a JSON backup, import CSV, lock with PIN or biometrics.

How it works

Three steps

Add what repeats

Enter salary, rent, bills and subscriptions once.

Read the calendar

Every day shows the balance you'll have, not just what you spent.

Ask “What if?”

Test a purchase or instalment plan before you commit.
