Plan before you spend
Add a larger future expense and see how it may change the months that follow.
A REAL VIEW OF THE APP
Make the months ahead visible.
These screens use sample data to show the decisions Balance Window is built for—not every coffee you buy.
HOW IT WORKS
A useful forecast starts with what you already know.
No bank connection, import feed, or daily bookkeeping routine required.
Start with your balances
Add up to two money accounts and enter the balances you have now.
Add paychecks, bills, and plans
Enter recurring income and expenses, plus one-time purchases or payments on future dates.
Explore the months ahead
Pan, pinch, and open any date to see how your planned money changes shape the forecast.
A DIFFERENT JOB
Planning ahead, not tracking every purchase.
Traditional expense trackers explain where your money went. Balance Window helps you explore where your balance may be going. Record the important changes you can already see—paychecks, rent, insurance, card payments, and larger plans—without logging every coffee.
“Will my balance stay above zero until my next paycheck?”
Look back
Detailed categories and history can tell you what happened to your money.
Look ahead
Balance Window shows how known changes may shape the balance that follows.
PRIVATE BY DEFAULT
Local first. Cloud only when you choose.

Portable JSON backup
Import or export a local JSON backup. Web and iOS can work independently with the same data format.
QUESTIONS
A clear starting point.
Is Balance Window a budgeting or expense-tracking app?
Not in the traditional sense. Balance Window focuses on future balance and cash-flow timing. You can record important planned income and expenses without tracking every purchase.
Do I need to connect a bank?
No. Balance Window is designed for manual, local-first planning and does not require a bank connection.
Do I need an account?
No. The core app works locally without signing in. Sign in with Apple is optional and enables cloud backup and sync.
What should I add to the forecast?
Start with current balances, recurring paychecks, rent or mortgage, insurance, card payments, utilities, subscriptions, and any larger expense you already plan to make.
Is the forecast a real-time bank balance?
No. It is a planning projection based on the balances and money changes you enter. Actual results may differ.
How many accounts does version 1.0 support?
Version 1.0 supports up to two money accounts. Balance Window is a planning tool, not a bank, payment service, accounting system, or source of financial or investment advice.
