The result is a forecast that reflects your life, not a statistical average.

Budgeting apps track what you've already spent. Know Your Money looks forward — it forecasts your future balances so you can see what's coming before it arrives. Think of it less like a ledger and more like a financial GPS.
No — and that's intentional. Know Your Money doesn't offer investment advice, tax guidance, or wealth management services. It's a personal forecasting tool: you enter your numbers, and it shows you where those numbers lead. Simple, honest, and entirely in your control.
Projections are as accurate as the data you enter. The app uses your income, recurring expenses, and one-time transactions to calculate rolling balances. For retirement and investment projections, you set your own return assumptions — the app never substitutes generic rules of thumb like the "4% rule" for your actual situation.
Yes. You can set custom return rates for investments, adjust withdrawal amounts, set opening balances per account, and override recurring transactions for specific months. Everything is based on what you enter — not industry defaults.
Completely. All data is stored locally on your iPhone — it is never uploaded to any server, synced to the cloud, or shared with anyone. We have no access to your financial information. No account is required to use the app.
Not at all. If you know your paycheck amount, your monthly bills, and your bank balance, you have everything you need to get started.
You set the thresholds. The app alerts you when projected balances fall below a custom floor — like $1,000 or $0. For retirement, it shows the projected date your savings account would reach zero at your current withdrawal rate — calculated from your data, not a formula.
