I managed finances in spreadsheets for years. Every budgeting app wanted bank linking and monthly fees. I wanted to see what's coming, not track what already happened. Nothing did that. So I built it.
Powerful — but a lot of work. Once formulas and cell references stack up, they get fragile.
No thousands of cells. No formulas to chase. Just your numbers — and the outcome updates live with every change.
I used it to see that my wife and I could actually retire someday — a worry I always put off facing. The stress of not knowing lifted, and it gave me the clarity to plan in my reality.
No bank linking. No cloud storage. Your financial plan lives on your device and nowhere else. That's not a limitation — it's the point.
The people who need financial planning tools the most are the same people exhausted by recurring charges. One payment. Yours forever.
Seeing your numbers clearly — really seeing them — replaces guessing with a clearer picture. That moment frees you to think about what comes next.
Other apps tell you where your money went. Kevin's Cash projects where your numbers could be heading based on what you enter.
You enter your numbers. You see what they mean over time. You make your own decisions. Kevin's Cash is a calculator — it shows you the picture your numbers paint.
I use it every day. I built it for myself first. Now it's yours too.
