✓About Amppfy
We Built the Number Your Bank App Can’t Show You
Amppfy started with one question: what can we actually spend before payday? The answer is the Safe-to-Spend™ number — your balances minus the bills due before payday, minus planned savings, minus a cushion — with the math shown, for one person or two. Free on iPhone and the web.

WHY WE EXIST
Every money app answered the wrong question
They could tell you where the money went. We wanted to know what was safe to spend, and we wanted both of us to see the same answer.
The founder’s why
The number in the bank app isn’t the answer
Rent hasn’t hit yet. The car payment lands Friday. Amppfy started as the subtraction we were doing in our heads every week — written down once, kept honest in ten minutes a week, and shared so nobody carries it alone.
4lines
The whole calculation, printed under the number. No black box, ever.

10min / week
One check-in keeps it honest. Not a Sunday afternoon, not a spreadsheet.
MTWTFSS
Real screens, real captures — never mock-ups
Built for two
Two logins, one honest number. You choose what’s shared, and nobody hands anyone a spreadsheet.

Same number, both phones
Free on iPhone and the web
Same account, same number, on both. Ads on the web are labeled and never change your number.
HOW WE GOT HERE
From a money site to one honest number
Amppfy began as the guides we wished existed. The app is what the guides kept pointing at.
amppfy.com opens
2025
Plain-English guides and free calculators for people who don’t want a finance degree: budgeting, saving, debt, credit, home, investing, tax.
The web app: Safe-to-Spend™
Summer 2026
One number with the math printed under it, a bill calendar that only counts what’s due before payday, goals that fund themselves first, and a login for your partner.
The iPhone app
September 2026
The same account in your pocket. Sign in with Apple, Google, or email; the number is on both phones and on the web, calculated from the same math.
More for households like yours

The guides, the calculators, and the app keep feeding each other. You’ll hear about what’s new first if you use the app.

The math is always shown. No black box in the app, no hidden angle in a guide, and reader feedback gets a straight answer.
Practical and Calm
Advice you can act on this week, in a tone that never scolds. Heads-ups, not alarms; a next step, never a grade.
Trust You Can Check
Research-backed guides, labeled ads, disclosed partner offers, and an app that runs on the balances you choose to enter.
THE OTHER HALF OF AMPPFY

Budgeting, saving, debt, credit, home, investing, and tax, written for beginners and checked before they publish.
