One Clear Number for What’s Safe to Spend Before Payday
The number in your bank app isn’t the answer — rent hasn’t hit yet. Amppfy turns your accounts, bills, and goals into what you actually want to know: one clear number for what’s safe to spend before payday. It updates the moment anything changes, and the math is always shown. Free on iPhone, with the same account on the web.
Amppfy is a free safe to spend app for iPhone and the web: enter your balances, bills, and payday, and it shows one number for what’s safe to spend before your next payday — with the math printed under it.

HOW IT WORKS
From your balances to your number in ten minutes
No categories, no transactions. Just the four numbers that decide what’s safe to spend.
Type in your balances
Checking, savings, cash — about 30 seconds each. That’s all the app needs to start.
Add your bills and payday
The common ones are pre-listed. Only what’s due before your next paycheck counts against your number.
See your number
Safe to Spend, with the four-line math printed under it — on your iPhone, your partner’s phone, and the web.
THE PROMISE
Everything the number already knows
Real screens from the app. Every stat here is a fact about the product, not a claim about you.
One clear number, with the math under it
Available cash, minus bills before payday, minus planned savings, minus your cushion. Every line shown, every time.

The whole calculation, printed under your number. No black box.
One check-in keeps it honest. Miss a week and nothing breaks.

Type balances in yourself — quick, and nothing to maintain between check-ins.

Goals fund themselves first
Like bills. Spending comes from what’s truly left — and you can pause a goal in a tight month.
Heads-ups, not alarms
Amber for things that need a look, green for the good number. Nothing red for ordinary life.

BILLS & PAYDAYS
Know Your Bills Are Covered Before They’re Due
Every upcoming bill and every paycheck, on one calendar. Amppfy counts what’s due before your next payday, so you can see what’s covered and what’s safe to spend — before anything tips you into the red.
IF YOU SHARE MONEY
Two Logins, One Honest Number
Sharing money with someone? Invite them by email. They get their own login, they see what you choose to share, and you both see the same number.
If you set things up
You get the full picture in one place — and you stop carrying it all in your head.
If you were invited
You see the same number and the same math — ten minutes a week, and nobody hands you a spreadsheet.

ON BOTH SCREENS
THE WEEKLY CHECK-IN
Ten Minutes a Week Keeps Your Number Honest
Once a week, confirm your balances and glance at upcoming bills. That’s the whole job — about ten minutes.
Miss a week? Nothing breaks. Pick it back up when you’re ready.
THE IPHONE APP
Your Number, in Your Pocket
Get Amppfy on your iPhone and the answer is always with you — the same number on your partner’s phone and on the web, calculated from the same math.
In line at the grocery store, at the kitchen table, on payday morning: open it, glance, done.

Bank balances & budget apps
Useful — but they answer a different question.
- A balance isn’t spendability — rent hasn’t hit yet
- Rarely shows the math
- Tells you after the fact, or at month end
- Mostly one login
- Constant categorizing, or nothing at all
- Usually needs your bank login — and the sync can break
- $8–15/mo for the big names
