PAYCHECK BUDGET, FOLDABLE EDITION
Close your phone and see one number: what's left to spend until payday. Open it and see the whole plan: every paycheck, every bill, every savings goal.

★ WHAT IT DOES
• Budgets one paycheck at a time. Each bill is paid from the last paycheck before it's due, so you never sort anything.
• Spots a paycheck that comes up short, weeks ahead, and suggests a one-tap fix: pay a bill early from a roomier check.
• Logs spending in two taps. Left to spend updates on the spot.
• Savings come out first: emergency fund, Christmas, car repairs, any goal, with the date you'll reach it.
• Weekly, every two weeks, twice a month or monthly pay. Weekend paydays can move to Friday.
• Backup and restore in one tap. Export spending to CSV.

★ MADE FOR TWO SCREENS
On iPhone Duo, the cover screen is the quick glance and the inner screen shows two pages side by side: your paycheck and the plan. Fold or unfold any time; nothing reloads. On any other phone, tablet or computer you get the same app, sized to your screen.

★ COMPATIBILITY
Runs in Safari on iPhone Duo (iOS 27.1), tested in Apple's iPhone Duo simulator. Also runs on other iPhone models, iPad, Android phones (Chrome) and computer browsers (Chrome, Edge, Safari).

★ HOW YOU GET IT (about a minute)
1. Download the zip and open START-HERE.pdf.
2. Tap your private install link (or scan the QR code). It opens in Safari.
3. Tap the Page Menu button (•••), then Share. If your toolbar shows a Share button, tap that instead.
4. Tap View More, then Add to Home Screen. Leave Open as Web App on, then tap Add.
5. Open it from your Home Screen from now on. It works offline.
This is a web app that installs from Safari. It is not an App Store app.

★ WHAT'S INCLUDED
• The Paycheck Budget, Foldable Edition web app: your private install link and a QR code are in START-HERE.pdf
• The Paycheck Budget Spreadsheet for Excel and Google Sheets, with a Couples Edition and three bonus themes
• START-HERE.pdf: install, set up and your first paycheck in about ten minutes
• Free updates: the app updates itself when we improve it

★ PRIVATE BY DESIGN
The numbers you enter are saved only on your device, in the web app's storage. We never receive them. There's no account and no cloud sync. Deleting the web app or clearing Safari website data erases your entries, so save a backup file now and then.

★ GOOD TO KNOW
• Digital download. Nothing is shipped.
• For personal use. Please don't share your install link or resell the files.
• For personal budgeting and education only. Not financial, investment, tax or legal advice.
• The kitchen-table photo is an AI-generated illustration; the app screen in it is a real screenshot of this product.
• Designed by NicheToolkits with the help of AI tools.
