Debt Payoff Planner, Foldable Edition
Close your phone and see your debt-free date and your next payment. Open it and see the whole plan, and what an extra $100 or $200 a month would do.
Laid out for both screens
One number when it is closed
Close the phone and the cover screen answers one question at a glance: what is left to spend until payday, or your debt-free date and your next payment.
Two pages when it opens
Open it and the inner screen shows two pages side by side: your paycheck next to the plan, or your debts next to the payoff plan. Fold or unfold any time; nothing reloads.
Private, offline, yours to keep
No account, no bank login and no subscription. Your numbers stay on your device, and the matching spreadsheet for Excel and Google Sheets comes with every app.

Questions
Do I need an iPhone Duo to use these apps?
No. A big foldable inner screen gets the two-page layout, and any other iPhone, Android phone, iPad or computer gets the same app, sized to its screen. The Excel and Google Sheets spreadsheet is included too.
Are these App Store apps?
No. They are web apps that install from Safari with Add to Home Screen, then open from your Home Screen like any other app. There is nothing to download from an app store.
Have they been tested on iPhone Duo?
They run in Safari on iPhone Duo (iOS 27.1) and were tested in Apple’s iPhone Duo simulator. They also run on other iPhone models, iPad, Android phones in Chrome and computer browsers (Chrome, Edge and Safari).
Do they connect to my bank?
No. You type in your own numbers. There is no account, no bank login and no cloud sync, and your entries are saved only on your device.
Do they work offline?
Yes. After the first open they work offline, even in airplane mode.
What do I get when I buy one?
One ZIP: a START-HERE guide with your private install link and a QR code, the matching spreadsheet for Excel and Google Sheets, and the link to the free video walkthrough. One-time purchase, no subscription.
