About Bill Organizer

Bill Organizer is made by Dixon App Studio (DixonAppStudio LLC), an independent developer of small, focused apps. It started as an Android app, came to iPhone and iPad, and this website is its web version.

What we believe about bill apps

No bank login. You shouldn't need to hand over banking credentials to remember when the electric bill is due.
No account. Your bills stay on your device. We can't see them, lose them or leak them.
Free stays free. The app is free with ads. Optional Bill Organizer Pro (a 7-day free trial, then $2.99 a month or $14.99 a year, or $24.99 once) removes ads and adds extras; nothing that was free moved behind it. The website and online tracker are free, with no account.

How the calculators are built

The 71 calculators use the same formulas as the app (all 57 calculators are in it): standard amortisation for loans, month-by-month simulation for debt payoff, and monthly compounding for savings. Those formulas are covered by automated tests, including textbook cases like a $200,000, 30-year loan at 6% costing $1,199.10 a month. Every calculator page shows its formula and a worked example generated from the calculator itself.

Calculators give estimates for planning. They aren't financial, tax or legal advice, and your lender's or landlord's terms always take precedence.
