About this app

The developer's US App Store description, in full.

Six Functions of a $1 is a fast, focused calculator for the six essential compound interest factors used in real estate, finance, and investment analysis: future value, present value, sinking fund, present value of an annuity, future value of an annuity, and capital recovery. Enter an interest rate and a number of periods, choose your compounding frequency, and get all six results instantly — no formulas to remember, no spreadsheets to build. Built for privacy from the ground up: every calculation happens directly on your device. There are no accounts to create, no data sent to a server, and no internet connection required. Your numbers stay yours. FEATURES Six Core Calculations Future value, present value, sinking fund factor, present value of an annuity, future value of an annuity, and capital recovery — computed simultaneously from a single rate and period input. Calculation History Every calculation you save is stored locally so you can revisit, duplicate, or reload it into the calculator later. 100% Offline No network connection is ever required. The app works the same on a plane, underground, or with airplane mode on. Private by Design No accounts, no sign-in, no analytics, no third-party tracking. Nothing leaves your device. Clean, Modern Interface A distraction-free dark interface built natively in SwiftUI, designed for quick reading of precise numbers.
