## What is FinanceRPN?

FinanceRPN is a professional-grade RPN (Reverse Polish Notation) financial calculator built for finance students, exam candidates, and
working professionals who demand precision and reliability.

WHY FINANCERPN

Built after analyzing hundreds of real user complaints about existing financial calculator apps — crashes, calculation errors, missing iPad
support, and confusing subscription pricing — FinanceRPN was designed from the ground up to solve those exact problems.

CORE FEATURES

- Time Value of Money (TVM) — solve for N, I%YR, PV, PMT, and FV with full support for both BEGIN and END payment timing
- Cash Flow Analysis — NPV and IRR calculations for uneven cash flows
- Date Calculations — accurate day-count calculations with full support for dates beyond 2049, using both Actual and 30/360 conventions
- Memory Registers — 10 storage registers (STO/RCL) for complex multi-step calculations
- Calculation Tape — a full history of your calculation steps, grouped by session, so you never lose track of your work
- Built-in Manual — step-by-step tutorials with real worked examples for every major function, right inside the app
- Native iPad Support — a genuinely redesigned layout for iPad landscape and Split View, not just a stretched phone screen

DESIGNED FOR PRECISION

Every calculation in FinanceRPN's engine has been unit-tested, including edge cases that other calculator apps get wrong — such as
date calculations spanning the year 2049 and beyond, which is essential for fixed-income and bond maturity calculations.

WORKS COMPLETELY OFFLINE

FinanceRPN requires no internet connection and no account. All your data stays on your device — nothing is ever uploaded to any server.

ONE-TIME PURCHASE. NO SUBSCRIPTIONS.

Pay once, own it forever. No monthly fees, no hidden paywalls, no "free trial" that stops working after a week. Just a complete, professional financial calculator.

WHO IT'S FOR

- CFA, FRM, CPA, and actuarial exam candidates
- MBA and finance students
- Financial analysts and professionals who grew up on RPN calculators and want that same speed and precision on their iPhone or iPad
