TVM, cash flows, bonds, amortization, statistics, and a full calculator emulator — built for finance professionals, CFA candidates, and students. No accounts. No ads. Everything stays on your device.
Each one mirrors the logic finance courses actually teach — not a simplified consumer version of it.
N, I/Y, PV, PMT, FV — solve for any one, END or BGN mode, with true bisection for I/Y.
Full cash-flow worksheet with a multi-IRR warning when a project's cash flows change sign more than once.
Price ↔ yield, current yield, Macaulay and modified duration, and convexity in one worksheet.
Full payment schedule with a principal/interest split you can export to PDF or CSV.
Straight-line, double-declining balance, and sum-of-years'-digits schedules, side by side.
Mean, median, standard deviation, variance, plus covariance, correlation, and beta.
The full keypad layout — 2nd functions, STO/RCL memories, a scrolling keystroke tape, haptics.
ROI, CAGR, break-even, contribution margin, cap rate, DSCR, markup vs. margin, and more — two taps from launch.
Every formula links straight to the worksheet that solves it, and the ones marked for deeper study open a full learn page — steps, keystrokes, worked examples, common mistakes.
Navy surfaces, soft gold accents, and tabular monospaced digits on every number — the same visual density as the tools this is meant to replace. Every key press on the emulator gets real haptic feedback, because that tactility is half of what a calculator is for.
