my12c

The financial calculator that has been on every banker's, broker's and realtor's desk since 1981 — now on your iPhone, iPad and Mac. my12C brings the legendary 12C Voyager series financial calculator back to life with cycle-accurate emulation running the original microcode. Every keystroke, every display flicker, every RPN operation — faithfully reproduced.

WHY THE 12C NEVER WENT AWAY

The 12C is the longest-lived calculator ever made, and for good reason: its time-value-of-money keys, cash-flow analysis and RPN logic solve real financial problems in a handful of keystrokes. It is still the calculator used in finance courses and licensing exams around the world.
