2025 Editor's Rating
EXCELLENT User Rating

The RPN-70 HD serves as a comprehensive and photo-realistic simulation of the HP-70 financial calculator, a classic model from 1974. It adeptly manages functions such as loan amortization, savings plans, depreciation, and more, ensuring usability for a range of finance-related tasks.

User feedback has been largely positive:

  • "It's challenging to find a decent calculator on iPad; I recommend trying this one."
  • "I typically don’t write reviews, but RPN-70 has truly impressed me. Apple should categorize this app under Education in the App Store; it’s essential for any college-bound student. It stands out as the best HP emulator available."
  • "An exceptionally well-engineered calculator app, and it's free!"
  • "This is an outstanding financial calculator that closely mirrors the original HP-70, providing accuracy down to the penny."

Key features include:

  • Photo-realistic aesthetics based on the original device
  • "Live" register view when in landscape mode
  • Animated keys accompanied by adjustable click sounds
  • Comprehensive implementation of all HP-70 functions and operations
  • Optional simulation of the HP-70’s computation time
  • Ability to correct erroneous entries by swiping left across the display
  • Cut, copy, and paste functionality for display values
  • Visual indicators for tracking stored input parameters (optional)
  • Display of stack just below the main display (optional)
  • Ten non-volatile memory registers (optional)
  • A built-in manual featuring numerous examples

The HP-70 was discontinued within a year of its release, making it one of the rarest calculators now difficult to locate in any condition.

Note: The RPN-70 HD accurately simulates the vintage HP-70, verified against an actual device using examples from the HP-70 manual's Applications Cookbook section. Occasionally, what may seem like an app bug could be an inherent quirk of the original HP-70 device.

Important: The HP-70 requires precisely three input parameters from the top-row keys, with at least one being either "n" or "i". Therefore, using PMT, PV, and FV as input parameters simultaneously is not permissible.

A version for the iPhone known as "RPN-70 SD" is also available.
