Correction to previous review

The Janus Calculator appears to be a simulation of the HP-12C augmented with some HP-11C and the Black Scholes functions.

Apparently, the current edition is best version; the earlier version is not worth downloading. However, the current version only works on iOS 10 or 11. Therefore, this will not work on earlier iOS devices (like iPad 2 or iPhone 4S). That is why I deduct two stars.

Landscape mode makes the Janus Calculator resemble the HP-12C. Minor glitch, both iPhone SE and iPad Pro: "Flip" and "i" are not available in landscape mode. ("Flip" is how to switch between RPN and standard mode; "i" is access to help and other features). No stars deducted for this.

Easy interfaces

I'm old enough to remember the early handheld calculators, and what a difference it made to have a calculator with a full instruction set and a sensible interface. This app does it well, twice, plus offering a few useful constants. Bravo!

This is great! Just like my old HP.

Love this. Works on my ipad. Well done.
