I use the RealCalc app that acts as an HP reverse polish notation calculator on my Android phone, although my HP 15C calculator purchased in graduate school (mid '80's) still work great.

Once your brain 'gets' RPN it's hard to use old fashioned algebraic calculators.

As a former CPA I found reverse Polish notation far superior when adding/subtracting columns of numbers.

A company that makes replica (sort of) HP calculators.

https://www.swissmicros.com/products

If you think these are expensive, note that HP 15C's are asking for more than $200 on ebay.
