Good app. However, I noticed you said everything on the premium version is available on the free version. Only no ads for $7.99 I would suggest you add a few capabilities on the paid version not available on the free version just to make the paid version more attractive. That way people who pay get more features while you get more financial reward for your app.
Developer Response
Hello! Thank you for the idea. We are working on bringing more features that will be Premium - most notably the app themes. For the moment, that was not the priority though, but understand it will make more people accept the value. All the best!
Still the best

I’ve tried tens of calculators on both the Google App Store and the Apple App Store. This calculator remains the best. I’ve been using it for many years now, and strayed from it to use a few others, but I keep coming back to this one.
Great HP Calculator Emulation
AirWolf526
I have several HP calculators and this emulation is excellent, and accurate. Operates just like original HP calculators, includes Reverse Polish Notation, Expressions, and complete repertoire of scientific functions. It is my go to when I do not have my original HP calculator handy. Highly recommend this app.
Customization!
KZapp720
With the custom functions options this has become my goto calculator for non trivial calculations. Would love the option to expand on that by allowing custom infix operations!
- Reverse Polish Notation (RPN) mode
- Graph up to 20 functions at once
- Improved partial fraction decomposition
- New detail: Expression roots
- New languages: Dutch, Vietnamese
