Excellent scientific calculator with step-by-step solutions, symbolic algebra, graphing, equations, integrals and derivatives.
The calculator has globally more than 50 million downloads and 250 000 five-star ratings.
You can write expressions in a natural way and watch your calculations. The result is displayed as a number, simplified expression etc.
An expression can also be entered from a photo. Take a picture of a handwritten or printed expression, and the calculator recognizes it and inserts it into the display, ready to be edited or evaluated. (premium)
A step-by-step solution shows how an expression is solved, one step at a time, from the entered expression to the final result. Every step is explained, so you can see not only the result, but also the way to it. (more detailed steps are premium)
Calculation details give you extended information about the result - alternative forms of the result, all complex roots, the unit circle, properties of a function and more.

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!
Love the app, just one small problem
tahamasihi
It’s one of the best calculator apps available and i I’m considering to buy the pro version, The only complaint I have is that i use the calculator in slide over mode on iPad but the apps window size is too large and it can’t be scaled down if you add this feature it will be much appreciated
Developer Response
Thank you for your kind words and for considering the Pro version! We’re happy to let you know that, starting with version 12.0.8, the app fully supports iPad multitasking and adapts to smaller window sizes, including Slide Over. We hope you enjoy the improvement!
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.
- Step-by-step solutions for new topics: absolute value equations, inequalities, infinity, limits, integrals, hyperbolic functions, matrices
- New integration methods
- Double factorial function
- New language: Arabic
