15C Pro Scientific Calculator App Reviews

This is the best HP 15C emulator. Behaves and feels just like the real one. Anyhow, taking advantage this is an emulator and considering the original 15C could not store/save programs (i.e. you have to retype a full program each time you switch programs)l, PLEASE add programs storage/retrieval capability! This is a must.

I really like this calculator. It would be nice to have haptic feedback upon key press. This would help knowing that a number is pressed and not double pressed

Now my iPhone is complete! Now if I could only add it to the Control Center life world peace would be achieved!

Found this app and bought immediately. I felt like I found an old friend. Best machine ever for engineering calcs

This is a great app that works like my hardware version. I used the 15C long before this app existed but find I now log more time on this iPad version. I recommend this app without hesitation.

It even has the sound like an hp calc when you press the keys. Well executed app.

I’m so relieved that I can now have my scientific reverse Polish calculator on my phone. So far I’ve not found any problems, it seems familiar like the physical version and I’m very happy.

The HP 15C got me through four years of computer science, physics and electrical engineering. This is the same and it’s programmable just like the 15C. Cool beans.

g DEG 60 COS I get -.95, the RAD answer. But RAD is not on the display. What am I doing wrong? How do I get to degrees? g DEG does not seem to work. This is my only known question on my beloved 15C app. Thank you!!

Same as college days. Reverse Polish notation is the best. If you loved the device, this app is for you.

Works just as good as the original. And as long as I have my phone it is with me and ready to go!

This is an excellent app and HP 15C Scientific Calculator. I teach AP Calculus BC, and I use it often for my calculations. The user interface is clear and accurate, and the calculations are accurate. Highly recommended.

I have an iPhone 16. With the phone position sideways the calculator works excellent. My rotate vertical the image does not rotate. Also, there’s no access to settings as shown in the pictures. Lastly, it’s very difficult to close the app to move to something else. The normal swipe doesn’t work.

Slower than 1987 real calculator, how possible
