Excellent App and Sci Calc
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.
Great Tool
Works just as good as the original. And as long as I have my phone it is with me and ready to go!
Reliable through four years of use
Same as college days. Reverse Polish notation is the best. If you loved the device, this app is for you.
Stuck in RAD?
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!!
Just like college
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.
My 11C finally crashed
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.
Works like the old fashioned RPN calc
It even has the sound like an hp calc when you press the keys. Well executed app.
