15C Pro Scientific Calculator App Reviews

Still love it. Works just like a 15c Btw for the other reviewer, RPN calculators dont have an "=" button, they dont need it. Nice calculator works just like a HP.

Just like the real deal I had in college. Excellent.

Works great, looks good on the iphone6+

Excellent app so far. I used the HP15 for years. (Still have it). This is a very accurate recreation of that model. Nice touch to have the information from the back of the original under the "help" button.

I bought this a few years ago, but am only now rating it. Im a professional engineer. This puts my trusty HP-15c ALWAYS in my pocket.

Ive loved the RPN HP calculator since the 80s and now I love this app. Math nerd and professional engineer loves her "new" 15C. Its a dream come true, thanks a bunch.

I use this more than anything else on my phone. The app functions beautifully.

I still have the hp15C that I bought, um, a long time ago. It still works great. "I dont always leave my hp15C behind, but when I do, this emulator is my choice instead!"

Short of having raised keys, its hard to imagine how this emulation of my favorite calculator could be any better.

This is a great emulation of a great tool for scientists and engineers! I am so happy to see that my iPhone can function as this calculator!! I got a degree in math and physics during the era when HP was cranking out amazing RPN calculating devices that were unmatched by any others! Taking USAF Orbital Analysis training as a new Lt using my HP15C, I was so far advanced with this calculator at the time that they actually switched to this model for those students. Then in my 30+ year career as a rocket scientist orbital engineer I never gave up my use of whatever HP calculator was the latest and greatest at the time. Welcome back to a truly great tool for my iPhone!!

Once in a while you come across an App that exceeds expectations. This App certainly does. It is a perfect emulation of the Classic HP calculator. Good job, developers!

Excellent! Just as if you had the original in you hand! I shared with an accountant who had three of the originals in different places...and now has just this one. So much more convenient!

Its great to know I have a true back up for the original 15-C that I have had for over 31 years! Thank you

I found it very difficult to locate a full function scientific calculator. Many apps have paywalls and sacrifice scientific function for good looks. This app truly is the legendary HP15c on your phone. Worth every penny.

I grew up on an HP 15. This is just like home. No complaints. Well worth the price.

Just like the original - what more is there to say.

This app is fantastic and lets me conveniently carry my calculator with me everywhere

Bravo!

I ran a program that used every bit of memory. This emulator is just like the original 15c (except the font looks different). It could done the original one better by having a listing of program steps for review.

Works perfect. Well worth the cost.
