It seems the same "old lovely" calculator that should never been discontinued by HP !

Awesome tool. I use ir a lot with excellent results.

I loved that calculator back in the 80s, still love it and this app is just bringing its magic to the iPhone: awesome!!!

Installed it. Could not enter a number. Yes I hit enter. Its gone now.

The moment I saw this I was so happy I love my 15-c and I love this app its perfect!

After running a number of comparisons between this emulator and a real HP-15C, I am impressed by the faithfulness of the emulation. The program must be using the physical calculators actual ROM. Well done.

I think RPN is great. Ive missed it since my HP calculator died. Is there an operators manual to help me get more out of this?

Amazing!

This is a good, general purpose scientific calculator. Once the user gets familiar with the odd syntax of the hp calculator operations, it works well.

I have been using an HP 15c for about 30 years. Im a dedicated RPN guy; nothing else is as efficient. I was delighted to find this app, which lets me always have my trusty 15c (or its virtual counterpart) always at hand!

This app won my day ! I have missed this calculator over a year. Since my 15C bought in 1983 died last year. Works just like my actual calculator did. Thank you for creating this app. It will be most used app on my iPhone 5S

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

I still treasure my 15C from the mid-1980s and now I can have it on my iPhone. I still have my HP manual with the programs for TVM. Simple to program the 100 or so lines into this app and the 15C is also a 12C! Excellent app!

I have had one of these since 1984, but dropped it and killed the display. This has restored the RPN world for me in a very correct nostalgic way. Get it!

Good simulator. Interface needs update to scale to newer hi-res phones. Performance needs to scale up to newer hardware.

This is a terrific emulation of the venerable HP-15C calculator -- the best one Ive found in the App Store (and believe me, Ive tried the others). Works just like the original, and it comes with a wealth of help functions -- pressing the Help button reveals the original User Manual and Advanced Functions Handbook in PDF format, as well as manuals for a number of other HP calculators. And its always as close as your phone. I gladly give this app 5 stars!

Lack the option of simple calculator with the iPhone upright. Falta a opção da calculadora mais simples com o iPhone na posição vertical.

I love HP calculators and RPN entry. Works really well. I wish there were an HP-41 available.

Works well. Just like the original calculator.
