11C Scientific Calculator App Reviews

Very useful for calculating world domination quotas. Plunger arm interface would be a nice future revision.

Works just like the "real" one. The only thing that would make it cooler is to use 3D Touch to make it feel like the buttons click.

Works just like my good old 11C - which I still have BTW, but much easier to just use the app than dig out the old workhorse. Very happy with it - I got through most of my career plus my CQE exam with the 11C so was happy to discover this app.

On a 6 or 7, its almost the same size as the original calculator.

Very nice calculator exactly like my regular HP 11C.

Its good, but could be better !

Feels like the real 11c

I could not find the = button or the clear button or the on button at first.

Love it, reminds me of the old days!

If you used to have this great calculator youll like it.

Love this app. Feels just like the old HP calc. Works great even on older iPhone4

Great calculator! A legendery calculator moe in my iPhone. Thanks!

Perfect tool! Cant function without after growing up using RPN. Still the fastest way to crank numbers. Nothing beets the old HP calculators!

Works just like my calculator. Love it and use it as often as I use the real HP calculator.

If only they could reproduce the tactile click of the buttons! But I like having some of those functions back. Thnx.

My HP 67 died many years ago now I have this. I am so excited, it works just like it should. I burn TI kids in their tracks. It sure dates me but man is it powerful.

Asside from a 0 key that either doubles or misses, my HP 11C from Physics II is still going strong. This app is just like it, minus the zero key issue. A minor difference is that to get out of f/g mode, you need to go to f-prefix to clear back to standard as there are functions for the ON key-- menu and help. I often work with geographic coordinates, going from DegMinSec to Decimal degrees and vice versa, so having that feature is most welcome. Asside from the missing HP logo, the only differences are the size (because of the iPhone), no tactile feel (as expected), no battery placement chart on the back (not needed) nor does it have my name engraved on it as well as the dots I painted on for the resistor color code. Would be nice to zoom and pan the screen to enlarge the buttons, but is workable. Based on this purchase, I am also purchasing Vicinnos 12E financial calculator. Viva RPN!

Just like using the real thing! Saves taking around the old "relic" and gives me a replacement should my original calc ever fail. Good job!

All the HP calculators are amazing. This Pp just makes it available wherever my phone is!!!!!!

Good job. I use it every day at least once.
