HP 15C Calculator Reviews

Back to five stars!

Thank you so much for the latest update. The display is finally back to normal!!!

The Original Engineering Calculator

HP created an actual emulator of the ROM of the original HP-15C. Therefore, guaranteed to be faithful emulation of the original! As is the case with the other HP Voyager series calculators. Excellent! My only wish is that HP would release the HP-16C computer scientist calculator as well so I can complete my collection!

Misleading

AlphaT1

Shows scientific functions but when purchased, they were not there.

Great but has an annoying bug

Steve!:D

Display in portrait orientation is misaligned. “LCD” numbers show up on the “brushed steel bezel” below the display. Ok in landscape orientation, but super annoying!

Requires Update

Display is still not correct in “portrait “ mode. Update: New: the display numbers do not line up in the display properly Now I get a message that this app soon will not work in future iOS versions unless the app is updated. The developer website, HP, is of no help. I like this application, but my iPhone is generating a message that reads that the app can have a negative impact on the performance of the phone unless it is updated.

Pretty, powerful, some bugs

This is a full-featured and good looking emulation of my original and beloved HP 15C Scientific RPN calculator (I still use a Limited Edition version today). That said, it’s a little buggy in annoying but harmless ways. For example, in portrait mode, the displayed numbers aren’t actually positioned in the display (on both iPad and iPhone). And results from running or numerically integrating a programmer function leave the displayed numbers in a flashing state.

Need an update for iOS 13

I love this app but the latest update messed up the number display on the iPhone 11. Hopefully fixed soon. 5 stars when fixed!

15C bait and switch

THLambert

I just purchased from Apple Store for about $15 the HP 15C as pictured. When it loaded, it was definitely NOT a 15C, more like the very old HP45. Someone should check on this and make it right. It appears to be an error in the Apple Store software. Consider this a PROTEST of payment!

Newest release has a bug 2.3.2

This calculator is great but the latest revision has a bug. In portrait mode the numbers appear outside of the calculator display on my ipad pro. Please fix this. And please develop and offer a 48GX application.

V2.3.2 numerical display off location

I absolutely love this calculator but your most recent 2.3.2 update displays the numbers outside the box in portrait mode!
