HP 12C Platinum Calculator 4+

App won’t stay open, keeps crashing, please fix

It's a shame the App has not been updated to take advantage of iPhone 5's bigger screen size. It's frustrating to see unused screen when the calculator is so small.

If HP shipped a calculator with sticky keys I imagine they would do something about it. But here we have version 1.0 and I suspect that is how it will stay. The problem with this calculator is that the keys click loudly. You cannot turn the sound off. All you can do is lower your iPhone's volume while you use the calculator. I wanted to tell HP about this, but the support link simply goes to their homepage. As an iPhone version of the 12C Platinum it's just fine. Just like the real thing, with one niggle that the red and blue lettering is not as clear as the picture above. I don't believe that's a screenshot. The blue text is fine in the "numeric pad only" portrait mode, but just a bit too small in landscape mode. I imagine this is simply a limitation of the iPhone screen, so not in HP's control. Something to be aware of though if your eyesight is less than perfect. But that key click! I'm amazed that HP shipped without a "sound off" option. PS Have lowered to 2 stars from 3 as I have tried to give feedback to HP. There is no way to do so. I've removed the app and have bought a clone which was cheaper, had clearer keys and additional features. It's much nicer than this "original".
