One of a kind

This is *the* ultimate "calculator" app. It's too bad this is the best word we have to describe it. If you work in any field requiring moderate to complex computation you will find it to be indispensable before long.

It's like a transformer that can be infinitely tweaked down to the exact iota of customization desired, yet still able to flip back to simple calculator layout/mode (for common use) with just a button press. This is thanks to layout templates which provide excellent starting layouts with complete edit flexibility, and the option to quickly switch between them. There are also customizable style templates with around a dozen well crafted styles included.

It's completely seamless when used on multiple devices. I have it on iPhone, iPad as apps AND as widgets, and also on OS X. They all seamlessly sync so I can start on one device and pickup from another with tape and history intact, making it the most accessible and ubiquitous calc app in the entire App Store!

The developer is also extremely dependable. I've had this app for maybe 6-7 years and steady updates have never lulled. BTW, I am running it fine on my iPhone 6 Plus and have in fact never seen this app crash once in half a decade, on any of the platforms. So bugs should not be a concern... Must be user error.

Just about my favorite app!

Yeah, a calculator app, of all things, is one of my 3-4 favorite iPad/iPhone(/Mac) apps, the others being NHL, Western Digital My Cloud, and Numbers.

The RPN mode is flawless, same as HP's implementations going back to the HP-35. Having an unlimited stack and being able to easily view all the entries is wonderful.

I do wish there were an "HP-65" programming mode, one that used exactly the same instructions that you would issue manually to do a computation; the current 2- and 3-address programming model requires mental gymnastics to transform the manual execution model to the programming model, and makes programming it relatively slow.

Great Calc, needs 1 thing

For those of us who prefer an RPN calculator, this one has been one of the best. The only thing it desperately needs is when we make a mistake, it would be absolutely wonderful if it had the option to report an error such as "too few arguments" like a regular RPN calculator does.

We need a notice when we make an error so we don't keep going, but the vibrate is awful. I know we can shut the vibrate off, but then there isn't a good error notice to stop us and recheck our work. Please include an option for an error message in place of the vibrate.
