I had previously left a negative review. They fixed the problem, now works great. Beautiful interface, fast, and just like the 12c I have used for years.

Was ready to spend $70 bucks for a replacement 12C till I saw this app. It works fantastic, & now have the calc with me at all times. I know, I am a dork to get excited over a calc app, but it is very cool!!

I work in finance and this is a great app. I no longer take my 12C with me--I just wip out my iphone everytime I need some math on the fly. Have never had a problem with it. The design is perfect.

This application is top drawer! I reviewed this app last November - shortly after its initial release - and I listed several problems that I had encountered with the accuracy of certain results. All of those issues appear to have been successfully addressed. After six additional months of use I now have complete confidence in this app. I'm also impressed that the author has continued to add highly useful functions and functionality to this app and has included them as free updates.

The HP 12c is a standard - these folks kept the standard and improved it dramatically. HP simply recreated their calculator on an iPhone - didn't give any thought to improving it. In my mind, my "flagship" differentiator is the cash flow viewer/editor... if you've never tried it it's slick IMHO. It allows you to see your cash flow entries as a cash flow diagram, and edit them (including adding and deleting individual cash flows) using the visual format--with the HP you can only delete the last cash flow and to do so you have to change the value of the n-register and you can't add a cash flow in the middle of your series. If you messed up entering the cash flows, you have to start over from CFo. Emailing results, in particular amortization tables and calculations dealing with cash flows and one-tap access to the forum's FAQ page is very helpful - these guys did it right!!

I purchased this when if first came out and have found it to be one of the most useful apps available. I use it all the time and it has since completely replaced my HP 12c. The large buttons work great and the functionality is superb. I haven't spent a huge amount of time on the extra features but have found them useful when I needed them. If you're thinking about a 12c for your iPhone, this is the one to get, hands down.

One of my most used apps on the phone with one of the ugliest icons in the app store. It would make my day when this finally got fixed.
