Excellent 12C emulator

This has been one of my most frequently-used apps for the last 8 years. Colleagues are intrigued that my physical calculator exists on an app because they believe my RPN 12C is woefully out of date. Maybe so but not for me. The add-ins contained in the app are helpful, especially the currency converter. The one thing it doesn’t have that would be tremendously helpful is a tape with save/email abilities (same as exists in Windows app). There is no latency and calcs compute faster than on the physical device (of course).
I highly recommend this app, and particularly this version, and with respect to versions this is confusing; I would encourage the dev to move to one version with gradients of IAP although I’m not sure that’s possible once sales have been made. To wrap it up: this was one of my first App Store purchases for (at the time) my 3GS. Many of those apps drifted into the sea of abandon, but this app (and its developer) have withstood the test of time and responds quickly to questions.
Finally, if you’re a Windows desktop user you might be interested in the 12C desktop program by the same dev. It is a high-quality product that works particularly well with tablets or convertibles.

Must have app for financial professionals

I've been using this app for more than five years as a substitute for my 12c when I'm on the go. The most recent version from September 2017 is a solid long awaited update. I'm very pleased with the app and it's functional and recommend it anyone who works in finance. For the price you pay, this is a great value.

Super psyched this app wasn't abandoned!

I love this calculator. After years of RPN use, I can't use a regular calculator. I was worried because iphone kept giving me messages that this app needed to be updated or wouldn't work in ios 11 later this year. I assume this update will carry the torch to ios 11, and beyond. Well done!
