Calc-12E RPN Financial Reviews

It upsets me.

CambridgeMA

A single, brief glance at the version history of this “once great” 12-C emulator tells a story of intrigue (essentially no updates since 2014). Come on. What happened to valuing loyal and appreciative customers? From your own description of this product, there seemed to have been no small amount of passion you poured into this calculator when you actually introduced fun to Finance. You’ve lost that loving feeling. Get it back, please?

iPad Keyboard Fix

With the keyboard fix I now have a 4-star app that I can use both on the iPhone and iPad. Outstanding!

Solving for Interest/ROR errors

BrokenAero

I love the concept and features of this app, but I don't have confidence in the results. LIke "Edroid" I get inaccurate results wehn solving for Interest amounts and rates. Even the example for simple interest that is shown in the FAQs page of the author's Web site returned a different result. It would be nice to see a post from the author that an update is in process and that all algorithms are being proofed. Has anyone tried these calcs with Calculator12 from the same author?

IPad

Badger48

I’ve loved this APP for years on both my iPhone and iPad but that changed with IOS 11. Since then it has been temporarily patched but still needs tweaks especially for the iPad where the entry number keys are not spaced correctly. It has been 3 months and I hope you can find a fix soon, please. For now, I am down grading the 5 stars to 3 stars because it only fulfills 50% of my needs.

Outstanding!

Just what I was looking for and very polished. Best version of all the financial calculators out there. And with a bullet-proof pedigree! Thanks very much.

Perfect

This is a perfect recreation of an essential financial tool. Great job.

This is the financial calculator that I have been waiting for. As I watched the HP 12C emulators enter the App Store, I kept wondering why none of them took advantage of the iPhone's power and interface. The HP 12C is my favorite calculator, but I thought surely it could be improved on the iPhone. Finally, the 12E has done it. The 12E finally combines the 12C's familiarity and reliability with the iPhone's power and interface. Here are my favorite features: - email amortization tables and summaries of other calcs; - view the stack values at all times; - seperate screen for bond calculations; - larger keys that light up the chosen function; - instant calculations, no waiting

Slick Product

I'm actually a 17bii kind of guy, but can't find a software one. That said, I'm beginning to see why so many treasure their 12c's. Once you get past learning the 12c-isms this works great. Checked the calcs against a real hp17bii and on Excel. This program also has register displays to show entered data (also has stack view). Bigtime feature! I don't need to email amortization tables, but for those who do, it's pretty cool, I guess. The 12c (and RPN) is all about keystroke efficiency, and this seems to work just like a real 12c. Gets my vote.

soooo easy....

.....if you are familiar with the HP 12C.

Delightful...

All I can say, and if you use a 12-C you'll know what I mean, is that I feel like I got a friend back on my iPhone.
