12Calc 4+

In an earlier review I gave this phenomenal app 5 stars but wanted to give it 100. Now, I want to give it 1,000. Without any doubt, this is the #1 calculator of its kind on the market in this CPA's opinion. I use this every day for a wide variety of professional and personal reasons. In addition to doing all the HP 12-C calculations, it has templates for leases, loans, time value of money, multi-year financial ratios, foreign exchange calculations, etc. I use the conversions feature to help me with calculations necessary when I fly general aviation aircraft. One of the best, most useful features is an electronic "tape," which, amazingly, can be e-mailed as a PDF file for printing if need be. This makes the app substantially more valuable than any physical calculator or any comparable app.

When I bought this app for my iPhone, I expected to have to pay again for my iPad, but, no, I could download it onto my iPad for no additional cost. This calculator is outstanding. The developer, Ernie Brock, is a genius. He keeps making his app better and better all while staying ahead of Apple’s iOS changes that impact the functionality of the program.

I recommend this fantastic app HIGHLY. It continues to get me through CPA seasons, and it makes calculations of pilotage and dead reckoning much easier when I plan cross country flights.

The updates on this app keep it at the top of my list of most used apps on my iPhone and other Apple devices. I have always owned at least three HP 12C handheld calculators since these came to the market decades ago. I still do today but now that I am on my iPhones and iPads most of every waking hour I find it so convenient to be able to click on Ernest Brock's 12Calc on my iPhones and iPads while working numbers on these devices. I have been a user of Ernest Brock's 12Calc from its first appearance and through its periodic updates with new features as Mr. Brock has again done with this superb 12Calc Version 2.3! I am now 76 years old and since these came out in the market I have used and recommended to family and friends both the HP12C handheld calculator and Ernest Brock's 12Calc app. I will continue to use and recommend these to anyone looking for timeless products that are classics in their industry. Good job, HP and Ernest Brock! Your excellent products enhance each other like supportive partners, which is how I view and use your products.

This is the best financial calculator which I have ever used. For example: The financial registers display above the buttons. You can get a tape if you want. There are associated programs where you can get results printed such as an amortization schedule. It has a conversion feature which I really find handy. It will even convert currency. The users manual is really great. I have recommended this calculator to many of my friends and many people at our office use it. I have tried several of these financial calculators and this is by far the best. Thom Cooper
