This app does not have the same keyboard feel, but it runs a lot faster. What takes 10 to 20 seconds to compute on the HP12C, this app spits out the result in a flash. To change the color scheme, press the ON (light bulb) button. ### 5/5 — Great for on the road *2021-02-27, version 1.7.2* I usually have my iPad in my briefcase, so with this app I also have a financial calculator with me. I have never been comfortable carrying my HP 12C in my briefcase. ### 5/5 — Calc *2021-01-19, version 1.7.2* Nice calculator if you are familiar with HP financial calculators. Graphics are weak (no colors). ### 3/5 — No trackpad support for iPad *2020-10-17, version 1.7.2* I love the HP12-c and using this app gives a very familiar feeling. Additionally, it is well optimized for multitask support. The only thing that is missing is the trackpad support. You cant click on anything with the trackpad/mouse for whatever reason. Probably an easy fix, but just a FYI if you plan on purchasing. ### 4/5 — Good but with a few bugs *2020-08-30, version 1.7.2* I rely on an HP-12C and usually have one in my bag, but this is a great substitute. I’ve tried other emulator apps but most are either ad-filled or expensive. This one is great but slightly buggy Main annoyance is the “EEX” button is coded incorrectly; for example typing “100 EEX 3” gives 10^23 instead of 10^5. ### 5/5 — Excellent, but not without minor bugs *2020-08-13, version 1.7.2* This is my go-to financial calculator. It is pretty much everything you get from an HP-12c. The only thing you should know about it is the SWAP (X<>Y) key is mislabeled- it looks like it got translated somehow to "XY". The key still does what it' supposed to do. It also doesn't have backspace but this wasn't on the original HP-12c so it's forgivable. It works under iPad multitasking- (very few calculators do)-- it has some font problems in multitasking but it's usable. ### 5/5 — Great replication of Hp RPN financial calculator *2020-03-03, version 1.7.2* For over 40 yrs I’ve used both my physical Hp12c calculators at work, with customers on the fly, and personally. So dependable, never broke. Now I use this App coz it’s so convenient and accessible. I’ve just had to get used to using it portrait mode too. I just say, “hey Siri open financial calculator App” and it appears 🤙 ### 4/5 — hard to see, found fix! *2020-02-08, version 1.7.2* Used to work great but one of the last updates changed the key colors to green, which is fine until you press the function key and they dim so much that you cant see the key labels. Supposedly they offer different color choices but I can’t find any way to change them. I’ve used this as a backup to my handheld hp12c for 5-10 years and was very happy with it until this change. Edit. if you hit ENTER then * it will toggle to another color combo. Keep doing that until you find one you like. ### 4/5 — Ok, but has font-sizing bug in multitask mode *2019-12-31, version 1.7.2* I like the clean and quick design, and the fact that it works in iOS 13 multitask and split-screen modes. There is a font resizing bug, however, in multitask and split-screen modes that makes it difficult to use in these modes. When switching to these modes the fonts get larger instead of smaller and the characters are chopped off at the bottom of the feature space making them somewhat unintelligible. This is particularly a problem for the numeric display because the decimal point cannot be seen at all. I would give it 5 stars but for this bug. ## Frequently asked questions about Financial Calculator Premium ### What does the Financial Calculator Premium app do?
