One suggestion would make it perfect hp emulator: haptic keyboard feedback. Add this and this will be perfect! ### 3/5 — Looks good - need haptic feedback *2023-10-18, version 2.546* The calculator looks great. You can toggle the sound on and off, however I would really need haptic feedback on the keys to simulate better the experience of the original. ### 3/5 — No Split View *2023-06-27, version 2.546* I’d give it 5 if it had a Split View on the iPad. Asked but never got a response. ### 4/5 — 12c *2022-10-27, version 2.546* Being a banker and having app-12c calculator and now this app on my phone has being a great help. There’s one thing I wanted to use this App and that’s on my Mac. I would have to buy the App again for Mac. I think that’s not fair. ### 2/5 — funcao data com erro *2022-09-26* nao estou conseguindo tambem a funcao data errro8. funcionava normal ### 5/5 — Nice *2022-06-07, version 2.546* Accurate, has the 12c look option and it’s a great calculator. ### 5/5 — Fantastic !! *2022-05-20, version 2.546* I use it almost everyday to support my activities of an individual investor. ### 5/5 — Great! *2022-04-26, version 2.546* Just like the HP!! ### 5/5 — Best 12C ever *2022-03-19, version 2.546* It works fast and stable. Get exact say result as the real calculator. All my classmates use this app. Much better than HP app. ### 5/5 — Just looks different than my old HP-12c *2022-02-17, version 2.546* Great app and no need to carry around another device!! Highly recommended!! ### 5/5 — Great emulations *2022-01-20, version 2.546* After nearly 40 years the number 9 key on my 12c doesn’t always register about a third of the time. Easier to switch to this version than take it apart to try to fix it or to unlearn RPN habits. The 15C is available in a bundle for an extra £2 as well, and having never owned one, that was a bonus to try out, even though I remain a “2 decimal places good, 4 d p bad” person. Soon get used to it as everything seems to work the same as on the real thing. Having the handbook online is another bonus as I doubt if I could find mine easily if I wanted to do something out of the ordinary. ### 4/5 — It’s good *2021-12-10, version 2.546* Better would be bundled with the Mac app and maybe and instruction set. ### 5/5 — Great app! *2021-11-04, version 2.546* Looks and works just like the real thing! Well worth it ### 5/5 — Just like the real thing *2021-10-26, version 2.546* I started using the 12C about 25 years ago. This version is identical to the physical one, or even better. It’s a MUST download for anyone who wants to get percentages quickly, or for those who want to do more advance stuff like annuities, yields, NPVs, etc. ## Most critical reviews (10 lowest-rated) ### 1/5 — No support *2024-11-16, version 2.546* App hasn’t been updated in 4+ years. Stored registers will 0 out for no reason whatsoever. Stored number in register will be exponentially higher when you recall it, again, no reason whatsoever. Sent a support ticket in years ago and no answer. Do not waste your money. ### 1/5 — Won’t work on iPad *2024-02-17, version 2.546* Calculator opens at about twice the size of my iPad screen making half the buttons inaccessible. No resize of scroll function available. Worse, no way to get refund! Do not purchase for iPad! ### 1/5 — Point doesn’t work *2022-06-03, version 2.546* This is horrible. Beware. Trying to insert a decimal is nearly impossible because the period won’t register. Shouldn’t have cheaped out because now I have to buy the HP anyway. ### 1/5 — Calculadora lenta *2022-01-29* Gostaria de cancelar a compra, não serve para mim , muito lenta em cálculos simples de juros, fica em running….. ### 1/5 — A calculadora não aparece como na foto as teclas com destaque *2021-10-19* Fica confuso, as teclas não aparece como na foto, é ruim a visualização ### 1/5 — Vicinno Financial Calculator *2021-03-29, version 2.546* I was ripped off. Wish the App Store would get their act together and Identify those apps that only work on designated devises. I purchased to financial calculators for my Apple 10X and neither works because of the new operatiing system. This app said that it had worked out its bugs in late 2020 so I took a chance and got burned. Furstrated Real Estate Agent. I need something to calculate monthly payments. ### 1/5 — Very Disappointed *2020-12-11, version 2.546* I am very disappointed with this calculator. I got the app to help me calculate mortgage payments since I am a Private Mortgage Banker but I keep getting the wrong payments. I follow the same exact steps I with my HP 12c financial calculator but it does not work. ### 1/5 — Não abre mais *2020-05-05* Não está mais abrindo no iPhone 7plus ### 1/5 — Divisão de está dando valores incorretos *2019-09-03* Quando divido 2.800 por 480.000 está dando valores errados ,01 Erro básico😡😡😡 ### 1/5 — Why Change What Worked? *2019-03-24, version 2.544* The pictures show an HP-12C look on the left, and that’s what I bought. A few months ago, I noticed that the look had been changed. Now it looks like the second picture shown in the App Store. I didn’t like it, but I figured so long as it worked I’d still be happy. But it doesn’t work. The keys have become “sticky,” and as a result you can’t just tap keys and keep moving as had been the case. I would like the old HP-12C look, but particularly I would like to see the calculator work correctly. I would have rated it a 5-star App prior to your change. ## Most praised reviews (10 highest-rated) ### 5/5 — Used this app … still 5 stars *2026-08-04, version 2.546* I love this app. Love the HP 12C calculator, and this app is exactly like my clicky one at home. Worth the coins!!! ### 5/5 — Just like the original *2026-03-06, version 2.546* I just started working on an ms finance and bought this app. I also just bought an original hp 12C. This app works great. It's a dedicated financial calculator. If your reading this you probably know that though... Does all the same calcs the same way and also looks great! I highly recommend this app if you are looking for an hp 12C calculator!!! If you are just looking for a "plain Jane" calculator this is NOT for you! Now does not open in ios26.3 ### 5/5 — Top *2025-02-09* App muito bom ### 5/5 — Love it *2024-10-15, version 2.546* Just bought the App. Really like it! ### 5/5 — Thankful it's available *2024-05-18, version 2.546* Got my first HP in 1973, an HP35. Yhe Reverse Polish Notation makes everything SO much easier than direct algebraic entry. It is absolutely gabulous to have this app available. ### 5/5 — Still faithful after so many years *2024-03-05, version 2.546* I’ve been using this app for many years. It is one of my daily go to apps. No exaggeration. I use this every single day. If you’re familiar with the HP-12c, you’ll be completely familiar with this. I’ve never had a problem with it. It just works. A special shout out to the developer. Years ago, they gave the app a new, sleek, flattened look. I wrote to them about the fact that, due to my vision, I couldn’t see the demarcation of the buttons. The developer restored the original look as an option, which you can find under settings. Thank you for maintaining that. Some may be put off by the unfamiliar way of doing a simple calculation using what is called RPN notation. In school we learned PEMDAS-based arithmetic notation to enter numbers for calculations. Try spending a little time learning RPN. It helps get rid of parentheses and you control the order of arithmetic operations. It’s better for any multi-step problem other than adding a simple column of numbers. ### 5/5 — Excelente até o momento *2023-05-25* Muito bom até o momento ### 5/5 — J’ai retrouvé la HP12C des 80’s ! *2023-04-11* Quel plaisir de retrouver la HP12C de mes débuts professionnels et sa notation polonaise inversée ! avec les mêmes touches vintage quel plaisir 😊🙏 ### 5/5 — Wow *2022-11-24, version 2.546* Great function and fast, works just like my HP 12c ### 5/5 — Just like the HP12C *2022-09-08, version 2.546* Having used 3 different HP12C calculators over 40 years in finance they are like my right hand in familiarity. This app is virtually the same in functionality. The only differences are the tactile feel of the keys and being able to use the ever-rugged HP12C case as a light duty hammer. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
