I haven’t fully gone through the app (the only reason for 4 stars instead of 5), but this looks GREAT! Returned the usable layout, and still delivering improved graphics, etc. Love it!!! Thank you for being so responsive! …………………….. …………. From earlier in April 2025: I have loved using this app for 10 to 15 years on both my iPad and iPhone. I use the app a few dozen times per day… mostly on my iPad at my desk. Today’s update messed up the interface on the iPad… buttons look oddly spaced, etc. I hope that gets fixed soon!!!! Yesterday i would have given 4 stars. Today i give 2 stars. I acknowledge it looks like a lot of work was done and it looks crisper, but it no longer looks/feels like a 12c on an iPad.","version":"3.1.0","date":"2025-04-30T00:00:00Z","rating":4,"app_id":503641946,"username":"Sjcurley","title":"Thank you!! - looks great on iPad today","country":"US","tags":["cross_platform_consistency","updates_and_maintenance"],"review_id":12603210685},{"content":"I want to thank the developer for its acknowledging my problems with this application. I received an email directly from the developer informing me of a just-released 3.1.1 version which I immediately downloaded. It appears to solve all of the problems I note below.\n\nUpdate lost all my stored information. Commas are where periods should be and vis versa. Hate the full screen layout on an iPad! The update needs an update and in a hurry!\n\nI have installed Version 3.1, and neither the layout, which is almost unusable, nor the commas being where periods should be and vice versa have changed! How can this continue?\n\nNOW, in addition to the problems previously noted above, the App forgets all stored numbers within hours of entry! After almost 50 years of using the original HP 12 C hand calculator through various versions of this calculator for iPad I have never had anything like this. The App is effectively useless. In fact, I have never had an app of any kind purchased in the App Store that had a single significant issue, let alone so many issues that the App was useless!","version":"3.1.1","date":"2025-05-24T00:00:00Z","rating":1,"app_id":503641946,"username":"RD2001A","title":"User","country":"US","tags":["performance_and_bugs","cross_platform_consistency","feature_requests","updates_and_maintenance"],"review_id":12694169399},{"content":"So since my senior level finance class in college I've been using my HP 10b when I don't have Excel available. I bought a real HP 12c recently, meaning sometime shortly after 1980, because it makes me look like Mr. Fancy Finance Guy. Having used algebraic calculators for over 100 years, I needed to practice RPN, so I got this app. Now I brag to all these 20 to 50 year old whippersnapper finance colleagues of mine about how I can use RPN and they can't because it confuses them since it's not the Excel IRR function or whatever the latest new Excel finance functions they've come up within the last 50 years are. They say RPN is faster than algebraic notation, but I like RPN simply because it's confusing and esoteric and being able to use it makes me better than everyone and I win. So there.\n\nI recommend this app.","version":"3.1.1","date":"2025-10-23T00:00:00Z","rating":5,"app_id":503641946,"username":"Captain SPACE","title":"Great App, It Makes Me Feel Fancy","country":"US","tags":["service","design"],"review_id":13301861975}],"related_apps":[{"app_id":946171077,"app_view_url":"/ios/us/elvis-pfutzenreuter/app/touch-rpn-calc/946171077/","country":"US","icon_url":"https://is1-ssl.mzstatic.com/image/thumb/Purple211/v4/bb/bd/a3/bbbda34f-ccf7-2e73-60f7-30f92e5630d2/AppIcon-1-0-0-1x_U007emarketing-0-8-0-85-220.png/150x150bb.jpg","name":"Touch RPN calc","os":"ios","price":{"currency":"USD","value":0,"string_value":"$0.00","subunit_to_unit":100},"publisher_id":463497848,"publisher_name":"Elvis Pfutzenreuter","publisher_profile_url":"/publisher/ios/463497848","rating":3.371980676328502,"rating_breakdown":[57,16,20,21,93],"rating_count":207},{"app_id":360256797,"app_view_url":"/ios/us/k2-cashflow-inc/app/10bii-financial-calculator/360256797/","country":"US","icon_url":"https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/8b/7f/e1/8b7fe1c0-b1ba-6992-4b5e-496c153d99c2/10bii_icon_composer-0-0-1x_U007epad-0-1-sRGB-85-220.png/150x150bb.jpg","name":"10bii Financial Calculator","os":"ios","price":{"currency":"USD","value":799,"string_value":"$7.99","subunit_to_unit":100},"publisher_id":337470779,"publisher_name":"K2 Cashflow, Inc.","publisher_profile_url":"/publisher/ios/337470779","rating":4.733031674208145,"rating_breakdown":[22,9,7,48,577],"rating_count":663},{"app_id":1481719060,"app_view_url":"/ios/us/angel-montana/app/ba-financial-calculator-pro/1481719060/","country":"US","icon_url":"https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/7d/7e/0d/7d7e0dd7-e3f7-2d9d-16bb-38c3def2897f/AppIcon-0-0-1x_U007epad-0-1-85-220.png/150x150bb.jpg","name":"BA Financial Calculator (PRO)","os":"ios","price":{"currency":"USD","value":399,"string_value":"$3.99","subunit_to_unit":100},"publisher_id":1479219211,"publisher_name":"Angel Montana","publisher_profile_url":"/publisher/ios/1479219211","rating":4.847682119205298,"rating_breakdown":[8,5,3,16,421],"rating_count":453},{"app_id":1464041112,"app_view_url":"/ios/us/factset-research-systems-inc/app/factset/1464041112/","country":"US","icon_url":"https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/ad/b6/ea/adb6eae0-dc99-160a-7f3a-88f2cdbf5631/AppIcon-0-1x_U007emarketing-0-8-0-85-220-0.png/150x150bb.jpg","name":"FactSet","os":"ios","price":{"currency":"USD","value":0,"string_value":"$0.00","subunit_to_unit":100},"publisher_id":379054683,"publisher_name":"FactSet Research Systems, Inc.","publisher_profile_url":"/publisher/ios/379054683","rating":4.558333333333334,"rating_breakdown":[14,7,6,17,196],"rating_count":240},{"app_id":780780002,"app_view_url":"/ios/us/ernest-brock/app/12calc/780780002/","country":"US","icon_url":"https://is1-ssl.mzstatic.com/image/thumb/Purple211/v4/dd/fb/10/ddfb10a8-d61a-1b02-8152-b86e4c0792cd/AppIcon-0-0-1x_U007emarketing-0-6-0-85-220.jpeg/150x150bb.jpg","name":"12Calc","os":"ios","price":{"currency":"USD","value":899,"string_value":"$8.99","subunit_to_unit":100},"publisher_id":289555912,"publisher_name":"Ernest Brock","publisher_profile_url":"/publisher/ios/289555912","rating":4.893406593406594,"rating_breakdown":[2,4,9,59,836],"rating_count":910},{"app_id":1613759385,"app_view_url":"/ios/us/r-l-m-software/app/rlm-12cx/1613759385/","country":"US","icon_url":"https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/46/89/df/4689df55-2521-f8d1-a048-a6d0acd3b762/AppIcon-0-0-1x_U007emarketing-0-7-0-85-220.png/150x150bb.jpg","name":"RLM-12CX","os":"ios","price":{"currency":"USD","value":0,"string_value":"$0.00","subunit_to_unit":100},"publisher_id":289639238,"publisher_name":"R.L.M.
