{"game_intel_data":{},"featured_reviews":[{"content":"Hewlett Packard has a loyal following and a reputation for highest quality - and for correcting problems when they arise. (Early HP scientific calculators actually were recalled and replaced when a tiny bug was discovered.) But a business calculator that makes elementary-school math errors (e.g., in squaring a negative number) is unforgiveable!\n\nThe calculator on which this app is based goes back to 1981, and among financial wizards both old and young, it is still the gold (well, platinum) standard! This iPhone version appears to have been introduced in 2009, which should have allowed HP plenty of time to get it working credibly under OS 3.1 or later.","version":"1.0","date":"2014-03-03T00:00:00Z","rating":1,"app_id":328224790,"username":"Education Technology Review","title":"Embarrassing!

This app captures that legacy with care, accuracy, and respect.\n\nIts interface remains true to the original. No gimmicks. No distractions. Just the refined layout and reliable performance that made the 12C a standard in finance, banking, and business education worldwide.\n\nSome reviewers, perhaps unfamiliar with what they hold, have rated this app poorly. That is not a reflection of the product—but a misunderstanding of its purpose. The HP 12C is not meant to entertain. It is meant to perform. And it does so, brilliantly.\n\nTo the developers: thank you for preserving the experience. To the users who know the value of this tool: let your five-star reviews speak louder than the noise.\n\nThis is excellence, reissued.","version":"2.3.4","date":"2025-05-21T00:00:00Z","rating":5,"app_id":328224790,"username":"tommetrick","title":"A Financial Classic, Flawlessly Recreated","country":"US","tags":["sound_and_music"],"review_id":12680540809},{"content":"As of October 21, 2017 this app works great in iOS 11.
