Super vec!!! ### 5/5 — Robin Budík *2010-06-08* I agree, really useful app and the brst one on quadratics and calculating on the entire appstore!! ### 5/5 — Pro středoškoláky užitečná to pomůcka *2010-06-06, version 0* Ať už pro středoškoláky či studenty víceletých gymnázií je tento program jako stvořený. Ocení jej zejména mládež ve vyšších ročnících, především Ti matematicky méně zdatní při začátcích probírání kvadratických rovnic, nerovnic a funkcí. Aplikace navíc obsahuje i zabudovaný návod pro výpočet řešení rovnic a teorii ke kvadrantickým funkcím. Nápad opravdu geniální, a vzhledem k tomu, že aplikace pochází od českého autora, plně v češtině. Doporučuji! ## Most critical reviews (10 lowest-rated) ### 1/5 — Does not work with iOS 26 *2025-12-11* The input keypad is not complete after updating to iOS 26. That makes the app unusable **Developer response:** Thank you for letting me know about this. Quadratic Master is now fully updated for iOS 26, including a custom keyboard with the minus sign. Thank you for your patience. - Lukas ### 1/5 — I want a refund *2021-10-09* I got this app in the hopes of getting extra help. Sadly all I got was an app that was not working. I can not enter the problem I need help with. Also, it's not showing up in my app library. I know it's not my phone because it's a 12 mini and less than a month old. ### 1/5 — Bad *2016-02-19* Wouldn't let me open the ap ### 1/5 — Pictures are just show *2011-10-31* App. Works but the nice pictures are just for show and do not reflect the ability of this app. Any of the free apps is as good as this one. ### 1/5 — Blows *2011-04-05* Does not graph quadratic functions ### 2/5 — PLZ FIX *2016-04-04* The app idea is awesome for students learning this stuff, that is why I rated it 2 stars instead of 1. But the issue is it will not open, it keeps crashing when I try to open it ### 2/5 — How do you change it to vertex form *2012-10-08, version 2.0.1* I need to know how to change the standard formula into vertex form ### 3/5 — . *2020-04-25* wouldn’t let me change addition to subtraction ### 3/5 — Need to be able to use large decimals/scientific notation *2016-09-10* I like the set up and it is very simple, however you cannot put large decimals. I won't be able to use this app since a lot of the problems I need to solve are large decimals/scientific notations. ### 4/5 — nice  *2010-10-23* cooler icon maybe? but still great ## Most praised reviews (10 highest-rated) ### 5/5 — It does the job! *2023-11-14* Simple to use. Never can remember the quadratic equation. Now I don’t need to! ### 5/5 — Very nice, Caesar-Chan *2020-03-16* Nice. No ads. Nice. ### 5/5 — Bad app do not get *2020-03-04* Made my cry so I kicked it in the shins ### 5/5 — Helpful *2019-09-03* Helped me very much with my homework ### 5/5 — AWESOME!!! *2018-07-07* This is a very good app. Very little ads.

Quite handy when solving complicated equations. ### 5/5 — Only turned out one mistake! *2016-10-01* Seriously saved me when I was super late for class, simple and easy to use. Even lets tells you how to solve on your own~ only mistake was the it flipped the positive and negative of a specific factor so its always good to check your answers! ### 5/5 — Useful *2015-06-11* Awesome ### 5/5 — Very good.
