I’ve built Quadratic Master back in 2009 when I was in high school and I was learning about quadratic equations in my math class. It is the first app I’ve ever built, and at the risk of sounding cheesy - it still holds a special place in my heart. Even though it was never a significant moneymaker, I’ve kept it updated throughout the years. And I’m happy to say that it has attained over 95.000 downloads to date. If you enjoy using the app, please consider buying the full version. Thank you.

## Quadratic Master Reviews in United States

### *---- "Does not work with iOS 26"
The input keypad is not complete after updating to iOS 26. That makes the app unusable
-- GPBike, 2025-12-11

### ***** "It does the job!"
Simple to use.   Never can remember the quadratic equation.  Now I don’t need to!
-- The Higgs, 2023-11-14

### *---- "I want a refund"
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.
-- Angel aka Phatmama, 2021-10-09

### ***-- "."
wouldn’t let me change addition to subtraction
-- Ranyenop, 2020-04-25

### ***** "Very nice, Caesar-Chan"
Nice. No ads. Nice.
-- Sans the Uru, 2020-03-16

### ***** "Helpful"
Helped me very much with my homework
-- Nishe2018, 2019-09-03

### ***** "AWESOME!!!"
This is a very good app. Very little ads. Very cool. Much fun on my math homework.
-- Kira Mac, 2018-07-07

### ***** "Only turned out one mistake!"
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!
-- WebsterE, 2016-10-01

### ***-- "Need to be able to use large decimals/scientific notation"
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.
-- Sam_sam_24, 2016-09-10

### **--- "PLZ FIX"
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
