Comments on Proportion Calculator for Android

★★★★★ Tahir Khan · Jul 29, 2024
Calculator is daily used in our daily use, and your application is very best for using
★★★★★ Vanshi Hathiyani · Mar 19, 2023
Nice and useful app this app pass me in 10th per ilium
★★☆☆☆ Conrad R · Apr 27, 2023
Not so clever! The devil is in the details. When I started to enter my 3 numbers the keyboard was forced into number mode, so I could not enter the 'x', because I couldn't get the alphabetical keyboard back.
★☆☆☆☆ paddypods · Aug 9, 2025
Doesn't work. After inputting three values, it should solve for x, but it keeps asking me to input x as well.
★★☆☆☆ Piotr Łapiński · Jan 8, 2023
App works great until it doesn't load properly. Clearing cache and force stopping app don't fix it. There aren't any fields and buttons are partially visible at the top of the screen. App is also missing auto calculate feature and locking the X in its field. You have to press the button each time for it to calculate.
