Comments on Simple Calculator - Fothong for Android

โ˜…โ˜…โ˜…โ˜…โ˜… Westley Silvers ยท Sep 9, 2025
Very good ๐Ÿ‘๐Ÿ˜Š I can now help my big brother with his homework without him snapping at me
โ˜…โ˜…โ˜…โ˜…โ˜† ใƒ„sentinels ยท Sep 23, 2021
A fantastic ui but if the length of the calculator buttons can be editable it would be even better.
โ˜…โ˜…โ˜…โ˜…โ˜† Anderwriter ยท Feb 20, 2022
Nice, but it lacks one thing: If you're trying to calculate a tip (for example), and you type "20+15%", it shows the total as "20.15". (Obviously that's not right.) For the correct result, you must type "20.00*115%" (as 115% = the original amount plus 15% of it). The characters on the "keys" could also be larger, at least as an option. Maybe these can be improved.
โ˜…โ˜…โ˜…โ˜…โ˜† Deano ยท Mar 11, 2023
This is ok, especially if you need to use 2 calculators like me ๐Ÿ˜… one complaint though, the haptic feedback is too soft!
โ˜…โ˜…โ˜†โ˜†โ˜† Mika M. ยท Jul 17, 2022
I like it, but the haptic feedback doesn't work. There's a setting for it, but the setting doesn't do anything.
โ˜…โ˜†โ˜†โ˜†โ˜† J S ยท Sep 3, 2022
J S Wants network access. There are better, open source calculators that don't want unnecessary permissions.
โ˜…โ˜†โ˜†โ˜†โ˜† Henrik Helmius ยท Jan 29, 2022
If you male a calculator app you may want to make sure that it actually calculates correctly and doesn't lose precision in floating point calculations. 3.225 - 2.7 in this app is not 0.525 but instead 0.5249999999999999.
