Comments on Hex,Dec,Oct,Bin(Dev Calc) for Android

★★★★☆ Jonathan Oksman · Aug 24, 2022

This is really nice! I like the idea of a calculator with multiple layouts. Really well implemented spite the lack of customization. If I could change one thing I would make the binary display more like a calculator instead of a long string of zeros and only show the significant bits. Otherwise, best calculator I've found for programming purposes!

★★★★★ Estelle McMurray · Jul 7, 2022

Great for color mixing. Just remember that you need an amount of BLACK equal to 255 minus the amount of the color for each color. If you have 100 parts RED you need to add 155 parts BLACK. Similarly, for 200 parts GREEN you need 55 parts BLACK. Same idea for BLUE. Remember to swipe LEFT or RIGHT to switch between CALCULATOR and Color MIXING functions.

A nice easy app. Hex to dec is used a lot in software, and it does it quickly and easily

★★★★★ Mark Kazdol · Oct 28, 2025

I actually use this app a lot for my coding. It's been a great help to me. Makes converting bin to hex much easier and faster too. Thanks much!

Cool to calculate big numbers but no way to paste any numbers in from the clipboard.

★★☆☆☆ Robert Stebler · Feb 17, 2023

I still have ads after buying the app. Would be four stars if it stopped showing me ads.
