Comments on Calc4Key: Calculator Keyboard for Android

★★★★★ Viveka nand · Jan 31, 2022
When we need numeric key then it works with the best performance.
★★★★☆ Mike Holman · Jun 24, 2025
It does as described. Basic 10-key keyboard. Would like the ability to customize key colors
★★★★★ SajidAli Chawdhry · Jan 30, 2024
Greater useful while using other app with this immediately calculation can be done having calc4key is an artwork with smartphone
★★★★★ Saurabh kumar Mishra · Jan 1, 2026
Once you start this, your calculator switching problem resolved
★☆☆☆☆ Angom Puru Singh · Feb 25, 2025
After calculation can't revert back to regular keyboard. There is no option to revert to regular keyboard. There is no keyboard symbol under the keyboard. A waste of an otherwise beautiful calculator keyboard.
★☆☆☆☆ Terry Masri · Jul 23, 2022
Does it even work? I followed instructions and enabled Calc4Key in the settings and restarted phone, and yet I don't see a keyboard symbol under the keyboard nor any other way to switch to Calc4Key from regular keyboard.
