★★★★★ 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.
