About T-Calc-Lite
A simple and easy-to-use calculator app that combines two calculators into one.
Calculators are displayed side by side when the screen is horizontal, and vertically when the screen is vertical.
In addition to being able to perform separate calculations with each calculator, calculation results can be also copy and paste with one touch, so you can perform other calculations during calculations, making it even more convenient to use than you might imagine.
There is also a paid version without ads. Please try it first.
