Check out the example provided in Unity's API on Input.getTouch
https://docs.unity3d.com/ScriptReference/Input.GetTouch.html
There is a Touch struct that handles device screen touches.
Input.touchCount -> Returns the number of 'touches' on the screen (finger or stylus).
Then, Input.getTouch, gives us that Touch struct.
The Touch struct has attributes like the position, angle, action (is it moving?) Etc.. on the screen.
