What application have you recently discovered?

Yes… it is expensive unfortunately. I dont mind they take out the stylus and the sleeve and make it half price. But it is the screen size I am after.
Yesterday I saw a Lenovo 2 in 1 laptop that has 2 screens, the normal one and the outside one is eink.
Still need to study it further.
UPDATE:
I found it in my history
