Do you maintain a physical book for your to-day lists or are you keeping them digitally?

I use a physical book, so that it’s feels more important and separate from the fabulous which could do the same thing if I wanted it to.

Physical book, because the things I need to do are physical, and I don't want all the distractions that come with checking it on my phone!
It also means I can do rewarding things like crossing out and ripping out pages whom I'm done!
