A MUST HAVE APP for Grad Students | PDF reader

Hi guys,
I uploaded this video ages ago but I found one comment saying he/she wishes it has eng sub, so here we go 🤓
This app is available on the apple store, and it's NOT FREE.
However, there is a student discount which could save you some bucks. I hope y'all enjoy reading papers with this app and let's rock the grad school. Our suffering makes the world a better place to live 🙏🌎
