Most beautiful and convenient pdf reader

Good interface, store web document in phone or connected one-drive, marker the document and highlight important part very easily. Zoom in or zoom out is very powerful.

Works great for textbooks

This app is great for navigating and annotating textbooks. The scroll bar is a little hard to grab, and it was a little tricky to figure out how to load the PDFs on using iTunes, but these are very minor issues.

Muito bom!

Assim como outros apps da Readdle, este é o melhor da categoria.

Excellent app

Does what it should do exactly

Easy to use

I find this app easy to use when it comes to marking up PDFs and managing files. Easy to create folders for file management and move files around to different folders. I have received compliments on the quality resolution of my signature saved in the app.

I use this app ALL the time

Great app


Works well, recommend! Useful app
