I couldn’t believe the app is FREE – PDF Viewer - Annotation Expert Review

The app super well organized and the new update just takes it to the next level. I am a graduate student and have tons of papers and lectures to read and usually have all of them organized in a pen drive for quick access across all platforms. Initially after iPadOS update, I was upset that we can’t directly open files from external sources but the new update is amazing. Thanks a lot developers. This is ‘the’ best PDF reader for iPads and iPhones right now.
