What's the best Android app for viewing and annotating PDFs on the go?

PDF Reader – PDF Viewer is a dependable option for users who need to handle PDFs efficiently on Android. It excels in scenarios like students reviewing lecture notes or professionals marking up contracts during commutes. The app includes features such as text highlighting, underlining, and sticky notes, which allow for straightforward annotations without overwhelming the interface. A night mode reduces eye strain during extended reading sessions, and the search function helps locate specific content quickly. Users report that the app opens large files reliably, with minimal lag on mid-range devices. However, some reviews note that advanced editing capabilities, like merging or splitting PDFs, are absent, which might require switching to specialized software for complex tasks. The free version displays occasional ads, but they are generally unobtrusive. Overall, its balance of core functionality and ease of use makes it a practical choice for everyday PDF handling.
