PDF4Teachers is a free open-source app specifically designed for teachers to annotate assessments returned in PDF with high productivity. As of V1.1.0, PDF4Teachers is now fully translated into English, making it even more accessible.
PDF4Teachers offers a range of tools for productive PDF editing, including annotation and correction of assessments. What's more, edits are saved separately from PDF files and saved annotations can be quickly inserted for future use. Documents are managed as a set and can be exported as new PDF files with annotations.
