xnotes

xnotes is a handwriting-first notebook for phones and tablets, built for pen and stylus. Write, sketch and annotate naturally, with a simple interface that stays out of your way.

Import PDFs and write directly on them, perfect for notes, worksheets, documents, textbooks and anything else you want to mark up.

Need more room? Use the infinite canvas to keep writing, drawing and exploring ideas without being limited by page boundaries.

Make every notebook your own with endless themes and customisation options. Change the look and feel of your pages to match your style, workflow or mood.

Reading at night is easier too. Invert PDFs, apply a sepia filter, or change PDF font colors for better visibility in low light. xnotes also includes dedicated dark and OLED modes for night owls who prefer a darker workspace.

xnotes is completely free and open source. No locked essential features, no proprietary format holding your notes hostage, just a flexible notebook built for people who want a better place to think, write and create.
