Elnefolio is a PDF and note app for Android. Import a PDF, write with pen and highlighter, add shapes, text and images, and hide things you want to memorize behind masking tape, then tap to reveal. Notebook templates (blank, lined, grid, dot, Cornell) and a planner are included. Documents stay on your device and core editing works offline, with no ads and no usage tracking. Export to PDF with your notes, PNG pages or a backup file.
