InkLayer

Handwriting, PDFs & Markdown

Free · In-App Purchases

Handwrite on PDFs and notes on one canvas. Free for 3 handwritten documents; InkLayer Lifetime is one purchase, with every future on-device update included. InkLayer is a notebook for reading, research and handwritten thinking. Handwriting, PDFs and Markdown notes share one canvas, and everything is saved as files you own. Write notes as real Markdown files. Open PDFs without modifying the original document. Draw with pens, highlighters, shapes and erasers on top of notes or PDF pages. Show, lock, reorder and fade layers so sources, handwritten derivations and your summaries stay separate. Core features: - A library of real Markdown files, kept on your device. - Handwriting and highlights on PDFs, with the original file untouched. - Shape recognition, a precision eraser, a full lasso (move, resize, rotate, recolor, copy and paste) and a laser pointer. - Layers with visibility, lock, opacity and order. - Markdown preview with math, wikilinks, tags, backlinks and a graph view. - Search across your library, including handwriting recognized on the device. - Sync through your own WebDAV server; conflicts keep both versions. - Present a PDF or a canvas full screen with your handwriting on it: a laser pointer, a pen for writing on the slides, and pages turned from the keyboard or a presentation remote. - Open PDFs and Markdown files in InkLayer straight from Files, Mail, Safari and other apps. - E-ink mode: grayscale, high contrast, no animation. - Export and import your whole library without an account. Free to download, with every feature: handwrite in 3 documents for free. InkLayer Lifetime is one purchase that removes the limit, and every future on-device feature update is included. Nothing you write is ever locked. No account is required, there is no AI, tracking or ads, and your library stays portable.
