Why SimplyInk

A notebook that keeps up with your hand.

Pens, paper, stationery and PDF pages in one place — plus tools that let you change ink after you write, not only while the stroke is wet.

A real PencilKit canvas

Ballpoint, fineliner, brush, graphite, fountain pen and highlighter — each with its own colours and widths. Pressure-sensitive strokes, Apple Pencil hover, and draw-and-hold to snap freehand into clean shapes.

Change ink after you write

Brush the Color Changer over strokes, shapes or text to recolor them — or limit it to one source colour. Brush the Width Changer to thicken, thin or set a width. Either tool can run on a whole page.

PageApply once, undo once

Desk Kit stationery

Washi and study tape, sticky notes, stamps, index flags, reveal tape and more — place or drag them onto the page like real desk supplies.

PDF annotation

Import a PDF as a notebook, mark it up with ink and text, then export the whole book or selected pages.

iCloud sync

Start a page on iPhone, finish it on iPad. Notebooks sync through your private CloudKit container.

Find what you wrote

On-device handwriting recognition indexes every page. Search from the library or the editor, jump to the match, and see it highlighted on the page — typed text and imported PDF text included.

The Changers

Brush over ink. Fix it in place.

Most note apps lock colour and width the moment the stroke lands. SimplyInk lets you revise ink the way you’d revise a sketch — with a brush.

01

Color Changer

Pick a colour, brush over ink or shapes. Limit to one source colour, or recolor a whole page — even every page in the notebook.

02

Width Changer

Choose Thicker, Thinner or Set a width, then brush over strokes. Apply to the whole page when you want one pass.

03

Lasso & Convert

Select handwriting, move and resize it, or Convert to Text with on-device recognition — one undo brings the ink back.

FAQ

Questions people ask before downloading

Is SimplyInk a subscription?

No. There is no subscription. You can download SimplyInk and try every tool with limited notebooks — 1 notebook (up to 3 pages) and 1 PDF-import notebook (the PDF’s own pages plus 3 more). SimplyInk Pro is a one-time purchase that removes those notebook and page limits for good.

How do the Color and Width Changers work?

Select the tool, pick a colour or width mode, then brush over existing ink or shapes. You can limit the Color Changer to one source colour, and apply either tool to a whole page.

Can I annotate PDFs?

Import a PDF as a notebook, write on it with ink, shapes and text, then export the notebook or selected pages as a PDF from Share.

Does it sync between iPhone and iPad?

Yes, through your private iCloud account (CloudKit). Turn sync off anytime to keep notebooks on one device.

Do I need an account?

No sign-up. Notebooks live on your device and, if you enable iCloud, in your own iCloud container.

What else is included?

Zoom Box, Desk Kit stationery, guides and shapes, rich text, images, audio notes synced to ink playback, handwriting search, Color Key & Lens, locked notebooks, widgets and Share → SimplyInk.
