Inkstone is a Markdown writing app for iPhone. Your notes are ordinary .md files, in a folder you can open from anywhere.
If something here does not answer your question, see Getting in touch at the bottom.
They are real files, and you can always find them outside the app.
The switch is in Settings inside the app. Turning it on copies your notes into iCloud Drive; turning it off leaves the iCloud copy where it is rather than deleting it, so nothing vanishes by accident.
A note I edited on my Mac has not appeared.
iCloud syncs in its own time and needs both devices online. Leave the app open for a moment, or pull down on the note list. If a note was changed in two places at once, Inkstone keeps both rather than picking a winner: the second version is saved beside the first, with the time of the change in its name.
Can I use my existing folder of Markdown files?
Yes — copy them into the Inkstone folder in the Files app. They are read as they are; there is no import step and no database.
How do I link one note to another?
Type [[ and the note's title. If no note has that title yet, tapping the link creates it. The Links button lists the notes that point back at the one you are reading, and renaming a note updates every link to it.
The Markdown preview does not show my diagram or formula.
Diagrams need a fenced block marked mermaid; formulas use $…$ inline or $$…$$ on their own lines. Both render offline — nothing is fetched from a server — so a syntax error in the block is the usual cause. An unrenderable diagram falls back to showing the code, which is a hint about where to look.
How do I paste a formatted note into another app?
The third button in the bottom bar, Copy Styled, copies the note as rich text with the typesetting applied, which is what publishing composers paste. The button beside it copies the raw Markdown instead.
How do I get a note out as a PDF?
Open the note, tap the ⋯ button in the top right, and choose Export as PDF — or Export as HTML. Images are carried inside the exported document.
Does Inkstone send my notes anywhere?
No. There is no account, no analytics, and no server. With iCloud sync on, your notes are in your own iCloud account and nowhere else. See the privacy policy.
The most useful report says what you did, what happened, and what you expected instead. If it involves a specific note, the Markdown that triggers it helps more than a screenshot — but please remove anything private first.

Open an issue on GitHub Issues. Bug reports and questions both belong there.
