Hiyd
Hiyd is built around one job: getting a well-formed Markdown post out of your head and into your Jekyll repository with as little friction as possible. This guide covers your first post from install to export.
1. Install
Download Hiyd from the App Store. It runs on iPhone and iPad and needs iOS or iPadOS 18.6 or later. There is no account to create and nothing to configure before you start writing.
2. Write a post
Open the Create tab. You get two fields:
- Item Title — becomes the
title:in your front matter. - Item Body — your post content in Markdown.
Write as you normally would. Headings, lists, links, code fences and images all pass straight through untouched.
3. Check the front matter
Tap the preview (eye) button in the toolbar to see the finished file. Hiyd always includes:
---
title: Your title
date: 2026-09-10 09:24:00 +0100
---
If you have configured default front matter fields —
author, tags, categories, a draft flag and so on — they appear here too,
pre-filled with your defaults.
4. Save, export or publish
From the More actions (•••) menu you can:
| Action | What it does |
|---|---|
| Save | Writes the .md file into iCloud Drive › Hiyd, where it syncs to your other devices and shows up in the Archive tab. |
| Export | Opens the share sheet so you can send the file to another app, AirDrop it to a Mac, or save it elsewhere in Files. |
| Publish | Commits the file to a GitHub repository you have configured. |
5. Find it again
The Archive tab lists every saved file with search. Swipe a file to delete it, or open it to restore it into the editor for another pass. Because the files are plain Markdown in iCloud Drive, you can also open the same folder on a Mac at iCloud Drive › Hiyd.
Where the file goes on your site
A Hiyd post is a standard Jekyll post: a YAML front matter block followed by
Markdown. Drop it into your _posts folder (or publish straight there) using the
Jekyll naming convention YYYY-MM-DD-title.md and your site build will pick it
up. Hiyd names saved files this way automatically.
