Getting Started
If you have just downloaded Krux, here is what to know:
- Open the app. There is no account to create, no onboarding flow, and no permissions to grant. You are in the editor immediately.
- Create or open a file. Tap the new document button to create a
.mdfile, or open an existing markdown file from Files or iCloud Drive. - Use the outline. Tap the outline icon in the toolbar to see all headings in your document. Tap any heading to jump directly to it.
- Sync with iCloud Drive. Your files sync automatically. Open the same file on your iPhone, iPad, or Mac. No setup required.
- Try your Apple Watch. Open the Krux companion app on your Watch. Dictate a note or browse your recent files.
Frequently Asked Questions
How do I back up my files?
Your Krux files are standard .md files in iCloud Drive. Apple backs up your iCloud Drive automatically as part of your Apple ID. You can also manually copy your files to any other location using the Files app on iPhone or Finder on Mac. Since Krux uses plain markdown files — not a proprietary database — you can back them up the same way you back up any other file.
Can I import files from other markdown editors?
If your files are already in .md format, you can open them in Krux directly — just place them in iCloud Drive or open them from the Files app. If your files are in a proprietary format (such as encrypted notes or proprietary document formats), you will need to export them as markdown from those apps first. Most markdown editors include an export-to-markdown option.
Why does Krux require iOS 26?
Krux is built natively for iOS 26 using Apple's latest Liquid Glass design language, Swift 6.2, and the newest SwiftUI frameworks. Requiring iOS 26 means Krux can use the most current Apple APIs and deliver a modern experience that matches the rest of your device. Older iOS versions are not supported.
How do I use the Apple Watch app?
The Krux Watch app installs automatically when you install Krux on your iPhone (if your Apple Watch is paired). Open the app on your Watch to browse recent documents, read notes offline, or dictate a new note. You can also add the Krux complication to your watch face for one-tap note capture. Dictated notes sync back to your iPhone automatically.
How do I export to PDF?
Open the document you want to export in Krux. Tap the share icon in the toolbar and select your format: HTML, PDF, or Markdown. For PDF export, Krux generates a cleanly formatted document. The exported file appears in the standard iOS share sheet, where you can save it, send it, or open it in another app.
I found a bug. How do I report it?
Email support@krux-md.com with a description of what happened, what you expected to happen, and which device and iOS version you are using. Screenshots are helpful. We read every email.
Does Krux support tables and code blocks?
Yes. Krux renders GitHub Flavored Markdown (GFM), which includes tables, fenced code blocks, task lists, and strikethrough text. What you write in Krux will render correctly in GitHub, GitLab, and any other GFM-compatible tool.
Will Krux work without an internet connection?
Yes. Krux works fully offline. Your files are stored locally on your device. iCloud Drive sync happens automatically when you reconnect. The Apple Watch app also works offline — dictated notes sync back when your devices reconnect.
