## What is Rendr Markdown?

Rendr shows Markdown documents as native previews on iPhone and iPad. It opens files from Files, iCloud Drive, and other apps in place, without importing or changing them.

What Rendr renders:

- GitHub-flavored Markdown, including tables, task lists, footnotes, alerts, autolinks, and heading anchors.
- Syntax highlighting for fenced code.
- Mermaid diagrams, a supported subset of PlantUML, and KaTeX math, all rendered offline.

What you can do:

- Use the heading outline, find, zoom, and document information.
- Share or export as PDF or as HTML without scripts, and print.
- Choose GitHub, Reader, Developer, or one of five Token themes, in light, dark, or system appearance.
- Grant and revoke folder access for local images and media.
- Open multiple windows on iPad.

Privacy

Rendr has no account, analytics, telemetry, document uploads, or remote rendering service. Remote images and media are blocked whenever a document opens. You can load them for that document until you close it. Loading them contacts the server that hosts them and may disclose your IP address. Standalone HTML never loads remote content.

One purchase covers Rendr on Mac, iPhone, and iPad.

Requires iOS 26 or iPadOS 26 or later.

## Version history (last 5 releases)

### 3.6.6 — 2026-11-08

Rendr draws tables more cleanly on Mac, iPhone and iPad.

- Tables no longer end with an empty row inside their border.

### 3.6.5 — 2026-11-07

Rendr now draws diagrams with Mermaid 12.3.0.

- Flowcharts can show the order of their steps. Give an arrow an ID and a step number, as in `A e1@--> B` and `e1@{ step: 1 }`, and a dot moves along the arrows in that order. The dot stays hidden when Reduce Motion is on.
- Swimlane diagrams size nested groups correctly and no longer draw an empty lane when a box is listed in two lanes.
- Mermaid's built-in cleaner, DOMPurify, is updated to 3.4.17 with two security fixes.

### 3.6.4 — 2026-10-30

Rendr now draws math with KaTeX 0.19.1.

- KaTeX 0.19.1 fixes a parser bug with percent signs in command arguments that it reads as plain text.

### 3.6.3 — 2026-10-23

Links from the App Store can now open Rendr on iPhone and iPad.

- A `rendr://` link opens Rendr on iPhone and iPad and keeps the current document open.

### 3.6.2 — 2026-10-23

No release notes.
