Skryn

A lightweight macOS menu bar app for taking screenshots and annotating them.

Installation

1. Download Skryn.zip from the latest release
2. Unzip and drag Skryn.app to your Applications folder
3. Open the app. macOS blocks the first launch because Skryn isn't notarized by Apple: go to System Settings → Privacy & Security and click Open Anyway (on macOS 14, right-click the app → Open also works)
4. Grant Screen Recording permission when prompted

Updating

Since v0.1.6, Skryn is signed with a stable certificate, so Screen Recording permission carries over when you update.

Updating from v0.1.5 or earlier needs a one-time reset, because the signature changed. If screenshots stop working:

1. Go to System Settings → Privacy & Security → Screen Recording
2. Remove Skryn from the list
3. Take a screenshot; Skryn will ask for permission again

Usage

Click the camera icon in the menu bar or press Cmd+Shift+5 (configurable in Settings) to capture your screen. An annotation window opens where you can draw before saving. You can also drag an image file onto the menu bar icon to open it for annotation.

Shortcuts

• Drag — Arrow
• Shift + Drag — Line
• Cmd + Drag — Rectangle
• Option + Drag — Crop
• Control + Drag — Blur

You can also hover over the annotation and change its size or drag it.
