Download the Ondol Life planner

Desktop app, version 0.1.1. It opens the planner in its own window; the content always matches the website.

First open on a Mac: if macOS says it cannot verify the developer, go to System Settings → Privacy & Security and choose Open Anyway.

First run on Windows: if SmartScreen appears, choose More info → Run anyway.

Or use it in your browser, no download: Open the web app
