This page lists all published Logo apps. Click on any word of the tag cloud to the right to only list apps that match the clicked tag. You can also search the table for specific words; the table adjusts to what you type. Click the app name in the table to launch the app.
You can download many apps as a Zip file archive, which you then can upload into your copy of Logo, or you can extract the contents and work with the files inside the archive. The "Count" field in the table below displays how often an app has been accessed.
Your own apps display two additional icons. The icon loads your app into Logo so you can edit and re-publish it, and the icon deletes your app.
