Free open source app that lets you view and search reference materials such as Wikipedia, Gutenberg, StackExchange etc without an internet connection. This can be very useful in remote areas, during temporary outages, or during times of turmoil. Kiwix is available for Linux, Mac, Windows, Android and iPhone/iPad. You can optionally also create a self-hosted Kiwix hotspot, so that anyone physically near your server can access your copy of Kiwix through a local connection.
