"OxygenGuide is Wikivoyage in the form of simple HTML files. No images.
Must-have on your smartphone or travel laptop. Whole world in 90MB.
I created an Android app but haven't much time to maintain/improve it, I
am looking for a new maintainer, anyone interested? It can be a fun
project for someone who is starting to learn Android development, so
don't hesitate :-)
Some help would also be welcome to enhance the algorithm which
transforms Wikivoyage wikicode into simple HTML."
