It is an offline world travel guide. Wikitravel is a great website to gather information about places. But there might be situations when people are not able to access the Internet so OxygenGuide may be useful for them.
Currently OxygenGuide make use of the OxygenPump dumps downloaded from the Wikitravel website.
There are several features that this guide can include in future. We are trying to extend its scope further to include more and more features in future.
