The official Wikipedia Android app is designed to help you find, discover, and explore knowledge on Wikipedia. Settle a bet with a friend by doing a quick search through the app, or dive into featured articles, images, recommended articles, and more using the Explore feed. With more than 39 million articles in nearly 300 languages, your favorite free online encyclopedia is now at your fingertips.
Explore feed: Recommended and constantly-updating Wikipedia content right on the home screen, including current events, trending articles, events on this day in history, suggested reading, and more. The feed is fully customizable — you can select the types of content you want to see, or rearrange the order in which different types of content appear.
Color themes: With a choice of Light, Dark, and Black themes, as well as text size adjustment, you can customize the app for the most comfortable reading experience.
Voice-integrated search: Easily find what you’re looking for with a prominent search bar at the top of the app, including voice-enabled search on your device.
Nearby: Learn more about what’s around you by selecting points on an interactive map to see articles related to your current and nearby location.
Language support: Seamlessly switch to reading any language-supported Wikipedia, either by changing the language of the current article, or changing your preferred search language while searching.
Link previews: Tap on an article to preview it, without losing your place in what you’re currently reading. Press and hold a link to open it in a new tab, allowing you to keep reading the current article without losing your place, and switch to the new tab when you’re ready.
Table of contents: swipe left on any article to bring up the table of contents, which lets you jump to article sections easily.
Reading lists: Organize the articles you browse into reading lists, which you can access even when you’re offline. Create as many lists as you like, give them custom names and descriptions, and populate them with articles from any language wiki.
Image gallery: Tap on an image to view the image full-screen in high resolution, with options to swipe for browsing additional images.
