This is the donate version of Lucid Browser and contains no ads which allows for a smaller app size.
Lucid Browser is a small, light, fast, and simple web browser allowing you to surf the web with speed. The Donate version of the app is only about 2 MB. The browser uses a custom homepage that loads locally for quick start-ups. Although it is small in size, it packs a punch with all the features you would normally see in a mobile browser. For example, you can import bookmarks from other browsers that use file formats of HTML or JSON. By default, Lucid Browser uses Ecosia, a project designed to help plant trees. The browser also allows for complete management of bookmarks with folder categorization. Lucid Browser also comes with many settings and ways to personalize the look. It is easy to use and very handy.
