Work Oasis by Tristan Locke

Work Oasis helps pages feel quiet and focused so you can stay with the task at hand. Turn it on globally or just for the current site and common distractions such as sidebars, share bars, comments, overlays, popups, and sticky widgets step out of the way so content is easier to read. You control how strong the cleanup should be with a simple strength slider. If bright screens tire your eyes, add a soft dim to lower visual intensity. For extra comfort, enable the reading setting to increase line height and slightly enlarge body text. When a page needs special care, you can add your own CSS selectors and those elements will be hidden as well. Preferences are stored locally, there are no accounts to create, and no data leaves your device.
