Read full description

Stop searching for the same web pages over and over. TabTasu is a browser that keeps related tabs together in purpose-based groups, so the pages you use often are always easy to find. Organize pages for job searches, investing, fandoms, gaming, study, or any topic you revisit. Switch groups whenever your focus changes and pick up where you left off. PERFECT FOR • People who revisit the same pages every day • Research that requires moving between multiple websites • Keeping work, hobbies, and study pages separate • Anyone tired of digging through an endless list of tabs • Browsing in public when you would rather keep the current screen hidden KEY FEATURES • Organize multiple tabs into purpose-based groups • Keep the current page and tab order ready for later • Switch groups and return to your usual pages quickly • Set a custom name and home page for each tab • Add, reorder, and protect important tabs • Browse history separately for each group • Long-press a link to open it in a new tab • Share pages, go back or forward, and reload • Cover Mode hides browsing content when the app opens, groups switch, or the app returns from the background • Private Mode avoids saving in-app browsing history and uses non-persistent website data Works on iPhone and iPad in portrait and landscape, with support for Light and Dark Mode. Spend less time rebuilding your tab setup and more time on what you came to do.
