**Browsing that's easy on your eyes.** Sloths Browser is a fast, uncluttered web browser built around one idea: the web should be comfortable to read, at any hour. **Night Mode that follows the sun** A warm tint slides over everything after dark and lifts at sunrise. It can follow your local sunset and sunrise times, or run on a schedule you set yourself. Adjust the warmth to taste. **Private really means private** Private tabs use separate, in-memory storage. Nothing is written to your history, and cookies are discarded the moment you close the tab. Not hidden — gone. **Secure by default** Type a web address and it's upgraded to HTTPS automatically. A padlock shows when a page is genuinely encrypted, and a warning shows when it isn't. **A start page worth opening** Your favourites and recent sites are one tap away, instead of a blank box. **Downloads that stay put** Touch and hold any link to download it. Files are kept on your device where you can preview, share or delete them. **Route through your own proxy** Point the browser at a proxy server you trust and every page loads through it, private tabs included. Your proxy, your rules. **Made to stay out of the way** Full support for Dark Mode, Dynamic Type and VoiceOver. Works properly on iPad, in landscape, and in Split View. Keyboard shortcuts when you have a keyboard attached. **Remove ads with Sloth Pro** Sloths Browser is free and supported by occasional ads. Sloth Pro is a yearly subscription that removes them, and it restores to your other devices. Already bought the old one-time upgrade? It still counts. Sloth Pro is yours permanently, with nothing to renew and nothing to pay — thank you for backing the app early. https://sites.google.com/view/mobtech-studio/privacy-policy https://sites.google.com/view/mobtech-studio/terms
