Work, personal life, and everything between deserve their own Space. Crest is a native browser for iPhone and iPad that keeps your accounts separate, your tabs organized, and your browsing distinctly yours. KEEP YOUR ACCOUNTS SEPARATE Each Space has its own tabs, cookies, website data, history, passwords, and site permissions. Stay signed in to different accounts on the same website. Switch from work to personal browsing without carrying the wrong session with you. GIVE EVERY TAB A PLACE Pin the sites you use every day. Save pages in folders. Keep today's tabs close and completed work in the archive. Select and move tabs, folders, and Split View groups together. On iPhone, bring in the sidebar with a gesture; on iPad, keep it beside your page. MAKE IT YOUR OWN Start with a Winter, Lion, or other crest template in Crest Studio, then change the colors, artwork, and background. Choose a crest, emoji, monogram, or symbol. Look and Feel lets you adjust the sidebar's edge, tab appearance, borders, icon colors, and default page zoom, with a live preview. KEEP RELATED PAGES TOGETHER Group two to four pages in Split View. On iPad, browse them side by side and resize the columns. On iPhone, swipe across the compact toolbar to move between pages in the group. Peek lets you check supported links without losing your place, then keep the page as a tab when you need it. TOOLS FOR EVERYDAY BROWSING Translate webpages on device with Apple's Translation framework. Read supported articles in Reader, find text on a page, adjust zoom, share links, and export pages. Content blocking and site permissions give you control over each Space. Language availability varies, and translation may require a language download. PRIVATE WHEN YOU NEED IT Private Browsing uses temporary website storage. Private tabs stay out of saved history, restoration, archive, and sync. Crest does not run an advertising SDK, collect browsing analytics, or require a Crest account. PICK UP ON ANOTHER DEVICE Optional iCloud sync keeps supported Space and tab organization available across your Apple devices through your private iCloud database. Crest is also available for Mac. Crest is free and open source, built with Apple's WebKit. Requires iOS 26.1 or iPadOS 26.1 or later. Some website features and integrations vary by device.
