Anyone who relies on Safari extensions, synced bookmarks or open tabs that survive a restart should stay with Safari, since tabs last only for the current session.
Widezilla is a native browser for the iPhone Duo. A floating glass address bar sits at the top beside the system indicators or at the bottom, and pages keep their reading position when you fold or unfold. Save favourites with site icons, switch with visual tab cards and get suggestions from favourites, tabs and recent visits. Choose Google, DuckDuckGo, Bing, Ecosia, Kagi or a custom search. EasyList and EasyPrivacy blocking cuts many ads and trackers, and an optional adaptive dark mode darkens websites. It needs iOS 27.1 or later.
Its App Store description says it is built specifically for the iPhone Duo, with independent status bar settings for the outer display, inner display and Split View; version 2026.11.7 (4 November) also improved layouts on the outer display. Its maker's site shows the open Duo with a Wikipedia article on the red panda running the full width under the floating address bar.
