About Solipsism Browser
Solipsism Browser is a rail-first Android WebView browser designed around one-handed browsing. Navigation, tabs, search, QR scanning, refresh, and the overflow menu live in a compact side rail that can be placed on the left or right. The browser focuses on mobile ergonomics, privacy-aware controls, and a tactile Material Design 3 Expressive-inspired interface.
