Stash - Save & Organize Links

Stash is a mobile application designed to help users save, organize, and revisit their favorite web links. It aims to reduce distractions from social media by providing a centralized 'Read Later' hub. The app offers effortless bookmarking, smart organization features, and a visually appealing browsing experience.

Stash is an iOS app that allows users to save and organize links, which directly aligns with the core functionality of URList. It emphasizes effortless bookmarking and smart organization, and the ability to share links. While it doesn't explicitly mention 'contextual side notes' or 'Tufte-style' notes, its primary function of saving and organizing links for later consumption is a strong match. The app is also mobile-responsive as it's an iOS app.
