Link Cluster

Link Cluster is a productivity app for Apple devices that allows users to collect, organize, and manage web links. It features link clustering, automatic link enrichment with previews, personal notes, and seamless synchronization across devices via iCloud. The app aims to help users keep track of online content like articles, recipes, and tutorials.

Link Cluster is a strong match for the URList concept, offering core functionalities like saving and organizing links into 'clusters' (lists/sections) and adding notes. It also provides automatic link enrichment with images and descriptions, which aligns with the 'URL Saving & Preview' feature. The app supports easy link addition and is available across multiple Apple devices, indicating mobile responsiveness. While it doesn't explicitly mention public sharing without sign-up, it does allow sharing with friends and exporting, which is a partial match. The primary difference is its focus on a personal collection rather than public curation.
