Paul Le Gall is an independent developer who maintains a small, focused portfolio of lightweight browser-based utilities under the GitHub handle “luapp.” The collection centers on single-purpose WebApps that distill everyday tasks into minimalist interfaces: a Covid-19 tracker that visualizes daily new-case trends from public data feeds, and a no-frills To-Do list that lets users jot down and tick off tasks without leaving the page. Both tools are built with vanilla HTML, CSS and JavaScript, so they load instantly on any modern browser, require no installation, and store data locally to respect privacy. Typical use cases include quick situational checks—journalists verifying outbreak numbers, travelers assessing regional risk, students managing assignment lists, or office workers keeping a transient scratchpad during calls. Because the code is open-source, technically inclined visitors can fork, skin or extend the apps for intranet dashboards, classroom kiosks or community bulletin boards. Despite their simplicity, the projects demonstrate responsive design, offline caching and clean REST consumption, making them suitable for embedding in larger portals or running as portable bookmarks across Windows tablets, laptops and shared PCs. The publisher’s software is available free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always pulling the latest versions and supporting batch installation of multiple applications.
