As answered by people managing AppWrite and Pool-Buddy.de.
Pool-Buddy.de's answer:
Pool Buddy is currently focused on individual pool owners and does not have any major publicly disclosed customers yet.
Pool-Buddy.de's answer:
Pool Buddy combines water analysis, chemical dosing, guided diagnostics and long-term trend tracking in one privacy-friendly Progressive Web App. Instead of only displaying target ranges or calculator results, it explains what the values mean and gives users clear next steps. It also includes advanced tools such as OCLT support, CSI evaluation and intelligent trend analysis, while remaining approachable for beginners.
Pool-Buddy.de's answer:
Pool Buddy is designed to turn pool-water data into practical guidance rather than just numbers. It combines dosing calculations, diagnostics, measurement history and trend analysis in a single app, works without requiring an account and offers offline functionality. The interface is built to be easy for beginners while still providing advanced tools for experienced pool owners.
Pool-Buddy.de's answer:
Pool Buddy is primarily built for private swimming-pool owners who want an easier way to understand and maintain their water chemistry. It is especially useful for beginners who need clear guidance, but it also provides advanced diagnostics, history and analysis tools for experienced pool owners.
Pool-Buddy.de's answer:
Pool Buddy was created to solve a common problem in private pool care: owners are often confronted with measurements, chemical products and conflicting advice without knowing what they should actually do next. The goal was to build a tool that turns water-test results into understandable explanations, accurate dosing guidance and practical next steps, all in one easy-to-use web app.
Pool-Buddy.de's answer:
Pool Buddy is built as a Progressive Web App using HTML5, CSS3 and JavaScript. It uses JSON-based data and configuration, a Web App Manifest and Service Worker technology to provide an installable, app-like experience with offline capabilities across modern browsers and devices.
