What is Appllama?
Appllama is a curated library of UI/UX screenshots from high-revenue iOS apps, serving as a reference tool for mobile product designers, product managers, and indie developers. It offers searchable flows, screens, and UI elements, with contextual revenue data to identify what works commercially. The product monetizes via a freemium model with a Pro subscription, providing design inspiration to teams at companies like Duolingo, ChatGPT, and AllTrails. Its moat is the proprietary combination of high-signal curation (top-earning apps) and revenue data, which sets it apart from generic screenshot galleries.
