Mobile-First Personal & Shared Secure File/Media Server Platform

The user has a successful paid Android app ('Wifi Server Pro') for local file sharing but is struggling with growth and monetization. Comments suggest evolving it into a more comprehensive, mobile-first personal and shared file/media server platform. The core problem is the need for flexible, secure, and user-friendly ways to access and manage files/media from mobile devices, beyond basic local sharing. A SaaS opportunity exists to expand the existing app into a powerful system that offers not just local Wi-Fi serving, but also secure remote access (via VPN integration or custom tunneling), advanced file management features (e.g., media streaming, folder sync, versioning), direct share link generation, and multi-user/permission management. This would cater to individuals seeking an easy-to-use personal cloud solution, families sharing media, or small businesses needing simple mobile-centric file access. The product would be a mobile app with a web UI component, monetized through a freemium model: basic local features are free, while remote access, advanced management, and multi-user capabilities are tiered subscriptions.
