PlainApp: Phone Web Portal — Open Source Productivity App

**PlainApp** is a free, open-source Android app that turns your phone into a self-hosted management hub you can access from any web browser on the same network — no accounts, no cloud, no subscriptions. Whether you need to transfer files, read SMS, browse photos, or mirror your screen, PlainApp puts full control back in your hands. ## Why PlainApp? Most phone-management tools either route your data through their own servers, lock features behind subscriptions, or plague you with ads. PlainApp is different: - **100% local** — your data never leaves your network - **End-to-end encrypted** — every connection is secured with TLS + XChaCha20-Poly1305 - **Completely free and ad-free** — no purchases, no upsells, ever - **Fully open-source** — audit the code, build your own binary, or contribute ## Features ### 🌐 Web-Based Phone Management Open a browser on any desktop or laptop connected to the same Wi-Fi network and get a full dashboard to manage your Android device — no app installation required on the computer side.
