GitHub - plainhub/plain-app: 🔥 PlainApp is an open-source app that lets you securely manage your phone from a web browser.

PlainApp

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. Supports PWA so you can pin it to your desktop like a native app.

• RSS Reader — follow your favorite websites with a distraction-free reader

• Video & Audio Player — full-featured media player with playlist support

• Pomodoro Timer — stay focused with a built-in work timer

• Sound Meter — measure ambient noise levels in real time

🔒 Privacy & Security

• Zero data sent to any third-party server

• All traffic between phone and browser is encrypted (TLS + XChaCha20-Poly1305)

• No account registration required
