About Plain App

PlainApp is an open-source Android app that hosts a local dashboard for managing the phone from a desktop web browser. From the browser users can browse files on internal storage, SD card and USB drives, view and stream photos, video and audio, manage contacts, read messages and call logs, send SMS, list apps and export APKs, view notifications, mirror the screen, and check battery, storage and network details.

The phone and computer must be on the same Wi-Fi network, with no installation required on the computer aside from the browser. The project describes browser-to-phone traffic as encrypted with TLS and XChaCha20-Poly1305 and states that no account registration is required.
