Developer: BruceDevices · License: AGPL-3.0 (open source) · Price: Free
Before you start: you need a Bruce Firmware device. To use Screen Mirror, enable WebUI on the device and connect to Bruce's WiFi access point, then enter bruce.local or the device IP in the Screen Mirror panel and press Start Mirror. For desktop firmware flashing, you also need JDK 21+ and Python 3 with esptool installed (pip install esptool).

Why isn’t Bruce App on Google Play?
It is published by its developers on GitHub rather than on Google Play. It is not listed on F-Droid either.
Is Bruce App safe?
This is open-source software released under the AGPL-3.0 license, built from the BruceDevices/App repository. The Android APK is built from source (debug or release build via Gradle), so there is no separate signed file listed in the README; check the GitHub releases page for the official v1.3 build. Bruce App comes straight from its developer rather than through Google Play, so it hasn’t gone through Google’s app review. As with any app, check the permissions it asks for and install it if you’re comfortable with them.
How to install
- Tap the download button above: the APK file downloads straight to your phone.
- When Android asks, allow your browser to install unknown apps.
- Open the file and tap Install.
