Bisbi: a privacy-focused Android app designed to alert you when someone might be looking at your phone screen. It uses the front-facing camera for on-device face detection and features a floating indicator that changes color based on detected activity. Bisbi can run in the background, send optional vibration or sound alerts, and offers adjustable settings for sensitivity and display. Premium features include capturing an image of the intruder and automatically dimming the screen brightness.
SMART SCREEN PRIVACY DETECTION
Bisbi uses the front-facing camera to monitor the area around your phone and identify when another person appears near the screen. A floating indicator provides a quick visual status, changing color between green, orange, and red depending on what the camera detects. Adjustable sensitivity settings help adapt the app to various environments, while a dedicated check screen allows you to see how the detection works.

BACKGROUND ALERTS AND CONTROLS
The app can continue monitoring while you use other applications, providing notifications when relevant activity is detected. Optional vibration and sound alerts offer additional warnings, and the floating indicator can be moved to your preferred position on the screen. Users can also customize its size, colors, and overall appearance via the available settings.

ON-DEVICE PRIVACY FEATURES
Bisbi is designed for local processing, analyzing camera frames directly on the device instead of sending images to a remote server. The app requires no account or prior facial registration, and the developer states that images captured by the camera are processed within the device’s memory. Premium options add an intruder capture feature—which locally stores an alert image—as well as automatic screen dimming when someone is detected looking at the display.
- Processes face detection directly on the device.
- Uses the intruder capture feature to locally save an alert image.
- Automatically dims screen brightness via the premium feature.
