How It Works

From setup to notification in 10 seconds.

1

1. Select Window

Grant permission to view a specific application window.

2

2. Crop Region

Draw a box around the progress bar or status text.

3

3. Get Notified

We watch the pixels. You get a notification when they change.

The Privacy Shield Architecture

Verify it yourself: We process pixels, not video streams.

Standard Tools (TeamViewer/Discord)

HEAVY UPLOAD

Your screen is constantly streamed to a 3rd party server.

GreenBar

ONLY "DONE" SIGNAL

Local Pixel Analysis. No video ever leaves your device.

Take the "Airplane Mode" Challenge

GreenBar works entirely offline if you only need an audio chime. You can literally disconnect the internet and it will still monitor your pixels locally using the Canvas API.

No video data ever leaves your device.

Local by Default. Cloud by Choice.
