Posture feedback
Gives real-time feedback for slouching, head tilt, forward head drift, and off-center posture while the session is running.
Features
Everything ScreenGuardian helps you notice and measure — all kept on your device.
ScreenGuardian is a desktop awareness tool, not a medical device. It focuses on gentle posture, distance, break, and desk-habit feedback — with camera frames kept on your device and access managed through your account. Free during early access for eligible accounts.
Real-time feedback
Checks and reminders
The live signals ScreenGuardian looks for while you work, so small corrections happen before they become habits.
Screen distance
Estimates how close you are to the display and nudges you when you drift inside your target distance.
20-20-20 reminders
Keeps eye-break timing visible so short visual resets become part of the work rhythm.
Desk habit feedback
Optional real-time feedback for hand-to-face, face-touch, and nail-biting style habits you choose to enable.
Personalized calibration
A quick first-run calibration sets your posture baseline and target screen distance, so feedback is tuned to your body and desk.
Dashboard
Stats, goals, and history
Everything is measured locally, so you can see whether things are actually improving over time.
Session metrics
Shows current screen distance, average distance, screen time, bad posture time, and session alert counts.
Trends and pinned graphs
Records posture alerts, screen time, bad-posture time, and average distance with quick pinned chart views.
Progress insights
Weekly quality view: posture stability, distance stability, break follow-through, and habit-cue trends.
Goals and challenges
Set personal targets and optional custom challenges, then track how often you follow through.
Local history
Stores chart history on your device, so trends stay local to your machine.
Workflow
How it fits on the desktop
Built to run alongside your work, not interrupt it — visible when you want it, quiet when you don't.
Runs in the background
Real-time checks keep running while the main window is behind your work or out of the way.
Picture-in-picture
Offers a compact floating live view when you want posture feedback visible without keeping the full dashboard open.
Alerts-only sessions
Notification mode keeps the live view and real-time alerts available while local stats, goals, charts, and alert history are paused.
You choose what's on
First-run setup lets you pick which checks and reminders start enabled; change them later in Settings any time.
macOS and Windows
Runs natively on macOS and Windows, with the same checks and reminders on both.
Auto-updates
New versions arrive in the app and are verified as authentic before they are offered.
Privacy and access
Local-first by design
Your camera and your history stay on your machine. ScreenGuardian steps aside the moment another app needs the webcam.
Camera stays local
Camera frames pass through the local app in memory for real-time feedback. They are not sent anywhere and are not stored by ScreenGuardian.
No microphone access
ScreenGuardian uses visual posture and distance feedback only. It does not need microphone permission and does not listen to your room.
Manage your devices
Link the devices on your account and sign any of them out yourself, anytime, from the web.
Members-only downloads
Downloads unlock once your account has access confirmed.
Works through short outages
A recently verified account keeps using the app during short network outages.
