Frequently Asked Questions
Is my camera video uploaded or recorded?
No. Everything runs locally in your browser. No video or camera data is ever sent to any server.
Why is my webcam showing a black screen?
Usually a permissions issue — check that your browser has camera access allowed, and close any other apps (Zoom, Skype, Teams) that might be using the webcam.
What resolution do I need for video calls?
720p at 30 FPS is sufficient for Zoom, Google Meet, and Teams. Most platforms cap at 720p anyway.
How is the quality grade calculated?
We measure brightness, contrast, sharpness, and noise from your live feed. Each gets a score from 0–100, combined into an A–F letter grade.
Does this work on phones and tablets?
Yes. Works on any device with a camera and modern browser. On mobile, switch between front and rear cameras using the Facing dropdown.
