Draw a Perfect Circle in the Air!
It's incredibly tricky! Step back from your webcam, hold up your finger, and try to sketch a mathematically perfect circle in the air. How steady is your hand?
How It Works
Just open the app. No downloads required. When prompted, allow webcam access (processed 100% locally and privately).
Raise your index finger, pinch it with your thumb to grab your digital pen, and start drawing right in the air!
