What focus tracking features matter most to you?

Hey everyone! I'm building FocusLens — a macOS menu bar app that uses your camera to detect whether you're actually looking at the screen, and tracks your real focus time automatically.

It's 100% local (no data leaves your Mac) and uses Apple Vision Framework for face detection.

I'd love to hear: what's the biggest challenge you face with staying focused while working? And what kind of insights would help you improve?

Some features we're considering for future updates — would love your input on what matters most!
