GlowPulse

TL;DR

An app that turns your Mac's webcam into a heart rate monitor by tracking subtle color changes in your skin.

Who is this actually for?

Remote workers and biohackers who want to track stress levels without wearing a fitness tracker or chest strap.

The Good

• No extra hardware to buy or charge since it uses the camera you already have.
• Low-friction way to check your pulse during a stressful workday.

The Catch (Potential Downsides)

Lighting conditions and head movement will likely make the data noisy and unreliable compared to a dedicated sensor. Also, having your webcam active constantly just for a pulse check might feel a bit invasive for the privacy-conscious crowd.
