GlowPulse uses rPPG, the same technique used in clinical camera-based heart rate monitoring, to detect subtle color changes in your face caused by blood circulation. Live BPM in your menu bar, Pomodoro sessions with heart rate charts, HRV data during breathing exercises. $2.99, 100% local, no wearable.
🔥 Our Take: rPPG has been in hospital settings for years. This puts it on your desk for less than a coffee. If you've ever sat through a difficult conversation and wondered whether your stress response was real or you were imagining it, your camera now has an answer. The $2.99 price is the point: there's no subscription, no Apple Watch, no chest strap. It either works well enough on your face or it doesn't.
