GlowPulse for iOS - Your iPhone's camera is now a heart-rate sensor

Hey Product Hunt! 👋 Six weeks ago I launched GlowPulse here as a Mac menu bar app (#12 of the day – thank you!). GlowPulse for iOS is a standalone iPhone app – not a companion, not a remote display for the Mac version. The full measurement runs on the iPhone itself: point the front camera at your face, and rPPG picks up the microscopic color changes in your skin caused by blood flow. You get: - Live BPM, updated every second - HRV during guided breathing sessions (5s in / 5s out) - Pomodoro focus sessions with a live heart-rate chart - Quick Check – a 30-second stress snapshot vs your personal baseline - An hour-long trend graph - Optional Apple Health export (heart rate + HRV) Everything stays on-device. Camera frames are processed in memory and discarded – never recorded, never uploaded. No account, no analytics, no trackers. That was non-negotiable on the Mac and it's non-negotiable here. One purchase covers both iPhone and Mac (universal purchase): full 3-day free trial, then 3 free readings a day, Premium at $4.99/year or $9.99 lifetime. On accuracy: since the Mac launch I bought a Polar H10 chest strap (the clinical reference standard) and I'm validating the algorithm against it – happy to share data and details in the comments. I'm here all day – ask me anything about rPPG, the on-device pipeline, or why your camera can see your pulse when you can't. 🙏
