Pulselume

See your pulse as a live waveform, then use guided breathing to watch how your rhythm changes. Pulselume turns your iPhone's rear camera into a private, on-device pulse and breathing biofeedback tool. Rest a fingertip over the rear camera and torch, hold still, and Pulselume reads tiny color changes in your skin to draw a scrolling pulse waveform with an estimated BPM. Then follow a guided breathing session and save the result as a personal wellness log. What you can do: - See a live camera-based pulse waveform - Follow guided breathing patterns, including box breathing, 4-7-8, coherent 5-5, and custom patterns - Review a new Read Quality report that checks signal confidence, capture length, waveform detail, rhythm context, and session context before you save a trend point - Save local history with notes, mood tags, charts, streaks, and personal baseline context - Export CSV files and wellness-log PDFs from your own saved readings - Learn how PPG, breathing rhythm, and general-wellness limits work with in-app citations Private by design: - No account - No ads - No tracking - No analytics - No third-party SDKs - No network required - No video saved or uploaded Pulselume is for relaxation, breath training, and curiosity only. It is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent any disease or medical condition. Heart-rate, breathing, variability, calm, coherence, and quality values are on-device estimates that can be affected by lighting, motion, finger pressure, skin temperature, and camera conditions. If you have health concerns, contact a qualified healthcare professional. Breathe in. Breathe out. Watch your rhythm.
