Valix vs VitalLens

Your heart rate, from your camera. Valix uses remote photoplethysmography (rPPG), a camera-based technique that detects subtle color changes in your skin caused by blood flow, to estimate your heart rate without any physical contact. How it works Simply hold your phone in front of your face for 30-60 seconds. Valix's AI analyzes the video in real-time to extract your pulse signal and estimate your heart rate. Our CNN model was trained on the Multi-Camera Dataset for Remote Photoplethysmography (MCD-rPPG), a research dataset from the peer-reviewed paper "Gaze into the Heart: A Multi-View Video Dataset for rPPG and Health Biomarkers Estimation." Transparency built in Every measurement includes a confidence level so you always know how reliable the reading is. Valix shows you what it observes — nothing more, nothing less.

Most health apps show you data. VitalLens tells you what it means. Every morning, VitalLens reads your Apple Health data — HRV, resting heart rate, sleep, wrist temperature and activity — and turns it into a single Health Today score from 0 to 100. No athletic jargon. No confusing charts. Just a calm, honest sentence that tells you how you're likely to feel today, and why. YOUR SCORE, YOUR BASELINE VitalLens grades you against yourself, not against averages built for elite athletes. It learns your personal normal over time, so a score means something specific to you. A tappable Why breakdown explains exactly what moved your number — in words that make sense before your first coffee. YOUR ENERGY, ALL DAY LONG The Energy Reserve is a live charge that mirrors your body throughout the day. It tops up while you rest and draws down as activity and stress accumulate. Check it any time on the app, your Home Screen widget or your Apple Watch to know whether to push on or take a breath. RECOVERY AT A GLANCE Each morning you get a simple status: Well Recovered, Recovering or Strained. It's drawn from your overnight HRV, resting heart rate, wrist temperature and sleep — the same signals sports scientists use, translated into plain language anyone can act on. FOUR GAUGES, ONE CLEAR PICTURE Energy, Stress, Heart Health and Sleep each get a plain-English gauge updated daily. Tap any one for a straight-talking explanation of what's driving it. Trend arrows and a 30-day outlook show you where things are heading, so you can spot patterns before they become problems. HABITS AND COACHING BUILT AROUND YOU The Habit Discovery engine quietly looks for personal correlations on your device — things like "your stress gauge is lower on days you walk more than 6,000 steps." No health data leaves your phone. The VitalLens AI Coach goes further: chat about any metric in plain English, or follow a guided Goal with a personalised AI roadmap built around your real numbers.
