QVitals

Qvitals turns your iPhone into a private, on-device wellness check-in. Cover the rear camera and flash with a fingertip, or look into the front camera, and Qvitals reads the subtle color changes during a guided scan to show your pulse, heart-rate variability and breathing-rate trends — in seconds, entirely on your device. No wearable. No account. No upload. Nothing ever leaves your phone. TWO WAYS TO CHECK IN • Fingertip signal: rest a fingertip over the rear camera and flash for about 20 seconds. Qvitals reads the tiny color shifts as your pulse moves through your fingertip and shows a pulse trend with a signal-quality score. • Face signal: hold the phone at eye level in steady, even light for about 30 seconds. Qvitals reads subtle color shifts in your skin to estimate pulse, beat-to-beat variability and breathing rate. WHAT YOU GET • A pulse (heart-rate) trend after every check-in • Heart-rate variability (HRV / SDNN) context • Breathing-rate wellness trend • Plain-language context for every number — what's typical, what your reading suggests • Trends over time, because a range beats any single number • A live signal preview and quality meter while you scan • Local history and CSV export PRIVATE BY DESIGN Every frame is processed locally. No photos or video are saved, no data leaves your phone, there's no sign-in and no tracking. Your check-ins live only on your device. DESIGNED FOR EVERY DAY A calm, modern interface with full Dynamic Type and VoiceOver support, light and dark themes, and a unified daily snapshot of your wellness trends.
