Questions About Face Scanning

Every heartbeat pumps blood through the tiny capillaries in your facial skin, causing microscopic color changes. While invisible to human eyes, cameras can detect these subtle variations. Our rPPG technology analyzes these color patterns to calculate your heart rate, determine heart rate variability, assess stress levels, and estimate blood oxygen - all from facial video analysis.

Nothing at all. Use Face Scan is completely contactless. Simply open the app, position your face in the camera view, and look at your screen for thirty seconds. Your phone sits wherever is comfortable - you can even prop it up and go completely hands-free during the scan.

Our facial rPPG technology achieves 99.2 percent accuracy compared to clinical reference devices. This rivals the accuracy of high-quality wearables while requiring no physical contact. The technology has been validated in peer-reviewed studies and continuously improves through machine learning advances.

Moderate, even lighting produces optimal results. Natural daylight or standard indoor lighting both work well. Avoid harsh shadows across your face or extremely dim conditions. Our algorithms adapt to various lighting situations, but consistent illumination of your face improves accuracy.

Light to moderate makeup typically does not impact results significantly, though very heavy coverage might reduce accuracy slightly. Facial hair is generally fine as the technology analyzes visible skin areas like cheeks and forehead. The algorithms adapt to individual facial characteristics and find sufficient skin area for reliable readings.

Your facial data remains completely private and never leaves your device. All rPPG analysis processes locally on your smartphone. We do not store, transmit, or have any access to your facial images or video. Your face scan exists only during the brief analysis period, then only the calculated health metrics remain.
