Scam
Response from developer
Hi! Thank you for sharing your experience - we’re sorry to hear that it caused frustration. This is a real, working technology - not a scam. Our app uses the camera and light to detect tiny color changes in your fingertip caused by blood flow. This method, called photoplethysmography, is used even in some medical devices - but it’s sensitive to proper finger placement, lighting conditions, and motion. Your phone’s camera and flashlight act as an optical sensor: 📍 When you place your fingertip over the camera, the app tracks how light is absorbed and reflected as your heart beats. 📈 This creates a pulse wave, and from this wave, the app calculates your beats per minute (BPM). If you received pulse readings without placing your finger on the camera, that’s definitely not expected behavior. It’s possible the app was trying to find a signal and misinterpreted background noise. We’re already working on improving signal detection and error handling in such cases. We’d love to fix this for you - please contact our support team at support@digitalenter.org, and we’ll assist you directly. Thanks again for your feedback - it helps us make the app better for everyone.
