PainTrace Live

PainTrace is a privacy-first self-monitoring app for on-device review of facial changes, personal baseline comparison, and cautious tracking of pain-expression similarity. The app helps you compare a current selfie photo or short selfie video with your own baseline first, then with a local pain-expression library second. Results are shown as non-diagnostic markers such as visible facial anomaly, baseline deviation, confidence, and trend direction.` `PainTrace is designed for careful monitoring and documentation. It does not diagnose, treat, cure, or prevent any medical condition, and it is not a medical device. It must not be used as a substitute for professional medical advice, diagnosis, or treatment. `The app works locally by default. No cloud backend is required in v1. Raw photos and raw audio are optional. Users can choose privacy-focused storage options, export local reports, and delete stored data from within the app.` Optional features include structured context tags, fixed phrase-reading tasks, and tap-only image tasks. These features provide only non-diagnostic markers and should be interpreted with caution, alongside capture quality and personal baseline history. Confidence scores are shown for each result to reflect lighting, pose, blur, occlusion, and other capture-quality limitations. `Seek urgent medical care for sudden facial drooping, severe swelling, trouble breathing, chest pain, severe headache, or other emergency symptoms. Consult a qualified healthcare professional for medical advice, diagnosis, or treatment.`
