Check your depressive mood, anxiety, and stress levels in real time by measuring blood flow changes in under 1 minute using your smartphone camera.
We provide a scientific analysis of your psychological state, which may not be easily captured through surveys alone.

■ Scientifically Validated and Precise Analysis
- MindCheck is an HRV (Heart Rate Variability)-based mental health assessment tool jointly developed by Yonsei University Severance Hospital and HAII, a digital therapeutics company.
