Understand your mental health, one step at a time.
The PHQ-9 Self-Assessment app helps you reflect on your emotional well-being using a clinically validated tool. With a simple and clear interface, you can complete a PHQ-9 questionnaire, view your history, and monitor changes in your mood over time.
The PHQ-9 (Patient Health Questionnaire) is a widely used screening tool for identifying and tracking symptoms of depression. This app is based on that tool but is not a replacement for a mental health professional.
Important: This app does not provide medical advice, diagnosis, or treatment. It is not a substitute for therapy or consultation with a qualified mental health provider. The results of the PHQ-9 questionnaire are for informational purposes only and should not be used to make healthcare decisions.
This app allows you to begin a new PHQ-9 questionnaire at any time. You can also access a list of all your previous assessments with dates and scores clearly displayed. Scores are color-coded to make it easy to see trends at a glance. The app supports multiple languages.
All questionnaire results are stored securely on your device using the iOS Keychain. No data is shared externally, and no account or internet connection is required. Your privacy is fully respected.
Mental health is dynamic. Checking in regularly helps you stay aware of how you’re feeling, spot patterns, and take early action when needed. The app is designed to be quick, private, and easy to use.
Download the app to start your first self-assessment in under a minute.
