MoodTools
A free mobile toolkit for depression screening and CBT-style mood support.
MoodTools is a smartphone app offering self-help tools for people dealing with low mood or depression. It includes a PHQ-9 depression questionnaire with symptom tracking, a cognitive-therapy-style thought diary, and a suicide safety plan with emergency resources.
Why it stands out
- Uses the PHQ-9, a widely used depression screening questionnaire, rather than a casual mood quiz.
- Combines day-to-day CBT-style reflection with crisis-oriented safety planning in one app.
- Designed as a no-cost smartphone tool, making it more accessible than many subscription-based mental health apps.
- Focuses specifically on depression and negative mood rather than trying to cover every wellness topic.
Good to know
- The app explicitly states that it is not a replacement for treatment or medical intervention.
- Its scope is centered on depression and negative moods, so it may not fit users seeking broader mental health support.
- Crisis tools can help with planning, but they are not a substitute for emergency services during immediate danger.
- The described product is a smartphone app, not a full web-based therapy platform.
Under the radar: Complete the safety plan during a calmer moment rather than waiting until a crisis, so the emergency resources and coping steps are already ready when they are hardest to think through.
