As the world marks World Mental Health Day 2025, stem4 is shining a spotlight on the mental health challenges facing young people across the UK and the urgent need for accessible, effective support.
At stem4, we know that small, everyday actions can create lasting change. From classrooms to communities, from one-on-one conversations to peer-led campaigns, young people are taking charge of their wellbeing and stem4 is here to make sure they have the tools to do it.
Digital Tools That Make a Real Difference
Our award-winning apps (Calm Harm, Move Mood, Clear Fear, Combined Minds, and Worth Warrior) empower young people to manage their own mental health and support their friends. Over the past year, these tools have reached more than 5 million downloads worldwide, helping young people take proactive steps toward positive mental health.
Behind every download is a story of courage and resilience. A teenager using Calm Harm to cope with overwhelming feelings. A student turning to Combined Minds to support a friend in distress. These individual actions are building a culture of empathy, understanding, and peer support in schools and online communities.

“This World Mental Health Day, we are reminded that young people’s voices must be at the centre of the conversation”
“Early help, digital innovation, and accessible support can transform lives. No young person should face mental health challenges alone. We call on schools, families, policymakers, and businesses to join us in building a future where mental health is understood, supported, and valued.”
Supporting Mental Health in Schools
Schools are uniquely placed to nurture resilience and promote positive mental health. stem4’s Clear Fear for Schools programme embeds the award-winning Clear Fear app into everyday school life, equipping students to:
-
Understand anxiety
-
Identify triggers
-
Manage anxious thoughts and feelings
Using evidence-based Cognitive Behavioural Therapy (CBT) techniques.
“Clear Fear bridges a critical gap in care and empowers young people with practical skills to manage anxiety when professional support isn’t immediately available”
“There is a massive need for schools to support students struggling with anxiety every day, but our teachers often lack time, resources, and expertise to reach every student. Having a clinically validated resource like Clear Fear, which students can access instantly, makes a real difference. We’re excited to start using it to provide immediate, evidence-based support when it’s needed most.”
