When your child's behaviour feels overwhelming, know what to do next
Thymos helps you understand what your child's behaviour is really communicating — and guides you, step by step, in what to do next.
Thymos is available now on the App Store and Google Play.
Trusted by parents and educators supporting children every day
Grounded in CBT
Evidence-based approach to understanding and responding to behaviour
Built from real experience — not just theory
Thymos was created by a school leader with over 17 years of experience working directly with children, parents, and teachers.
After years of supporting behaviour in real classrooms and conversations with families, one thing became clear:
The key to changing behaviour is understanding what's driving it.
But unlike traditional approaches, Thymos is shaped by real-world experience, making it practical, accessible, and designed for everyday parenting moments, not just clinical settings.
This is support you can rely on in the moments that matter most.

From reactive to reflective parenting
A simple, structured method grounded in CBT that helps you understand behaviour, and respond differently, in real moments.
Talk through the moment
Describe what's happening. Thymos guides you through the moment, helping you understand what your child is feeling and why.
Build your understanding
Access the Learning Hub to learn simple, evidence-based (CBT-informed) strategies so you feel more confident in everyday situations.
Notice patterns over time
Use the Journal to track moments, triggers, and feelings so you can see what's really driving behaviour — and respond more consistently over time.
Respond differently
Bring everything together to respond calmly and consistently using a method that's proven to work. Small changes in how you respond create meaningful changes in your child's behaviour.
