eTherapy App for Children with ADHD



Our App’s personalized 1-on-1 plan makes it easy to do daily tasks (morning routine, homework, bedtime ritual and more). It’s loaded with motivation for children and lots of kudos from others to help kids finish stuff. Parents have an easy-to-follow structure for planning routines, making lists and calming emotions. Our App also includes cognitive and role play games with error pattern recognition to be played exactly when needed. Therapists assign tasks, upload documents, review cognitive game play data and give kudos. We aim to address ADHD core symptoms.

Upcoming User Tests and Studies

Iterative development process including rapid prototypes and evaluation of a variety of game mechanics and styles in user tests and focus groups.

Controlled multi-center pilot study to evaluate efficacy and acceptance of learning and concentration exercises for ADHD, attention-deficit or hyperactive children.


Our aim is the development of a playful cognitive and strategy training to support and supplement therapy of primary school children with attention deficit/hyperactivity disorder (ADHD).

MATS is designed to provide effective and appropriate contextual support to patients, parents and therapists.

Our 360° Research Concept

Meister Cody – ADHD by MATS covers many main areas around ADHD:

  • 1. Main Features

    Child, parent and therapist modules. 45 training days, 3x / week, daily one strategy training unit plus a cognitive game. A success transfer of what has been learned into the daily routine is a critical point. We offer personal or telephone support for parents.

  • 2. Age

    6 – 10 years

  • 3. Child - First Priority

    Our research focuses on helping children. Parents and therapists have access to extra features that assist with the primary goal of supporting the child at home and during therapy sessions.

  • 4. Behavior Therapy Treatment

    Therapists use our app as an integrated part of their practice. In August 2020 we will conduct systematic interviews with therapists.

  • 5. Technology

    An expert blend of digital health and therapy. Gamification with a dual focus on motivation and attention & concentration skills. Mobile first. Available on iOS, Android, Amazon Fire OS. Built with Unity.

  • 6. Strategy Training Focus

    Metacognition, motivation and volition, emotion regulation. Content: mental contrast (MO), anticipatory emotion regulation and situation modification (EM), reactive emotion regulation (EM), signal maps and thinking out loud/self-instruction (MK), if-then planning (VO), self-observation and self-reinforcement (reinforcement plans) (MO), routines (MK + VO). Focus on situations at home that require self-management by children.

  • 7. Cognitive Training Focus

    Executive functions, Metacognition. Content: focused attention, shifting, divided attention, updating, action planning, interference control, inhibition.

How do we motivate children?

We take the motivational effect of computer games strongly into consideration. By closely linking evidence from gamification, entertainment computing and video game research with our clinical development process, a particularly high degree of motivation is to be generated and sustained while ensuring MATS meets the particular needs of children with ADHD symptoms.
