PLEASE NOTE! While Mightier is free to download, a Mightier Membership is required. Find out more at Mightier.com Mightier helps children (ages 6 - 12) who struggle with their emotions. This includes kids who have a tough time with tantrums, feelings of frustration, anxiety, or even a diagnosis like ADHD. Our program was developed by clinicians from Boston Children’s Hospital and Harvard Medical School and is designed to create a fun and engaging way for kids to practice emotional regulation through play….and become Mightier! Players wear a heart rate monitor while they play, which allows them to see their emotions and connect with them directly. As they play, your child reacts to their heart rate. As their heart rates go up, the game gets harder to play and they practice how to bring their heart rate down (take a pause) in order to earn rewards in the games. Over time and with routine practice/play, this creates “Mightier moments” where your child breathes, pauses, or uses one of their practiced cool down strategies automatically when facing real world challenges. Mightier includes: A WORLD OF GAMES Over 25 games on the platform and 6 worlds to conquer, so your child will never get bored! THE GIZMO Your child’s visual representation of their heart rate. This will allow them to see their emotions and connect with them directly. Gizmo will also teach your child emotional management skills when they find themselves in extreme duress. LAVALINGS Collectable creatures that represent big emotions. These will help your child connect with their range of emotions in a fun, new way. PLUS…..for Parents ● An online hub to access a dashboard of your child’s progress ● Customer support from licensed clinicians ● Tools and resources to help navigate your Mightier parenting journey.
