How it works

The Mightier Mechanism

Emotional regulation is the relationship between understanding emotions and reacting to them. It is an internal ability that kids develop over time. A personal, physical experience that takes practice.

Mightier turns emotional regulation into a game. Kids see how their frustration, anxiety, or excitement directly influence their heart rate. They learn that things become more challenging when their heart rate is up, and they’re motivated to explore various calming strategies to bring it down and continue playing. They practice quickly, in the moment, while having fun, in a way that strengthens their natural ability to regulate their emotions in real life.
