Kids and teens spend years learning about the world around them, yet receive very little education about themselves.

Know Yourself brings the science and art of being human into their hands through bite-sized lessons, quizzes, and real-world activities. From how their bodies work and why they feel certain emotions to healthy habits and life skills, they see how what they're learning connects directly to the life they're living.

Instead of simply memorizing facts, they begin to recognize how everything works together — knowledge they can carry far beyond the lesson.

WHY KNOW YOURSELF
Understanding yourself is a foundational life skill. When kids and teens understand how they think, feel, grow, move, and experience the world, they gain knowledge they carry far beyond a lesson.

Because learning about yourself isn't just another subject. It's learning for life.

FOR PARENTS AND EDUCATORS
We're a small but mighty team, passionate about health literacy, building this with input from doctors, teachers, and child psychologists. Reach us at kyapp@knowyourself.com or learn more at knowyourself.com.

Crisis support information is built into the app and never gated behind a subscription. If your child is in crisis: call or text 988, or chat online at 988lifeline.org.
