Trusted by Parents
Welcome to FeverCoach
A child's fever at 2 AM is frightening. We know — our doctors have spent years answering exactly these questions from worried parents. FeverCoach exists to give you the guidance, context, and reassurance you need in those moments.
FeverCoach comes from the team behind "Yeolnayo," South Korea's leading pediatric fever app, trusted by millions of Korean parents. FeverCoach is entirely redesigned for North American families.
FeverCoach learns about your child — age, weight, and fever history — so the guidance you receive about your child fits the child's situation. Behind it all is clinical content developed and reviewed by our physician team.
Last but not least, your child's health data stays private. We protect it to HIPAA security standards, and it's always yours — delete your account, and your data is deleted with it.
