Zutsu Note for businesses

Zutsu Note is a free headache diary app built by a headache specialist in Japan (“zutsu” means “headache” in Japanese). We work with companies on projects that help people with headaches.

How we can work together

• Research and surveys

  Surveys of people who log their headaches, designed with a headache specialist. People choose whether to take part, and results are shared only in a form that doesn't identify anyone.

• Clinical trial outreach

  Information about clinical trials, shown to people who may be interested. People decide for themselves whether to contact the study team.

• Sponsorship

  Sponsorship of educational content and features, following our rules for health information.

Where we are today

Most Zutsu Note users are in Japan today. Our US edition is new, so programs in the US will open as it grows. We're also happy to talk about projects in Japan.

What we stand by

• We never steer people to a specific clinic or doctor.
• Medical content is reviewed by a headache specialist.
• We don't give companies information that identifies a person.
