About Us

OHIOH gives them the ability to stop Covid19 via mobile phone app.

We have developed software that uses 3 different technologies to protect your health. With or without personal data.

We work with the big players in the IT world. Through open source, all our modules are visible in the application. Visit us on our github page.

OHIOH is a volunteer-led effort to fight COVID-19. Are you a developer? A public health expert? A writer? We want your help.

Our organization is here to make a difference, not a profit. We need your support to slow the spread.

OHIOH works best when a community adopts it together. Are you looking for an app to help protect your state? Your company? Your country? Let’s talk.

We are working with partners that share our commitment to health and human rights. If your organization has expertise or tools to help stop the spread, let’s work together.
