Due to circumstances beyond our control, we are no longer able to offer the mContain app and its associated services to communities and organizations throughout the United States.

Despite our continued efforts, we regrettably must say that mContain will not be approved in a usable form for Apple iOS smartphones, forcing us to cease its development and operations in both the Apple App Store and Google Play Store. This project does not merit continuation without the inclusion of Apple smartphone users.

The mContain website will remain online as a reference to the efforts of our team and collaborators, including the office of legal counsel at The University of Memphis and the office of Attorney General for the State of Tennessee. All those involved donated much of their time and effort to provide a way for our community to help manage the COVID-19 pandemic. We are thankful to say that these efforts will not go to waste. The learning experiences and technological advances achieved through mContain work will provide foundations for future projects and influence decisions as new opportunities arise to advance our team science and software development going forward.

The mContain team would like to give a heartfelt show of gratitude to everyone who supported this project. THANK YOU.
