The Masked Manual

Open source iOS app for referencing face mask data

The Masked Manual on the iOS app store: https://apps.apple.com/us/app/the-masked-manual/id1542536599

The problem:

Masks are important. Choosing the right type of mask and understanding its qualifications is critical. Currently, mask information is scattered between the openFDA database, FDA websites and CDC websites.

The solution:

“The Masked Manual” is a free iOS app that shows mask information compiled from openFDA, FDA websites and CDC websites. It lets you easily search for masks and see their qualifications, as well as instructions for wearing it. You can also use the camera to recognize and find your mask by scanning its packaging.

Screenshots from the app. 2000+ masks are included.

At the time of writing, the following masks are referenced:
