This app is not endorsed by or associated with the US Government, Department of Defense, or any state or local government This app is not for the use in medical decision making or in the treatment, identification, or diagnosis of any illness or injury. This app is a private endeavor to create a space where common documents and tasks are categorized. The initial focus was the aerospace medical provider in the operational environment, but this should be useful for any USN provider looking for common forms. The main focus is in aviation because that’s the field I am in, but the goal is to provide a document repository for commonly used resources. In some areas I provide my thoughts, but these are just my opinions. Also in the resource section are links, apps, and RSS feeds that I felt may be useful. There is a medical calculator that covers CGS, respirator settings, and a burn calculator. This was just a project that was fun, it's not anticipated to be used in a clinical setting. Also in this app I've made a dark mode accessible through the app info page. My hope with this app is to get as much input as possible so that the app can be relevant and up to date. TO aid this there are multiple quick links to a Google document where input can be provided. This is the second iteration, the original app OpMedApp-Flight, had to be discontinued due to programming issues, primarily that I’m not a programmer and goofed it up. This version includes several UI changes to help with the user interface. There’s also a section with general apps, both DoD and civilian, and RSS feeds, also both DoD and civilian. One additional option is a dark mode. This may be accessed in the app information tab: on the home screen select the button in the top left corner, then click on the dark mode box. All referenced materials in the app are open source documents designated for public release. These documents can be found on the Navy Medicine website (https://www.med.navy.mil/) as well as the Air Force (https://www.afrl.af.mil/) This app does not access, collect, use, or share personal information. I do request permission for notifications. This is only to provide notifications on when resources are updated or a new release is available. There is no spam and there is no advertising on this app I do hope there is value added and you find usefulness in the app! (comments can go to admin@opmedapp.com)
