RadioMail is a modern email app for off-grid communication on iOS. It is designed to provide a beautiful and intuitive experience for sending and receiving messages over amateur radio, using the Winlink network.

Winlink is a global network of amateur radio and authorized government stations that can carry email when the internet is not available. It is operated by licensed radio amateurs and supports attachments, position reporting, and interoperable emergency communications.

A valid amateur radio license is required to use this app.
