That's the crash detection feature; the feature referenced in this article is the ability to use satellite communications in the event that you need help but don't have cell phone reception.

This feature is such a good addition. It was a big reason I upgraded to the iPhone 14 pro last year. We do a lot of hiking as a family and even though most of our hikes take place in the surrounding areas of a major metropolitan region, we often find ourselves in spots with no cell phone reception. Having the ability to call for help in those areas, while I may never actually need it, is a nice feeling.

Thank you for working on this! I love Mlem and am excited to see how it develops.

Very excited to see this! Any place/site we can follow progress and maybe get access to a TestFlight link once available?
