“Continuity. That is Apple’s catch-all term for how iPhone, iPad, and Mac talk to each other. It covers a wide range of small conveniences. Copy something on the iPhone and paste it on the Mac. Start an email on one device and finish it on another. Take a call from the Mac even when the phone is across the room. But, to no one’s surprise, there’s a gap in its support. It doesn’t officially work on Linux. So Zack built Tether, an open source project that replicates pieces of that experience on Linux without requiring a Mac device.”
Yes there is KDE Connect, but apparently Tether goes a bit deeper than that for Apple. So this may be interesting for Apple users to try out with Linux.
