FlowingEdge Home Edition auto-discovers the devices in the same group, supports auto-resume of the file transfer, supports sharing from other mobile apps, isolates devices in the same network but belonging to different groups, works natively on iOS, Android, Windows, macOS, Linux.

There are free apps (mainly web apps) that can compete on some of the features, but we feel that our app has an edge on usability and practicality. Last but not least we need to pay ourselves :-)

Yeah, there's also free ones that can do pretty much all that (not just web apps).

They're just as easy, if not easier, to use.
