There's a moderately useful one I've used quite a few times: https://snapdrop.net/ https://snapdrop.net/ It _imitates_ the AirDrop UI, but is not compatible.

There's a moderately useful one I've used quite a few times: https://snapdrop.net/ https://snapdrop.net/ It _imitates_ the AirDrop UI, but is not compatible. Use case is you open up snapdrop.net on both devices (nearby? same wifi?) and you can send files between, but I believe it all goes through a central server. Great for sending a few photos from phone to laptop or linux device when AirDrop isn't an option.
