It's not even close to the speed AirDrop has. This is not an alternative to AirDrop. I tried it multiple times but it's slow every time. These alternatives don't use the same technology.

It is an alternative. It just doesn't fulfill all the needs Airdrop does. I've had situation where I want to share a photo or a text file and it'll work great in that scenario.

Probably the main "feature" AirDrop has is speed. Other alternatives should include that "feature".

No it isn't? The main feature is sending things peer to peer.

That's not a feature that's a purpose.

So what? Anyway the more important difference is it requires both computers to be on the same LAN. The main point of AirDrop is you can share between two devices with or without LAN, with or without internet.

It's faster than the standard wireless transfer speed between my iPhone and my Windows PC (0 KB/s)
