It's not an Airdrop competitor if it doesn't even meet the basic requirement of Airdrop - to be able to arbitrarily send a file to someone without being on the same network.
I understand that, and LocalSend looks great for what it does. But AirDrop is so insanely useful to many of us because it allows us to share a large file with a person, regardless of whether we are on the same network or whether there is a network at all. If you need that and you can't, it's quite frustrating.
The original post was about being an AirDrop alternative, which it really wasn't.
