If you want a easy, reliable and cross-platform way to share files between computers, phones, etc, it may be of your interest.
Answering the question you meant to ask, blueray is a physica… just kidding.
LocalSend is basically like bluetooth file sharing over WiFi. Bluetooth, especially the fallback 2.0 is notoriously slow and short ranged. The situation got better with BLE, 5.0 and Long Range. Still, both devices need to speak BT. Ap*le’s iOS is well known to ignore BT file sharing capabilities while implementing own proprietary solutions. On desktop, the situation is still bad. I once tried to send a file between two Windows machines via BT, and it was a horrible user experience. LocalSend (and similar) fix this by implementing cross platform apps and using readily available API’s to share files with few clicks and reasonably high speed between a plethora of devices. I guess, if you don’t have the aforementioned problems, you won’t need LocalSend et al.

So that’s why my Bluetooth file transferring back in like 2015 was slow as balls! I also assumed it was the devices I had. Lol. Which is weird considering I could have sworn I had also done BT file transfers with other devices previously and it seemed a lot faster. (None of these were Apple devices).

Rude.
