Ok my friends isn't in my city, how.
I was reading it like "what kind of pimp calls his msging service, bitch chat?" "bitch at?" "@ a bitch on bitch @?".. up until I saw your msg and realized that wasn't intended.
This idea is absolutely great and welcomed. However, its practicability is quite niche.
why not BTchat, why BIT?
unfortunate name but interesting project
"As users move through physical space, their phones form local Bluetooth clusters and pass messages from device to device, allowing them to reach peers beyond standard range — even without Wi-Fi or cell service."

Bluetooth, no ty.
Did he just reinvent Briar app?
Yet again, thread has been rubenized…
Bt chat is insane due to limits of bt range. You can speak in that range.
It drops shy as soon as it hits the ocean
And would users be informed of a delivery failure?
I won't let my phone-bluetooth-connection always turn-on since nokia with symbianOS.
11 Types Of Bluetooth Attacks And How To Protect Your Devices
"Close" friend means proximity, not importance.
memories ....
This type of software is only useful if you need to communicate with people who are near you. For example, this happened during the protests in Hong Kong, when "activists" could receive instructions and respond to them, and coordinate with each other. However, times have changed since the Hong Kong events, and governments may now block not only mobile and Wi-Fi connections, but also Bluetooth.
Yeah, but he "vibing"-it
