just search seytonic bluetooth on yt , you can find it preety easily ngl
speek sucks in my opinion , i tried it ,
tbh jami is the best app currently in the p2p messenging space
berty sounds good as well , its built on top of ipfs and weshgaurd
tox is good as well
(i have messaged briar and berty team regarding some questions and i havent gotten its answer , i will update you when i get the answer)
https://www.securemessagingapps.com/ if you see closely for session , it says that attachments are centralized in their servers in canada
session tries to promote their oxen cryptocurrency and lokinet which imo crypto currency are used by baiters to bait people into ruining their money
you dont understand what signal /molly is , do you ? they are centralized server and OP specificially asked not centralized server / server for that matter
matrix is good but it still need server , plus matrix.org takes quite a bit of metadata
jami’s good but it uses turn server to verify your name
briar’s bluetooth functionality can be violated plus no good ui/ux
db0 , i really like your server tbh but my monyet.cc is serving me currently well the fact that you have a photon , tensorrect etc as alternate frontends is kinda cool as well :p thanks man , we as a community appreciate your instance and its c/piracy -fellow pirate
