One thing that would make beeper better than other options (eg self hosted matrix) would be the ability to combine multiple accounts from each service. I have multiple telegram, WhatsApp and discord accounts.
Not the OP, but the beeper client looks better and has native GIF support, among other niceties that more "normal" users would prefer over other clients.
Will the new Beeper app gain support for Fitbit as the "Messaging" app? Before I could select Beeper, Google Messages, or WhatsApp. The new app isn't recognized by Fitbit as an SMS messaging app.
Is there still plans for supporting multiple G Apps accounts?
Having the features and polish of the first party app, but with a user-controlled backend (like how Bitwarden does it) would be great.
BTW, I have a Pebble on my wrist right now :)
