XPRS

XPRS is a messenger and app launcher that works off the grid. It talks over the internet, over a Reticulum overlay, and straight over Bluetooth LE, and it stitches those together so a message or a file gets to the other side over whatever path happens to be up. If there is no internet, it falls back to a Bluetooth street mesh and long range radio. If there is internet, it uses it. There are no accounts, no phone number and no server in the middle. Your identity is a key the device makes itself. What it does

• Many transports at once. A message can go out over the internet, over Bluetooth LE, or over Reticulum, and whichever copy arrives first wins.
• It keeps working with no internet. A Bluetooth street mesh passes messages from phone to phone with nothing in between, and cheap LoRa stations push that reach out over kilometres.
• Store and forward. A message for somebody who is away is carried by the stations in between and delivered when they come back.
• Chat. One-to-one conversations, closed groups and a local room, with pictures and files.
• Social. Posts, replies and follows, spread over the same transports.
• Torrents and shared folders. Files move peer to peer, from whoever has them.
• Wapps. Small WebAssembly apps that draw through one shared native interface and use the host's transports: chat, social, mail, a media player, a file browser and more. You can install others, or write your own in the built-in editor.

* Chat: each room has a notifications switch; the busy Global room is quiet by default.
* Chat: a direct message to someone whose key is not known yet waits and is sent sealed once the key arrives, or can be sent unsealed now.
* Chat: Info opens a full page with the original text, the route through relays and how the message was received.
* XPRS runs with whatever permissions you grant.
