Stolo is an encrypted messenger that built off of Reticulum and LXMF Out of the box it is a private, end-to-end encrypted messenger: no account, no phone number, no sign-up. Your identity and your history live only on your device, and Stolo's gateway relays your messages across the internet. When you need more, the same app becomes your own network. Create a network, share one invitation, and everyone who joins is in each other's contacts, trusted, automatically. Phones link directly over Wi-Fi and cellular, and optional long-range LoRa radios carry messages where there is no signal at all. Messages to someone out of range wait and are delivered when they come back. What you can send, on or off the grid: • Messages, photos, and voice notes, end-to-end encrypted. Only the people in the conversation can read them. Not us. • Live GPS positions on a built-in offline world map. See yourself and your team with zero connectivity. Under the hood, Stolo is built on Reticulum, the open cryptographic mesh stack, and sets up in a minute with no config files. Used for backcountry trips, maritime, job sites, disaster response, and everyday group chats that should stay between the people in them. Built on privacy. Works every day, everywhere, and keeps working when nothing else does.

• NomadNet pages: open pages people publish on the mesh from the new Pages tab, and write and publish your own pages straight from your phone. Block or report a node you don't want to see. • Your name in a network is now sealed in the network directory, so only the network's members can read it. Members still on an older version of Stolo see people who have updated as a short code until they update too. • Much better battery life in the background. Stolo now rests between check-ins while your messages keep arriving, and shares your position once an hour instead of every minute while it's in the background. • Choose what each connection does in the background: stay connected, or disconnect when idle to save more battery. Find it in Connections. • Smoother switching between Wi-Fi and cellular. When Wi-Fi drops, your messages move to the gateway within seconds, and Stolo goes back to Wi-Fi within seconds when it returns. • Each message now shows the connection it actually arrived over. • A priority message that can't be delivered now expires after 7 days, and you can cancel one that's still waiting. • The "Mesh degraded" notice now says what to do, and no longer appears just because you switched networks.
