One paragraph.

Lattice is an offline-first, end-to-end encrypted, peer-to-peer messenger for the day the internet doesn't work. It moves messages between phones over Bluetooth and Wi-Fi Aware, with LoRa, Meshtastic and an optional Tor bridge built in to extend the reach, and no servers, accounts or phone numbers anywhere. Your identity is a 12-word phrase that lives only on your phone. The mesh is built to scale to festival-density crowds and to cost almost nothing in battery between uses, so most people install it once and let it sit until they need it. Built by one independent developer. Source opens under the Mozilla Public License 2.0 at v1.0.

Lattice is an offline-first, end-to-end encrypted messenger for the moments when the cellular network and the internet aren't there: government shutdowns, festival crowds, regional outages, disasters. It uses the radios already in every modern phone, Bluetooth and Wi-Fi Aware, to pass messages between phones directly, hopping through other Lattice users in between when the recipient isn't in range. LoRa, Meshtastic and an optional Tor bridge are built in to stretch that reach further. There's no Lattice company server in the middle, no account to create, no phone number to provide. Your identity is a 12-word seed phrase generated on your phone, kept hardware-protected by the Secure Enclave on iOS or StrongBox on Android, and never sent anywhere.

The cryptography is hybrid post-quantum. Every session uses both Curve25519 (the same primitive as Signal and WhatsApp) and ML-KEM-768 (the NIST FIPS 203 post-quantum standard), so even an adversary who later breaks one of them can't go back and read your traffic. Groups use MLS (RFC 9420). The stack opens under MPL 2.0 at v1.0, and the project commits to reproducible Android builds, signed-source attestation for iOS, full publication of audit reports, and a coordinated security disclosure policy. Lattice is a companion to Signal rather than a substitute for it. Most days you'll keep using whatever messenger you already have, and Lattice waits in the background for the day it stops working.

Quick facts.

Logo.

The Lattice mark is a speech bubble silhouette built from a mesh of dots, clustering more densely toward the lower-left corner where the tail reads. It pairs deep ink (#0E1116) on bone (#F5F1E8). Use the SVG wherever you can.

Screenshots.

Eight stills from the iOS app. Identical compositions exist for iPad and Android — drop a note in our Matrix room if you need a specific platform or a full-resolution App Store render (1290×2796).

Founder's letter.

If you want the why-this-exists in the words of the person who built it: /letter. Personal, short, no marketing language.
