SIGLINK keeps your group talking anyway.
No towers, no internet, no SIM. Every phone running SIGLINK passes your message on until it arrives.
With Extended Reach, up to 255 hops: about 19 km of path through a busy city.
Always end-to-end encrypted. Every phone that passes your message on sees only scrambled data.
Scan a friend's code in person and you know it's really them.
Photos and voice notes travel the mesh like any message, end-to-end encrypted.
Voice and video calls when you need to hear and see each other.
No phone number.
No contact list stored.
No ads, no trackers.
Sign in once with your email. After that, SIGLINK works with no connection at all.
Messages wait in an encrypted mailbox for up to 30 days and reach friends even when their app is closed.
Clear ticks show exactly where each message is: on your phone, sent, delivered, read.
On iPhone, off-grid messaging and relaying work while SIGLINK is open. Range varies with surroundings and how many devices are nearby.
