Licence-free spectrum 915 MHz ISM in the Americas, 868 MHz in Europe. Chirp-spread modulation punches through concrete, granite and body tissue at a fraction of a watt. There is no carrier to bill you and no SIM to seize.
Delivery you can't miss No screen, no chime, no vibration lost in a coat pocket. The TX-1 addresses a nerve bundle with 400 mm of dense innervation, so a message registers at the receiving end within 40 ms of arrival. Read receipts are involuntary.
End-to-end, genuinely Curve25519 key exchange, per-hop re-encryption, and no plaintext anywhere but the two endpoints. Relaying nodes carry your traffic without ever being able to read it. Nothing is stored. Nothing is retained.
STEP 01 — ENCODECompose without a keyboardSqueeze twice to open a channel and tap your message against the actuator, or dictate from the companion app over Bluetooth LE. Text compresses to a 14-byte frame before it ever hits the air.
STEP 02 — RELAYBorrow the crowdYour frame broadcasts to every node in earshot. The one with the best route to your recipient claims it, re-encrypts it, and passes it on. Nobody in the chain learns who sent what.
STEP 03 — RESOLVEArrive as sensationThe recipient's node decrypts the frame and renders it as a pulse train on the dual LRA array. Contacts get their own signature rhythm. You learn to read them in about a week.
