Hopper builds a live encrypted mesh from the radio chips already inside your iPhone or Android. Here's exactly how a message travels from you to anyone, anywhere, offline.
Message Route — Live Mesh Simulation
Your message securely bounces through nearby Hopper devices until it reaches its destination — even if the recipient is far out of direct range.
One app. No sign-up.
Download Hopper on iOS or Android. No account, no phone number, no email. Just pick a username — your identity lives only on your device, nowhere else.
Find peers. Instantly.
Hopper quietly scans for other phones running the app nearby. When it finds one, they introduce themselves automatically — no pairing, no contact sharing, no permissions dialog.
Route around anything.
Hopper maps out everyone nearby and finds the best path to your recipient. If someone moves out of range, it reroutes through others automatically — you won't even notice.
End-to-end. Every hop.
Each message is sealed before it leaves your phone. The people passing it along can't open it — only the intended recipient can. Nothing is stored anywhere along the way.
