MeshOS
Private messages & sharing for your people.
No account. No server for your messages.
No one reading what you write.

- Scroll down and tap Add to Home Screen, then Add
- Open MeshOS from your home screen once — after that, flight mode is fine
Share it with your people
Point a phone camera at this — it opens MeshOS
How it works
Install it once and it's yours. It opens instantly, works with no signal at all, and what you write stays on your device — not on a company's computer.
The app makes a key on your phone — that key is you. Nothing to sign up for, nothing to leak, nobody to sell your details to.
You connect straight to people you trust — your messages go phone-to-phone, encrypted, with no server between you. Joining up is two codes swapped over anything you already use (WhatsApp, SMS, a note). Honest bit: that little dance is the price of having nobody in the middle.
Make a group, share its name, coordinate. Messages hop phone-to-phone through the people between you — no group server to seize, no account to ban. Honest bit: anyone connected who knows the group name is in, and people you link with can see your network address. Privacy from platforms — not invisibility.
MeshOS writes a diary where every entry is chained to the one before. Open the toolkit and tap verify the ledger any time — a broken or edited chain shows up instantly.
No internet? Still works.
Save the app as a file (button above) and send it phone-to-phone — the whole app travels in one file and runs the moment it arrives, no internet needed. To keep messages on the new phone, open the link once when it's back online and install properly. Best between Androids and computers; iPhones are happier with the link.
Starlink is internet from space — so just open the link, and add MeshOS to your home screen while you're at it. It only needs the internet once, to arrive. After that it works with the dish off — and friend links still work dish-on, straight across the internet.
Long-range radio needs a small gadget (an ESP32 bridge, about the size of a matchbox) — and the driver for it, which is the next build. The rail is on the dashboard so you can see it's planned, not faked: we'd rather tell you that than light a fake lamp.
Curious how the machine actually works? Open the toolkit — the raw mesh console, for tinkerers.
MeshOS
Your messages. On your phone. No one in the middle.
No server. No account. No platform. Your identity is a key made on this device; your state is 7 rings folded to one integer; every message is a signed wire (~12-byte envelope plus signature); every action lands on a SHA-256 witness chain anyone can check. Installs as an app, works offline, exits with you.
Who's here
Pre-pin a friend's key (advanced)
Normally keys are learned on first hello (TOFU). Pre-pinning a name + public key here means a later hello claiming that name with a DIFFERENT key gets a fresh name instead of silently replacing your friend.
Connect a friend — direct, phone to phone, works across the internet
One of you taps Make an invite and sends the code to the other over anything you already use (WhatsApp, SMS, email). The other pastes it below, taps Use what's pasted, and sends back the reply code it makes. Paste that reply back here, tap Use what's pasted — connected. Two pastes, no server.
