At a concert or festival
Thousands of phones crowd the same masts and mobile data grinds to a halt. Message the friends you came with anyway.
Secure chat without internet
No signal. No Wi-Fi. Still talking.
Meshveil turns the iPhones around you into a private messaging network over Bluetooth. Message someone nearby, or let other Meshveil phones carry your message further, hop by hop.
Free for iPhone. No account, no phone number.

- Free
- Every feature is free for everyone.
How it works
Further than Bluetooth alone.
On its own, Bluetooth only reaches the phones close to you. Meshveil phones pass messages on to one another, so yours can reach someone well beyond your own range. Every phone that joins extends the reach, and phones that pass a private message along carry sealed data they cannot open.
Open Meshveil
Nearby iPhones find each other over Bluetooth. There is no network to join and nothing to set up.
Send your message
Direct messages and private-channel messages are encrypted on your iPhone before they leave.
It finds a route
Other Meshveil phones carry it further. You can see whether it is waiting for a route, has been picked up by another phone, or has arrived.
Where it helps
Made for the places networks give up.
Out in nature
Campsites, trails, and the backcountry, where there was never a signal to begin with.
When the neighbourhood is offline
If the internet goes down on your street, neighbours who have Meshveil can still message each other, phone to phone.
On the move
Trains, flights, and stadiums: keep talking to the people travelling with you.
Teams without a network
Keep your team talking where there is no signal: remote sites, events, film sets, farms, and boats.
At protests and large gatherings
Mobile networks are often overloaded or shut down, and it matters who can read what you send. There is no account or phone number to tie you to Meshveil, and private messages are readable only by the people they are meant for.
A mesh, not a walkie-talkie
Nearby is only the start.
The Network tab shows two groups: people near you, and people you can reach. Reachable includes those you can only get to because other phones pass your messages along.
- Every phone that joins extends the network’s reach.
- Messages find their own route, hop by hop.
Invite-only channels
A private space for your crew.
Public rooms for everyone around you. Private channels for your group: invite with a code or a short-lived link, and remove people when you need to.
- Send text, photos, voice notes, files, and places.
- When a member is removed, a fresh key protects the messages that follow.
Trust you can check
Know who you’re talking to.
Verify someone in person by scanning a QR code or comparing a code. See plainly who has been verified, and get a warning if someone’s identity key changes.
- Choose who can see you nearby, from everyone to no one.
Safety on your phone
Safety without a server.
Block anyone and they disappear from your screen. Report a message straight from the conversation. Hide media and muted words from people you don’t know.
- It all runs on your iPhone.
Privacy when you leave
Your conversations. Your lock.
Lock the app with Face ID, Touch ID, or a PIN. With the lock on, notifications and the app switcher show nothing private.
- Meshveil tells you when a screenshot or recording is taken.
Serious security
Encrypted end to end, by default.
Direct messages and private-channel messages are encrypted on your iPhone before they leave. Only their recipients can read them; relay phones carry sealed data.
Double Ratchet
Direct conversations use the Double Ratchet, through the open-source vodozemac library.
Forward secrecy
Keys move on with every message, so a key taken from a phone later cannot unlock earlier messages.
Fails closed
If a message cannot be encrypted, it is not sent. It is never quietly downgraded to plain text.
Signed public rooms
Public-room messages, receipts, and presence are signed, so nobody can pose as someone else and appear verified.
Encrypted on your phone
History, photos, and files are stored encrypted, with keys that never leave your iPhone.
No central copy
With no account and no server, there is no central store of your messages to breach, leak, or hand over.

Good to know
What Meshveil can’t do.
- Meshveil needs other people nearby using Meshveil to form a network, and delivery depends on the phones and routes available at the time.
- Public rooms can be read by anyone in range.
- Nearby devices can tell that a phone is using Bluetooth, and phones that relay a message can see when it was sent and how large it is, but not what it says.
- Meshveil is not an emergency service.
