No phone number. No account.
Your identity is created on your device, with a twelve-word recovery phrase that only you hold. Nobody needs your number to reach you, and there is no sign-up.
Own your conversations.
Private messages that go from your device to your friend's, sealed so only they can read them. Your history stays on your device — no server keeps a copy.
Beta · v0.7.1
Windows & Android
One-to-one chats. Messages and files arrive while EchoIt is open on both devices.
Try it — how a message travels
- Sealed on the sender's device
- The helper introduces the two devices
- Sent straight to the other device
- Opened there, and marked Read
A simulation in your browser — nothing you type here leaves this page.
End-to-end encrypted
Windows & Android
No account or number
No ads or tracking
What makes EchoIt different
A messenger for people who would rather their conversations weren't sitting on someone else's server.
Windows and Android, together
The same EchoIt on your computer and your phone. A PC and a phone chat like any other pair — messages, photos, files, reactions, replies and read receipts — tested both ways on real devices.
Only your friend can read it
Every message is sealed on your device and opened only on theirs. The helper that introduces your devices can't read a word, and neither can we.
Your history stays with you
Chats are kept on your device, with the words encrypted. No server keeps a copy. Who you talked to and when is not encrypted on the device, so keep a lock screen on.
Files of any size
Send a full-length film if you like. It goes from your device to theirs with no size limit, and on Windows nothing is copied first. Keep EchoIt open until they have it.
You decide who reaches you
People add you with a ticket you share. They can't message you until you accept, and blocking or removing someone happens on your device only.

No sign-up. These are the screens you will see.
-
1
Install and open it
Read the short version of the terms, or the full ones, and agree.

Write down twelve words
They are your identity. Keep them on paper, somewhere safe — they are the only way back in on a new device.
-
3
Share your ticket
Pick a name, then send your connection ticket to a friend however you like.
-
4
Accept, and start talking
When they add it, you see their request with their name. Accept, and you are connected.
How it works: built on Dicsussion
Underneath EchoIt is Dicsussion, a messaging engine made by the same developer and published openly, so anyone can check how the important parts work. You never see it — it's what happens when you tap Send.
1
Your identity is made on your device
Dicsussion turns your twelve-word recovery phrase into the keys that prove who you are. They are kept on your device and never sent anywhere.
2
Every message is sealed for one person
It is locked on your device so that only your friend's device can open it, and checked when it arrives, so a changed message would not be accepted.
3
Devices are introduced, then talk directly
A connection helper introduces your device to your friend's. Usually the messages then go straight between the two. When they can't, the helper passes them along — still sealed, so it can't read them.
4
Your chats live with you
Each device keeps its own history. A message waits on your device until your friend's is reachable, then arrives — there is no server in between holding it.
Open for anyone to read. Dicsussion's code is public under the Apache 2.0 licence, on GitHub, and it lists its own known limits there. It has not had an independent security audit yet; when it has, we will say so here. The EchoIt app itself is not open source.
Questions, answered plainly
Is EchoIt free?
Yes. There are no ads and nothing to pay. It is a beta, so expect the odd bug — and tell us when you find one.
Does my friend need EchoIt open to get my message?
Messages arrive while EchoIt is in use on your phone; otherwise the next time both phones are. Until then your message waits on your device, marked as not yet delivered. There is no server holding it in between.
Can you read my messages?
No. Every message is sealed on your device and opened only on your friend's. We have no copy, and neither does the connection helper.
What happens if I lose my phone?
Your twelve-word recovery phrase brings back who you are on a new device. Your message history does not come back: there is no copy anywhere else. Keep the words safe.
Who runs the connection helper?
Number 0, the company behind the networking software EchoIt uses — until mid-November 2026 it is our own. It sees your device's internet address and when it is online, never what you write. The Privacy Policy has the details, and you can use your own helper in Settings.
Windows warns me before installing. Is that normal?
Yes, for now. The Windows installer is not yet signed with a paid certificate, so Windows may say it "protected your PC". Choose More info and then Run anyway. Only download EchoIt from this website or its release page.
Why do I have to allow "unknown sources" on Android?
EchoIt is not on the Play Store yet, so Android asks before installing an app from a website. The app is signed, so later updates install over the top and keep your messages.
Can I make group chats?
Not yet — EchoIt is one-to-one for now.
Is EchoIt open source?
Its engine, Dicsussion, is: anyone can read it on GitHub. The EchoIt app itself is not.
How do I reach the developer?
Message me on Telegram (@quazarLover) or Discord, follow @echo.1t on Instagram, or email wforsarthi@gmail.com.
You're early. Help shape it.
EchoIt is a beta, and the people using it now decide what it becomes. If something breaks, confuses you, or you wish it did something it doesn't, message me — every report is read. You can also report a problem on GitHub.
If a message or file didn't arrive, say whether both apps were open at the time — that one detail helps most.
What's new in 0.7
- Photos and videos show a preview before you download them.
- On Windows, files are sent from where they are — nothing is copied first.
- Long-press (or right-click) to reply, forward, copy or delete.
- Remove a contact; unread chats show on the app icon.
- A video with sound EchoIt can't play offers another player.
