One and ThreeSTUDIO

Flagship app

Retro Messenger

Messaging the way it felt before feeds. Plain text, nothing to scroll, and nobody can message you until you say yes.

01
Encrypted on your phone
Message bodies are end-to-end encrypted with Curve25519 and ChaChaPoly before they leave your phone. Your private key stays in the iOS Keychain.
02
Requests, not spam
Find people by username and send a request with a short note. A chat only opens once they accept.
03
Just text
No stickers, no reactions, no feed. One-to-one chats and groups of up to 20, in phosphor green or paper.

02The details

01

Message requests

Search a username, send a request with a short intro note, and chat once they accept. Friends can message you directly.

02

Groups up to 20

Small crews, not crowds. Group chats are end-to-end encrypted too.

03

The quiet details

Read receipts, typing indicators, search, per-chat mute, drafts, chat export, and a QR code to share your username.

04

Your keys, your passphrase

Set an optional recovery passphrase to restore your encrypted history on a new phone. We never see it.

03Questions

Good to know.

Is everything end-to-end encrypted?

Message bodies are. To show your inbox and notifications, a short preview of each message (about 80 characters), message-request notes and group names are stored in plaintext. The privacy policy lists exactly what we store.

What happens if I get a new phone?

Sign in with the same account, choose Restore and enter your recovery passphrase. Your keys come back and so does your history.

What if I forget my recovery passphrase?

We can't reset or recover it, by design. You can keep chatting, but older encrypted history can't be read on a new phone. Write it down somewhere safe.

Why no photos, stickers or emoji?

Because it's a messenger for words. Keeping it text-only keeps it fast, calm and small.

How do I block or report someone?

Open the menu in the chat and choose Report user or Block user. You can unblock people later from Settings.

How do I delete my account?

Settings → Security → Delete account. It removes your profile, friends, requests, key backup and one-to-one chats from our servers.

Is there an Android version?

Not yet. iPhone first, Android later.
