Jack Dorsey’s Bitchat: How the New Messaging App Works

Learn how Jack Dorsey’s Bitchat app works! Know about its Bluetooth messaging, privacy features, and why it’s great for offline chats.

Bitchat is a new messaging app from Jack Dorsey, the guy who co-founded Twitter and runs Block. Launched in July 2025, Bitchat is pretty cool because it works without internet. It uses Bluetooth to send messages to people nearby.

Imagine you’re at a concert, in a remote spot, or during an internet outage—Bitchat keeps you chatting. It’s all about privacy and keeping things simple, which fits Dorsey’s style of giving users control.

In this article, we’ll explain how Bitchat works, what it offers, and why it’s a big deal. Ready to check it out?

What Makes Bitchat Special?

So, what’s Bitchat all about? It’s a messaging app that doesn’t need Wi-Fi or data. Unlike apps like WhatsApp, which use servers, Bitchat lets your phone talk directly to others nearby using Bluetooth.

You don’t need to sign up with personal info. No email, no phone number—just pick a nickname and go. Messages disappear unless you save them, so your privacy stays safe. This vibe comes from Dorsey’s other projects, like Bluesky, where users call the shots.

Bitchat feels like a simpler version of old chat rooms. You can join group chats or send private messages with easy commands. It’s open-source, meaning anyone can check or change the code.

Why’s that cool? It’s great for places where regular apps don’t work, like protests or rural areas. Let’s see how it pulls this off.

How Does Bitchat’s Bluetooth Trick Work?

Okay, how does Bitchat let you chat without internet? It uses something called a Bluetooth Low Energy (BLE) mesh network. Let’s break it down simply.

The Magic of BLE Mesh

Picture yourself at a packed festival with no signal. You want to text your friend across the crowd. Bitchat uses Bluetooth to connect your phone to others nearby.

Each phone passes your message along, like a relay race, going beyond Bluetooth’s usual 30-100 meter range.

Here’s how it goes:

• Finding Friends: Your phone spots other Bitchat users nearby.
• Passing Messages: If your friend’s far away, your message hops through other phones.
• Holding Messages: If they’re offline, nearby phones save the message until they’re back.

If one phone drops out, the message finds another way. Pretty smart, right? But how far can it go?

Reaching Farther

Bluetooth usually works up to 100 meters. Bitchat’s mesh can push it to 300 meters or more, says Dorsey. Special phones act as “bridges” to connect different groups, so messages travel further.

At a big event, your message could hop through lots of phones to reach someone across a field.

Dorsey’s team is also planning to add WiFi Direct. That’d make messages faster and let you send bigger files, like photos. Bluetooth is great for text, but WiFi could make Bitchat even better.

Check out this quick comparison:

Feature	Bluetooth (BLE)	WiFi Direct (Planned)
Range	100-300 meters	Up to 200 meters
Power Use	Low	A bit more
Speed	Okay for text	Better for files
Best For	Simple chats	Photos, bigger messages

Now you know the tech, let’s talk about keeping your messages safe.

Is Bitchat Safe to Use?

You’re probably wondering if Bitchat keeps your chats private, especially in tricky situations like protests. Let’s look at how it protects you and any risks to watch for.

Keeping Your Chats Private

Bitchat uses strong security to lock down your messages. Here’s what it does:

• Super-Strong Encryption: Private messages are locked so only your friend can read them.
• Group Chat Locks: Group chats have their own security to keep them safe.
• Message Checks: Bitchat makes sure no one messes with your messages.
• Fresh Keys: It creates new security codes each time you chat, so old messages stay safe.
• Fake Messages: It sends dummy messages to hide your real ones from snoopers.
• Quick Delete: Triple-tap the app’s logo to erase everything fast.

Messages stay on your phone and vanish when you close the app. You can save group chats if you want, but private ones disappear unless you say otherwise.

No servers, no tracking—just you and your chat. Sounds good, right? But there are some things to be careful about.

Things to Watch Out For

Bitchat’s privacy game is strong, but it’s not perfect. Dorsey said on GitHub that nobody’s fully checked the app for weak spots yet.

A researcher named Alex Radocea found a problem where someone could pretend to be your friend by stealing their code. There’s also a chance hackers could sneak into your phone through a bug.

Dorsey’s working on fixes and asking for help to spot issues. For now, experts say don’t use Bitchat for super-important stuff until it’s safer.

For casual chats, it’s probably okay, but be careful if it’s sensitive. Want to try it? Here’s how to start.

How to Use Bitchat

Bitchat’s easy to set up and use. Let’s walk through getting it ready and how to chat.

Setting It Up

You can get Bitchat on iOS (16.0+), macOS (13.0+), or Android (APK v1.1.6). The iOS beta filled up fast, but it’s now on the App Store.

Android users can download it straight from Bitchat’s website.

Here’s what to do:

1. Download It: Grab the app from the App Store or Bitchat’s website for Android.
2. Pick a Nickname: Open the app, choose a name, or use the one it gives you. No personal info needed.
3. Connect: Your phone links to nearby Bitchat users automatically.

Chatting with Bitchat

The app feels like a simple chat room. You can join group chats with hashtags (like #party) or send private messages.

Here are some handy commands:

• /j #channel: Join or start a group chat.
• /m @name message: Send a private message.
• /channels: See what group chats are around.
• /pass [password]: Lock your group chat.
• /block @name: Stop someone from messaging you.

You can tag people easily with @mentions. If someone’s offline, their messages wait until they’re back. Tech fans can even build Bitchat themselves from its open-source code on GitHub.

So, where would you use this app?

Where Bitchat Really Helps

Bitchat’s not just a neat idea—it’s super useful in certain situations. Let’s check out where it shines.

You can use Bitchat for:

• Protests: When the internet’s blocked, like in the 2019 Hong Kong protests, Bitchat keeps you connected.
• Disasters: If cell towers are down after a storm, aid workers can still talk.
• Remote Spots: In areas with no signal, like far-out villages, you can message locally.
• Big Events: At festivals with bad service, you can find your friends.

Unlike older apps like FireChat, which had security problems, Bitchat focuses on keeping things private. It’s not perfect yet, but it’s got big potential.
