What is Bitchat? A Guide to Jack Dorsey’s New Messaging App
Introduction: A Messaging App Without Internet
In July 2025, Twitter co-founder Jack Dorsey introduced Bitchat, a revolutionary messaging app that lets you chat without an internet connection. Unlike WhatsApp, Telegram, or Signal, Bitchat uses Bluetooth mesh networking to send messages directly between devices — making it a powerful tool in situations where Wi-Fi or mobile data is unavailable.
How Does Bitchat Work?
Bitchat relies on Bluetooth Low Energy (BLE) mesh technology, where each device becomes a relay node to pass along encrypted messages.
Key aspects of its working:
- No Servers Needed – Messages travel device-to-device.
- Offline Coverage – Works within 300 meters or through a chain of connected devices.
- Store-and-Forward System – If the recipient is not in range, nearby devices can temporarily store and forward messages when connected.
Key Features of Bitchat
- Completely Offline – Works without Wi-Fi or mobile data.
- Privacy-First Design – No account, phone number, or email required.
- End-to-End Encryption – Uses Curve25519 & AES-GCM encryption standards.
- Password-Protected Channels – Allows private group messaging.
- Panic Mode – Triple tap to instantly erase all chats.
- Open Source – Code is available on GitHub for public review.
Use Cases: When Bitchat is Most Useful
- Natural Disasters – Communicate during power and internet outages.
- Protests & Restricted Zones – Stay connected without fear of surveillance.
- Remote Areas – Ideal for trekking, camping, or rural locations.
- Crowded Events – Works when mobile networks are overloaded.
Availability
- iOS – Available via Apple’s TestFlight and now on the App Store.
- Android – APK available via the official GitHub page.
- Beta Limitations – Currently supports a limited number of users in early testing.
Limitations & Security Concerns
- Range is limited by Bluetooth (~300 meters).
- No external security audit yet, so vulnerabilities may exist.
- Impersonation is possible if usernames are not verified.
Conclusion
Bitchat is not just another chat app — it’s a privacy-focused, internet-independent communication tool designed for resilience. Whether you’re facing a blackout, traveling in remote areas, or just want more control over your data, Bitchat offers a glimpse into the future of decentralized messaging.
