A messaging app whose name may make French speakers smile is currently enjoying enormous success in France. Called Bitchat, it has risen to the top spot of the most downloaded free apps in the App Store and is among the most popular communication apps on Android.
But why so much enthusiasm? Created by Jack Dorsey, co-founder of Twitter, Bitchat allows you to exchange messages without an Internet connection, without a mobile network and without even needing a phone number.
So how does this messaging work and why has there been so much talk about it in recent days?
Bitchat: messaging that works without Internet or mobile network
Launched in July 2025, chat It is a free messaging application and open sourceavailable on iOS and Android. Allows you to send messages to other users without going through the Internet or mobile operator networks. To work, it simply uses Bluetooth, a technology present in all current smartphones.
Unlike popular messaging apps like WhatsApp, Telegram or Signal, Bitchat does not require any registration. You don’t need to enter your phone number, email address or create an account. Simply install the app, choose a nickname, and activate Bluetooth to start exchanging messages with nearby users.
The app offers public and private conversations, with end-to-end encryption for private messages. It also allows you to send photos and voice messages. Location-based chat channels are available to interact with users in the same geographic area, but this functionality requires an internet connection.

As I mentioned above, Bitchat uses Bluetooth to allow smartphones to communicate with each other without an internet connection. But how do you convey messages to people further away? Well, it uses a system called Bluetooth mesh networking.
Simply put, when you send a message, it can be received directly by another smartphone located within Bluetooth range, usually a few tens of meters away. But the interesting thing is that other Bitchat users can act as broadcasters. Your message is then passed from phone to phone until it reaches its recipient. And it is thanks to this system that Bitchat can communicate far beyond the usual Bluetooth range.
Imagine, for example, that you are at a concert, a festival or in the middle of a demonstration with thousands of other people. You’ve probably already experienced this situation: the mobile network is saturated, your messages take forever to be sent or are simply not sent at all. This is partly because too many people use the same cell towers at the same time.
Well, with Bitchat this problem does not arise in the same way, since the application does not use the mobile network. Therefore, you can continue exchanging messages with the people around you, even when the antennas are saturated. Provided, of course, that they also use Bitchat and are within Bluetooth range, directly or thanks to other smartphones that serve as repeaters.
However, you should know that this system has its limits. Bitchat allows up to seven hops between devices, which can allow messages to travel several hundred feet if conditions allow. But it all depends on the number of users, their location and the obstacles. And while Bluetooth doesn’t rely on mobile antennas, it can also encounter difficulties in very dense crowds.
Why is Bitchat so successful in France?
Bitchat is not a new application and yet in recent days it has enjoyed real success in France. As I write these lines, it even occupies first place in the ranking of free applications in the Apple App Store.
But why this sudden madness? Well, a recent event could easily explain it. Do you see what I’m talking about? Yes, the demonstrations of October 17, 2026.
This day of mobilization brought together thousands of people throughout France around various demands, in particular purchasing power and study conditions. Violence also broke out on the sidelines of certain meetings. Two days later, Gabriel Attal proposed being able to temporarily block social media in areas affected by the unrest.
This proposal obviously sparked reactions, particularly on social media. Since this announcement, many Internet users have encouraged others to download Bitchat so that they can continue communicating during the upcoming protests, even if access to social media is blocked. That’s all.
