Is there a good iOS app that lets you send text messages to nearby people without any internet connection?

bitchat mesh is a decentralized messaging app designed for private, text-based communication that operates independently of cellular data or Wi-Fi. By leveraging Bluetooth mesh networking, it allows users to create local chat channels with devices in proximity, making it highly effective for scenarios like camping trips, community events, or during network outages. The app supports multiple channels for organized group discussions and integrates TOR for added anonymity when accessing broader networks, though user reviews indicate that TOR connectivity can be problematic after iOS updates, sometimes limiting functionality to Bluetooth-only modes. Key features include an ad-free interface, a decentralized architecture that avoids central servers, and simple peer-to-peer setup. However, its utility is constrained by Bluetooth range limitations and potential compatibility issues with newer iOS versions, as some users report difficulties with node connections. For anyone needing a reliable tool to maintain communication in offline or low-connectivity environments, bitchat mesh provides a practical solution, albeit with occasional technical challenges that may require patience. Real-world use cases include coordination during natural disasters or secure chatting in remote locations, though the app works best when users are within close range and have compatible devices.
