It allows you to easily and freely share text and files with other devices via Wi-Fi or Bluetooth. It also offers advanced features such as intercom, video chats and real-time distance. You can use the app to chat and share with nearby devices even when there is no internet connection, or when the connection is weak.

Have you ever considered sending messages directly to others via Bluetooth or Wi-Fi instead of going all the way around the internet? Maybe you just want: - A messenger that works locally without the internet - Private chats with family in different rooms - Effectively share bulk files and images with your team members Give it a try if you're looking for an alternative to Bluetooth sharing or a local network transfer method (LAN). It's like a WiFi or Bluetooth walkie-talkie. - Why build this During the pandemic, it became clear how crucial it is to communicate, especially in emergencies. It’s frustrating when people are close by but can’t reach each other, despite today’s advanced technology. That inspired me to create an app that lets devices send messages and data directly—no accounts or internet needed—similar to old LAN messaging apps on PCs. I would love to hear how this application help your communication. Your feedback helps me continue to improve. By using this app, you agree to the Terms of Use.
