لاسلكي, developed by Muhammed Essa, is a free voice messaging app that allows communication without the need for internet, cellular data, or communication towers. It is designed to be used in places where there is no means of communication, such as during natural disasters like earthquakes and floods. The app works by using radio devices, including Bluetooth and WiFi, to send voice messages between mobile devices. It automatically connects when the connection is lost and does not require a server, SIM card, IP, or infrastructure.

The app turns your Android phone or tablet into a wireless device, allowing you to talk to anyone around you who has the same app. The sound travels in real-time, and you can use the volume buttons to speak. The app is easy to use, with a simple and user-friendly interface. It is compatible with all Android devices and does not require any personal information or subscription. With the wireless app, you can transfer your audio data to the device that is connected to you. Overall, لاسلكي is a great solution for communication in the absence of a network and is perfect for emergency situations.
