This application is a free and ad-free online walkie talkie that allows users to send voice messages through the cloud. It also has the unique feature of being able to function as an offline walkie talkie when users are on the same Wi-Fi network, without requiring an internet connection. It supports various types of local area networks, including WiFi, WiFi-Direct, Wi-Fi hotspot, Ethernet, Bluetooth, and USB tethering. The application also supports headphones and headsets, automatically using them when connected. It even has support for hardware PTT buttons, allowing for instant voice data transmission. The audio transmission is in real-time, meaning that as soon as you start speaking, the other user can hear you. One of the convenient features of this walkie talkie app is the "Quick Reply" function, which automatically opens the app when receiving incoming messages, allowing for instant replies. It also has a "Home Networks" function, where users can configure a list of "home" WiFi networks, and the app will apply custom settings when connected to those networks. This can be useful for playing incoming messages loudly only when at home. To prevent accidental audio sending, the app has a "Slide To Talk" button. And for added security, all transmitted data are encrypted within the app, ensuring confidentiality. For more information, visit the website at https://slide2talk.app.
