These apps are known as ‘Off-the-grid’ chat messenger app that works even without internet connection or 2G, 3G, or 4G network coverage, somewhat like the Walkie-Talkie app for iOS and Android. These apps allow you to communicate with each other within a range of up to 100 – 200 meters, it works by broadcasting your encrypted data via the WiFi or Bluetooth.

If there is no direct connection between A and C, the app will bounce the message from A to B to C. In short, it is a P2P (peer to peer) software without a central server like WhatsApp, Line, WeChat and Facebook Message. Three good reasons for using ‘Off the grid’ aka Mesh Network chat. These chat apps can also be used as a walkie talkie. Works great on Android 8.0 Oreo / Android 9.0 [ Popsicle, Pancakes or Pie ] smartphones such as Samsung Galaxy, Huawei Mate, Oppo, Vivo, XiaoMi, Nokia, and also Apple’s iOS iPhone.

Which is all good, but there are three main challenges here:

  1. Others in the community need to be using the same app, which implies some discussion and agreement beforehand on which app.
  2. They (and you) need to already have it installed before it is needed.
  3. Generally, most of the apps are either Android or iOS only. iOS’s apps are particularly crippled by Apple’s OS policies.
