A couple of months ago, I built this app to help identify people stuck under rubble.

First responders have awesome tools. But in tough situations, even common folks need to help.

After what happened in Myanmar, we need something like this that works properly.

It has only been tested in controlled environments. It can also be improved; I know BLE is not _that_ effective under rubble.

If you have any feedback or can contribute, don't hold back.

The EU is mandating Apple to implement WiFi-Direct https://www.ditto.com/blog/cross-platform-p2p-wi-fi-how-the-...

WiFi doesn't fare any better than BLE under rubble unfortunately, but WiFi is going to be a useful technology to build disaster response tools in general

That's awesome. We really need something stable and cross platform.

I'm not a fan of how Apple managed to make background BLE advertising and scanning work only with its own devices.
