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.

This is great. Is there a version of this that does p2p off-grid messaging? Use cases from: 1. Coordination between group members during camping in the wilderness. A mesh solution that works across iOS and Android would be ideal but mesh isn't a hard requirement either. 2. Messaging within a group who's flying together but across different seats/sections at cruising altitude in a long haul flight.

Not right now. There are applications out there that do p2p off-grid messaging.

Some of them might require you open the application the first time ever while on internet.

There are many out there (on the App/Play store) that support both use cases you mentioned, I just can't list any off the top of my head because it's been a while since I used one.
