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.

It would be nice to have a button to play a loud sound. A common use case is to play it when you are under ruin and you hear rescuers close to you. If the rescuers heard a loud sound, they can locate you quicker.

I don't know the amount of battery that is necessary to do that.

The current "Send SOS" plays a loud sound from the speaker, with the SOS beacon.

To cut time, I didn't modify the volume programmatically. So the user would need to have their volume set at 100%.

This needs improvement, especially considering my phone is always muted.

Likewise, the battery usage needs better testing.
