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 of course depends on the disaster, but in case of war this app can be used to find survivors for purposes other than saving them.
Great idea though.
It'll be easy to find a collapsed building site. The person rescuing just needs to be close to the site with the app. Otherwise, the signal might not be noticed.
+1 regarding finding survivors for malicious purposes. I tried my best to lower the surface area of that happening. It's still possible in edge cases, like opposing soldiers finding the people transmitting SOS, but they need to be extremely close to do that.
