Hi everyone,
OpenAEDMap (
https://openaedmap.org/ ) allows you to find (and add!) AEDs in your area. These devices have proven themselves as life-savers in heart failure - when every second matters. The data is synced to OpenStreetMap database, so it's openly licensed (ODbL) and can also be used in other OSM-based apps. AFAIK, there is no other comparable map - they are either proprietary or show a single country.
