Tap “Find shelters near me”, or pick a spot on the map.
Offline use
1. Shelters. Download every shelter in Sweden so “nearest” search works
anywhere with no signal. The data is small.
All shelters not downloaded yet.
2. Map picture (optional). Save the map for an area
(Home, Work…) so you also see it offline. Move the map so the crosshair (✛) marks the centre,
pick a radius, name it, then download.
