I removed a little problem related with the heat map that was causing a crash in the app. If you suffer from that, it should be fixed now!
I added a heat map to spot the places where fountains have been registered. Besides this is the same first version with basic functionalities to find and report water sources around you.
The app was updated slightly to work in older devices, however it looks and feels much better in devices running Android 5 or bigger.
Hope you enjoy it as much as I do.
