App: SG Weather Application
Developer: b1rDi3x's App
Genres: Nachschlagewerke, Dienst­programme

The application gets data from data.gov.sg which gets them from NEA. This is more accurate than most other apps that use satellites and generalize Singapore as a location rather than her different locations (Jurong, Pasir Ris, etc).
Weather forecasts and other information are also available.

All location-related calculations are done on the device thus, no private data is sent to any server.

Release notes:
Fix:
- WatchOS not able to get location

NOTE:
If you deleted the app on watchOS 10 and now unable to get location please reset your location permission settings 
Settings app → General → Transfer or Reset iPhone → Reset → Reset Location and Privacy
