A simple app to preview 16 day forecast and:

  • Show a list of weather forecast
  • Shows weather details.
  • Shows settings view to change from Centigrade to Fahrenheit and vice versa.
  • Offline/Local storage using Realm Framework.
  • Local Notifications to show weather alert in each morning and night.

I am using the 16 Day Weather Forecast of this API.[api-key]&days=[days]&lat=[latitude]&lon=[longitude]&units=M sample-key To test this API,
For testAPI I used

  • latitude and longitude for current user location
  • 16 for days
  • a specified api-key e9d258e0555142618aabc4f395b62dce
