There are many weather apps on the market, but few that offer the ability to change the default city. This is a great feature if you want to move to a new city or if you want to change your current city’s weather. To change the default city in an Android weather app, first open the app and sign in. Then, under “Settings”, select “Default City”. Next, select the desired city from the list of cities that appear. Finally, click on “Change Default City” to make your changes.
