On Android, you can uninstall an app by opening Settings, selecting "Apps," then choosing the app from the list and finally tapping "Uninstall," then "OK." You can also drag the app's icon from your home screen or app drawer and drop it on the "Uninstall" button. But if you have Nova Launcher, there's a much better way.
Just long-press the app's icon, then long-press "App Info," which has a small circle icon with an "i" in the center. When you do, you'll be asked if you want to uninstall the app. Choose "OK" and it'll be uninstalled.
You can do this with apps on your home screen or in your app drawer. But the latter is less necessary because there's already an "Uninstall" option in the popup menu when you long-press an icon in the app drawer.
