Go launcher is not a good apps as compare to nova launcher. I tried that go launcher but I didn't like it because its doesn't seems stylish and its a very hangy launcher. Nova launcher is far batter then other launcher because it contain very fast loding apps, go very smooth and look very cool and open any apps fast.
Go launcher application is not so convient for user as compare to nava. I always used nova launcher its dont contain any bullshit advertisement and news. I recommend you nova launcher to download its fast and mindblowing launcher
