To GLITCHY!!!

I have installed this app twice. Right when I got the app the first time it worked then I pressed "get started" then it took me back to the home screen. I tried to get back on countless times and it still wouldnt let me on. So I deleted the app. Then I got the app again and tried to see if it would work. To make the story short, IT DIDNT!!! So I would like you guys to fix the app! Please
