Scared!!!!

I accidentally enabled notifications (but I was too lazy to disable them) and it got on my nerves so much I deleted the app altogether. Later an app suggested Talking Tom as a ad which was weird. I clicked on it and the usual download button said OPEN. It opened the app but when I went back to the App Store later it said download. ?????
