Did you know that the YouTube app can tell you how much time you spent watching videos? If you're like me, you'll be surprised how much time of your life is spent in the popular app. You can specify exactly how much you spend on YouTube.
The average person spends nearly four hours a day watching television, almost three hours a day using a cell phone, and together we watch more than a billion hours on YouTube. You can find out how much you contribute to a billion hours by looking at your iPhone or Android device's profile icon at the top right of the home screen (possibly your first initial inside a circle). On the Account screen, press the Timeout button. Now you'll get a breakdown of the time you viewed YouTube.
There are some limitations here. First, you will not receive any information if you have not turned on YouTube Watch History. Unfortunately, no long-term YouTube data is provided, just the last week's data. You can extrapolate the observed time by multiplying the weekly value.
The data is based on your watching history on YouTube and YouTube TV. So, if you subscribe to Google's streaming cable service, you'll have a higher number here. If you are viewing something in Incognito mode, if you delete something from your observation log or if you are viewing something in another account, it will not count towards your observation time.
