Hi, do you mean the insight feature of the parental control function? You may share some screenshots for better understanding.

@Marvin_S 

Hi. I mean the 'Family' function in the Parental Controls section of the Tether app. See screenshots

Hi, you may click on the arrow symbol to check whether you can see time website timestamps. If not, that means it does not support.

  @Marvin_S 

It doesn't show timestamps. I'm thinking though in order to calculate the total time the websites are visited, there must be timestamps recorded somewhere. The question is how to access it (not necessarily via the thether app)

I suppose that the APP was design as you see it. I would like to record your feedback first. Thanks for your cooperation~
