Here is the use case:

People launch an app numerous times within a day but they may not use the app every day.

I want to look at people that use the app for 5 or more days within a quarter ​and classify them as my "loyal" app users.

Now, I don't have the people metric implemented so I will settle for unique visitors.

But is there a way to classify time as 5 or more days within a segment?

All of my "day" dimensions ask for a specific date...

Any thoughts or suggestions around this?  I'm all ears.

Thanks!
