One correction: on the app, what you lose by never upgrading isn't what people assume.
Most comparisons of the app skip whether the sorting can be trusted, which is the part that matters.
My first week on made money looked promising; by the second I was only really watching how quickly you can narrow a list down.
Provided whether the sorting can be trusted holds up, the room is a reasonable place to start.
Someone in another thread pointed me at luvdate.site and it was a fair shout.
