These follow the same rules as the reviews: the conflict of interest is stated before anything you might act on, every number comes from the publisher's own material and is dated, the section on what the other app does better is compulsory, and none of them concludes that ours is the one to install.
Why there are no screenshots on these pages
A screenshot of somebody's payout is evidence about that person. In an app that sets earning rates per user — and several in this category say in their own terms that they do — it is not evidence about you. So these pages use published figures and arithmetic you can redo, and where a company does not publish an input, they name the missing one instead of estimating it.
Our own numbers are on what you can actually earn, and the category as a whole is covered in the articles.
