Publishers offering "Native In App Ad" spots

A native in-app ad is a sponsored unit that takes the look of the app around it, such as a card in a feed or a row in a list. Publishers like FotMob and Pubfinity run these inside their apps, and a few also run them on their mobile web pages.

How it's sold: Most publishers sell it through their sales team or an ad network, and some let you book it self-serve. Ten publishers list it, from custom native units to a featured slot in a timeline feed.
What it costs: Most publishers quote this on request, usually per thousand impressions or per click.
What you supply: You supply a headline, a short line of copy, a square or landscape image and a link to your app or page.
Best for: It suits you if you want app users to notice your message without it feeling like an interruption.
Before you buy: Ask the publisher to show you a live example, because the unit takes on the app's own styling and each app does it differently.
