There is an option to exclude all in-app banner ads (I think). It is experimental, and called "GMob mobile app non-interstitial", and it is under "Site Category Exclusions". GMob - I think this is Google internal term for the AdMob business they bought non-interstital - I think this is a fancy word for "banner" ads. If you put it all together, excluding "GMob mobile app non-interstitial" as a Site Category, should stop your ads from running in mobile app banners. If you do this when creating a campaign, then you can still target tablets without getting killed by flappy bird on the iPad.
