Ctrtard just released a mobile advertiser intelligence tool inside the forum!
This tool is powered by Adbeat and will return ads found on the mobile web. (In other words, it does not cover in-app advertising).
Use the dropdown to select from Android, Android Tablets, iPhone and iPad. You’ll see the exact creatives advertisers are using, what network they’re running on and how many days the ad has been running. Right now this is limited to US traffic but we hope to add international soon.
