Creative History lets you look through the top-performing creatives from your competitors and compare them side-by-side.
Type the name of an app you're interested in and the search box automatically finds matching titles:
Press the Enter key to select the app. This will display the most recent creatives for that app. Scroll down to go backwards in time and see what ads were being run for earlier months.
To compare apps side-by-side, just click the Add button and search for another app. You can compare a maximum of four apps at once.
