Google has added a feature to AdWords which enables the tracking of iOS app downloads driven by in-app display ads.
Previously, it was only possible to measure Android app downloads within AdWords, which requried no code, but by adding a snippet of code to their app, iOS apps can be tracked too. 
“Apps are a powerful way to keep your most loyal users engaged, and can also be a real driver of revenue for marketers big and small. When advertising apps, the key is to know what’s working and what’s not,” said Google product manager Morgan Hallmon in a blog post. “With iOS conversion tracking, marketers can better understand which campaigns are most effective at driving app downloads. These enhanced insights help marketers iterate on app promotion strategies to reach their return on investment goals, with the help of features like the Conversion Optimizer for apps.”
