Apple’s App Tracking Transparency Reshapes Advertising Landscape
Apple’s App Tracking Transparency (ATT), launched with iOS 14 adn enforced in April 2021, has dramatically altered the digital advertising ecosystem. The feature requires apps to obtain explicit user permission before tracking their activity across other apps, impacting how advertisers target and measure campaigns.
Research indicates a significant drop in cross-app tracking since ATT’s implementation. A study by frankfurt-based researchers revealed that the percentage of trackable Apple users in the U.S. plummeted from 72.63% to just 17.9%. This shift stems from both the requirement for apps to request permission and users’ ability to opt out at the system level.

The decline in trackable users has led to increased costs for advertisers targeting the remaining users and a decrease in overall advertising spending based on Apple’s Identifier for Advertisers (IDFA). Companies like Meta have experienced revenue drops as a result of these changes.
In response, advertisers are exploring alternative tracking methods, including device fingerprinting, which gathers details like screen size, OS version, and installed fonts to identify users. Apps are also focusing on contextual advertising, targeting users based on their in-app activity rather than cross-app data, and leveraging first-party data like newsletters.
Another consequence of ATT is the increase in in-app purchase prices. With targeted advertising less effective, app developers are seeking to generate more revenue from each paying user.A report indicated that single-purchase in-app purchases rose by approximately 36% year-over-year from 2021 to 2022, while subscriptions increased by about 19%.
Apple faced a fine in France following complaints from advertisers who alleged the company abused its power in implementing App Tracking Transparency.
What’s next
While not a complete end to cross-app tracking, app Tracking Transparency has significantly curbed the practice and triggered ample changes across the tech industry. Meta, such as, reportedly lost $12.8 billion in 2022 due to ATT and has as diversified its business model to focus on consumer hardware and AI.
