ATT user opt in insights from AppsFlyer

Since the rollout of Apple's App Tracking Transparency (ATT) in April 2021, the landscape of user privacy and advertising in apps has significantly evolved. As of Q1 2024, there's a noticeable increase in user opt-in rates, with 51% of gaming app users and 46% of non-gaming app users consenting to tracking, reflecting rises of 10% and 3% respectively. Alongside user behavior, developer adoption has also grown, with 84% of gaming and 68% of non-gaming app developers now incorporating the ATT prompt - a respective 16% and 14% increase in compliance. This change has been mirrored by a substantial rise in advertising expenditure on iOS platforms, seeing a 28% surge in total ad spend year-over-year, vastly outpacing Android's 5% growth. Additionally, non-organic app installs have seen a significant uptick, particularly on iOS, marking a 51% year-over-year increase, which highlights the evolving dynamics of digital marketing driven by heightened privacy measures.
