Apple details two ad measurements technologies that advertisers can use without tracking users, ahead of imminent rollout of App Tracking Transparency feature
Starting with iOS 14.5, iPadOS 14.5, and tvOS 14.5, Apple will be requiring apps to receive a user's permission to track …
Context & Ripple Effects
The ATT prompt has been sliding toward launch since late 2020, when Apple's privacy dialog began appearing for some iOS 14 users ahead of schedule, and January's announcement set an early-spring debut. With the release imminent, Apple is now handing advertisers a replacement path so measurement doesn't die with the IDFA.
The asymmetry is the story: as Forbes reported, Apple Advertising stays on by default in iOS 14 while every other ad network must ask permission — and the two tracking-free measurement technologies are what third parties get in exchange.
First-order effects
- Ad networks and app developers must either rebuild attribution on Apple's tracking-free measurement stack or accept degraded targeting once the ATT prompt ships with iOS/iPadOS/tvOS 14.5.
- Apple sets the compliance clock itself: all iPhone, iPad, and Watch app submissions must follow ATT rules from April 26, making adoption mandatory rather than optional for new App Store releases.
Second-order effects
- Facebook, Snap, Twitter, and YouTube — whose ad products depend on cross-app identity — face forced measurement overhauls; the eventual bill was estimated at almost $10B in combined lost ad revenue across just the second half of 2021.
- Advertisers redirect budget toward channels where consent isn't required, including Apple's own search ads — which Apple later expanded further by rolling out more ads in App Store search results.
Third-order effects
- Measurement consolidates around platform-operated, privacy-laundered APIs, giving OS owners both the rulebook and a fast-growing first-party ad business — a pattern Apple extended when it explored ad-tracking options for Apple TV+ with UK ratings body Barb.
- If permission-based defaults become the norm, ad economics bifurcate into consent-rich walled gardens and consent-starved open web, with the platform collecting rent from both sides.
The trend: Platform owners are converting privacy regulation into a competitive moat, writing the measurement rules their own advertising arms are best positioned to win under.
