On iOS, Apple decides what an attribution tool can see. Knowing three terms is enough to judge any provider.
Start here
- Best app attribution on iOS: what Apple's rules allow What Apple's ATT, SKAdNetwork 4 and AdAttributionKit mean for app attribution, and what to ask an attribution provider about them.
Guides
- App Tracking Transparency: what the prompt controls What Apple's App Tracking Transparency prompt allows and blocks, what counts as tracking, and which parts of app attribution work without consent.
- SKAdNetwork postbacks and their three windows How SKAdNetwork 4 postbacks work: three conversion windows (days 0-2, 3-7, 8-35), random delays of 24-48 and 24-144 hours, and what each one carries.
- Fine and coarse conversion values What fine-grained and coarse conversion values are, which SKAdNetwork postback carries each one, and how a small team should decide what the values mean.
- AdAttributionKit and how it relates to SKAdNetwork AdAttributionKit is Apple's newer ad attribution framework. What it adds over SKAdNetwork, how the two work together, and what an app team should do.
- What you can still measure without the IDFA Five things you can still measure on iOS without the IDFA: framework installs, early quality, later rough-level activity, consented users and first-party data.
- How iOS and Android attribution differ iOS attribution runs on consent plus Apple's delayed, campaign-level frameworks. Android has the Play Install Referrer. How that changes your reports.
