AppsFlyer

What it does

AppsFlyer is a Mobile Measurement Partner (MMP) that attributes app installs and in-app events back to the ad campaigns, channels, and creatives that drove them, using privacy-compliant methods that work within Apple's SKAdNetwork and Google's Privacy Sandbox constraints. It also handles deep linking (sending users to the right in-app screen from an ad or link) and offers fraud detection to filter out fake installs before they pollute campaign data. The free "Zero" plan covers up to 12,000 lifetime installs with core attribution and deep linking features, letting early-stage apps get real attribution data before paying anything. Paid tiers move to per-conversion pricing, then to custom enterprise contracts.
