Apple's App Tracking Transparency framework fundamentally changed how marketers track iOS users—and many are still struggling to adapt. With default opt-out rates hovering around 75-85% on iOS devices, the data gaps in your attribution have likely grown wider. But the right iOS tracking solution can help you recapture visibility into your customer journeys, feed better data to ad platform algorithms, and make confident optimization decisions again.

We evaluated these top solutions based on tracking accuracy, ease of implementation, ad platform integrations, and real-world performance for paid media teams. Here's what actually works in 2026.

1. Cometly

Best for: Paid media teams needing accurate attribution and AI-powered campaign optimization

Cometly is a marketing attribution platform built specifically for marketers running paid campaigns across multiple channels.

Where This Tool Shines

Cometly tackles iOS tracking limitations head-on with server-side tracking that bypasses browser-based restrictions entirely. This means you're capturing conversion data that most cookie-based solutions miss completely.

The platform's Conversion Sync feature feeds enriched, first-party data back to Meta, Google, and other ad platforms. This improves their algorithm optimization even when direct tracking is limited. Instead of guessing which campaigns work, you're giving ad platforms the conversion signals they need to optimize effectively.

Key Features

Server-Side Tracking: Captures conversion data without relying on iOS browser tracking, maintaining accuracy despite ATT restrictions.

Conversion Sync: Sends enriched conversion events back to ad platforms via Meta CAPI and Google Enhanced Conversions, improving algorithm performance.

AI-Powered Recommendations: Analyzes your attribution data to identify high-performing campaigns and suggest optimization opportunities across channels.

Multi-Touch Attribution: Tracks the complete customer journey across all marketing touchpoints, not just last-click attribution.

Real-Time Analytics: Live dashboard showing campaign performance, attribution models, and conversion paths as they happen.

Best For

Marketing teams and agencies managing significant paid advertising budgets across Meta, Google, TikTok, and other platforms. Particularly valuable if you're struggling with iOS attribution gaps affecting your optimization decisions or need to feed better data back to ad platform algorithms.

Pricing

Custom pricing based on your ad spend volume and tracking needs. Contact their team for a tailored quote.

Where This Tool Shines

AppsFlyer has invested heavily in making SKAdNetwork actually useful for marketers. Their conversion value mapping helps you extract maximum insight from Apple's privacy-preserving attribution framework, which typically provides limited granularity.

The platform's predictive analytics use machine learning to fill attribution gaps caused by iOS tracking restrictions. This gives you directional insights even when exact user-level data isn't available, helping maintain optimization velocity.

Key Features

SKAdNetwork Optimization: Advanced conversion value mapping and dashboard for managing Apple's attribution framework effectively.

Predictive Analytics: Machine learning models estimate attribution for iOS users who haven't opted into tracking.

Deep Linking Suite: Handles deferred deep links and cross-platform user journeys from ads to specific in-app content.

Free tier available for startups. Paid plans typically start around five to six cents per conversion, with custom enterprise pricing for larger volumes.

Adjust is a mobile measurement platform with particularly strong fraud prevention and conversion modeling features.

Where This Tool Shines

Adjust's conversion modeling approach helps marketers estimate the impact of campaigns even when iOS tracking data is incomplete. Rather than leaving attribution gaps empty, the platform uses probabilistic modeling to provide directional guidance for optimization.

Their fraud prevention suite operates in real time, rejecting fraudulent installs before you pay for them. This becomes especially valuable as iOS tracking restrictions make it harder to identify suspicious traffic patterns manually.

Key Features

Conversion Modeling: Probabilistic models fill iOS attribution gaps to maintain optimization insights despite tracking limitations.

Incrementality Measurement: Test whether your campaigns actually drive incremental conversions or just capture users who would have converted anyway.

Real-Time Fraud Prevention: Identifies and rejects fraudulent installs before attribution, protecting your acquisition budget.

SKAdNetwork Dashboard: Centralized view of Apple's attribution data with optimization recommendations.

Where This Tool Shines

Branch excels at tracking users who move between your website and mobile app. Their deep linking technology ensures you can follow the customer journey even when someone clicks an ad on mobile web, browses your site, then later downloads your app and converts.

The platform's unified identity resolution connects these fragmented touchpoints into coherent attribution paths. This matters increasingly as users interact with brands across multiple devices and contexts before converting.

Key Features

Singular combines mobile attribution with cost aggregation and creative analytics in a unified marketing intelligence platform.

Where This Tool Shines

Singular automatically pulls cost data from all your ad networks into one place, matching it with attribution data for true ROI analysis. This eliminates the spreadsheet gymnastics most teams do to understand actual campaign profitability.

Their creative analytics go deeper than most platforms, showing performance at the individual asset level. You can see which specific images, videos, or ad copy variations drive the best results across networks, making creative optimization far more precise.

Where This Tool Shines

9. Mixpanel

Best for: Product analytics with iOS event tracking for behavioral analysis

Mixpanel is a product analytics platform offering iOS event tracking focused on understanding user behavior patterns.

The platform's self-serve implementation makes it accessible for smaller teams without dedicated data engineering resources. You can start tracking iOS events and analyzing funnels within days rather than months.

Finding Your Best Fit

Your ideal iOS tracking solution depends heavily on your specific marketing context and technical resources.

If you're running significant paid media campaigns and need accurate attribution that feeds optimization signals back to ad platforms, Cometly's server-side tracking and Conversion Sync capabilities address the core iOS tracking challenge directly. The AI recommendations help you actually use attribution data to improve performance rather than just reporting what happened.

For mobile-first apps at enterprise scale, AppsFlyer and Adjust offer robust SKAdNetwork optimization and fraud prevention that become essential as acquisition budgets grow. Branch makes sense when your customer journeys span web and app touchpoints that need unified measurement.

Building long-term first-party data infrastructure? Segment or mParticle provide the foundation for owning your customer data and routing it wherever needed. These platforms solve a broader problem than just iOS tracking, but they're increasingly necessary as third-party tracking continues degrading.

The reality is that iOS tracking will keep getting harder. Apple has shown no signs of loosening privacy restrictions, and other platforms are following their lead. The solutions that work in 2026 focus on first-party data collection, server-side tracking, and feeding enriched conversion signals back to ad platforms despite tracking limitations.
