Free App Attribution SDK for iOS and Android
Attribr is a free app attribution SDK that tracks user installs and measures campaign performance across iOS and Android platforms. It gives you the data you need to optimise acquisition without the expense of enterprise attribution platforms.
What Attribr Does
Attribr connects your app installs to marketing campaigns, helping you understand which channels and ads drive the most valuable users. The SDK integrates directly into your iOS and Android builds, then attributes each new install to its source - whether organic, paid ads, or referral. Unlike enterprise tools, Attribr keeps costs low by eliminating unnecessary complexity. You get real-time install data, campaign performance metrics, and user journey insights without requiring a large engineering team to maintain custom tracking logic.
iOS and Android Support
Attribr's SDK works natively on both platforms with consistent measurement. On iOS, it respects Apple's app tracking transparency (ATT) framework and adapts to iOS 14+ privacy changes. Android implementation leverages Google Play services and supports both Google Advertising ID and custom identifiers. The SDK is lightweight, adds minimal overhead to your app bundle, and requires only a few lines of code to initialise. Both platforms receive the same rich event data, so you can compare campaign performance across your entire user base.
How Attribution Works
When a user installs your app after clicking an ad or visiting a link, Attribr's SDK captures device signals, timing, and referrer data. This information is matched against your campaigns to determine attribution. The system supports multiple attribution models - last-click, first-touch, or data-driven - so you can measure what matters to your business. Real-time dashboards show install volume, cost per install, retention by source, and cohort analysis. You can then feed this data back into your ad platforms to optimise future campaigns.
No Hidden Fees
Attribr's free tier removes the barrier to entry for startups and small teams. You can track unlimited installs and campaigns at no cost. There's no setup fee, no per-install charge, and no surprise billing. As your app scales, transparent pricing options exist, but the SDK itself and core attribution features remain accessible to everyone. This approach means you can validate your user acquisition strategy before committing to an enterprise platform.
Quick Integration
Installing the Attribr SDK takes minutes. For iOS, add the pod dependency, initialise in your app delegate, and log key events like registration or purchase. Android follows the same pattern with Gradle dependency and initialisation in your main activity. Documentation covers both native implementations and cross-platform frameworks like React Native and Flutter. Once live, the SDK runs in the background and requires no ongoing maintenance, freeing your team to focus on product and growth.

Whether you're launching your first app or scaling an established one, free attribution data gives you the competitive edge to spend smarter on user acquisition.
