Attribr is a lightweight mobile attribution and analytics SDK built for indie developers and small teams managing multiple apps. Drop in 3 lines of code — that's the entire integration. **What it does:** - Tracks installs, 1-day / 7-day / 30-day retention automatically - Probabilistic deferred deep linking on both iOS and Android (no IDFA required) - Play Install Referrer integration for deterministic Android attribution - Real-time cohort analysis, LTV tracking, and fraud detection in the dashboard - SKAN 4.0 support for iOS privacy-preserving attribution - Webhooks for piping install/retention events to your own stack - Smart banners, custom deep links, and referral attribution built in **Why builders use it:** Most attribution tools are built for large teams with large budgets. Attribr is the opposite — it's designed for developers who ship multiple apps and need to know which channels and campaigns are actually driving installs, without a complex setup or a per-MAU bill that scales against you.
