Introduction

LinkTrail is a mobile attribution and deferred deep linking platform. You create smart links in the dashboard, and the SDKs — iOS, Android, React Native, and Flutter — route users to the right screen in your app, even when the app wasn't installed when they tapped the link.

How a link flows

user taps https://yourapp.linktrail.io/summer-promo
        │
        ├─ app installed →  opens app → SDK delivers path + customData → your router
        │
        └─ not installed →  store page → user installs → first launch:
                            SDK matches the click → delivers the SAME link (deferred)

What you get

• Deferred deep linking — context survives the install gap, so a fresh install lands on the right screen.
• Smart routing — one link resolves to iOS, Android, or web based on the device that opened it.
• Multi-signal attribution — deterministic and probabilistic matching, with the result attached to every install.
• Hosted domain files — LinkTrail generates and serves the AASA and assetlinks.json for your link domains.
