Deep Linking
Deferred deep linking that survives the install
Click a link, install the app, and land on the exact screen — promo code, product, profile, anything. LinkTrail bridges the App Store handoff and resolves the deep link on first open.
The mobile linking platform
Deferred deep linking: one link from ad to install to the right in-app screen.
LinkTrail is the deep linking and attribution platform for mobile-first teams. Smart-route every click to App Store, Play Store, or web. Survive the install. Land users on the exact screen they came for — with full campaign credit and fraud-clean data.

The platform
Everything you need to ship, attribute, and grow.
LinkTrail bundles deep linking, attribution, fraud protection, and analytics into one platform — so you don't stitch together five vendors to answer "where did this install come from?"
Smart Routing
One link. Every device. The right destination.
Detect iOS, Android, and desktop in real time. Route to App Store, Play Store, mobile web, or a fallback page — all with the same shareable short link.
Attribution
Multi-signal attribution, deterministic where it counts
A waterfall of Google Play Install Referrer, deferred click tokens, and optional consent-gated IP + platform matching — no advertising identifiers. First-touch, last-touch, or linear models, configurable per workspace.
Fraud
Block click flooding and device farms automatically
Every install is scored against velocity, device-signal, and SDK-spoofing heuristics. Suspicious installs are flagged before they ever poison your funnel.
Privacy
AdAttributionKit and SKAdNetwork, first-class
Register for AdAttributionKit and SKAN, push conversion values, ingest postbacks. ATT-aware, privacy-safe, store-policy-clean.
Analytics
A real-time dashboard your growth team will actually use
Clicks, installs, attributed installs, and fraud signals — broken down by campaign, channel, platform, and link. Auto-refreshing, no waiting on cron jobs.
How it works
From tap to attributed install in four steps.
One link does the work of an ad redirector, app-store router, attribution engine, and deep-link resolver — without losing the user along the way.
- 01
Create a smart link
Define a deep link path, custom payload, and per-platform fallbacks. Generate a short link or QR code in seconds.
Dashboard → Links → Create link Domain links.yourapp.com Deep link path /promo/summer Fallback URL yourapp.com/promo Campaign summer_launch Channel instagram Custom data { "code": "SUMMER50" } - 02
Route every click intelligently
LinkTrail inspects the User-Agent, records the click with its campaign context, and redirects iOS to App Store, Android to Play, desktop to web — no extra logic on your side.
GET /l/abc123 ↳ iPhone → apps.apple.com ↳ Pixel 8 → play.google.com ↳ Mac → linktrail.io/promo - 03
Match the install to the click
Our attribution waterfall runs the Play Install Referrer, deferred click tokens, and optional consent-gated probabilistic matching — no advertising identifiers. Every install carries the match type that produced it, and clean campaign credit.
matchType: "deterministic" campaign: "summer_launch" channel: "instagram" attributed: true - 04
Land users on the right screen
On first open, the SDK fires onLink with the path and custom payload. Skip the homepage. Convert users straight into the experience they tapped on.
LinkTrail.shared?.onLink { link, _ in router.navigate(to: link.path) // → /promo/summer · code SUMMER50 }

A waterfall designed for the post-IDFA world.
LinkTrail starts with the most accurate signal available — the Play Install Referrer or a deferred click token — and only falls back to consent-gated probabilistic matching when nothing else applies, and only if you switch that on. No advertising identifiers, ever. Every install is recorded with the match type that produced it, so you know exactly what you're looking at.

Click country ≠ install country, when both are known
An install that trips a rule is flagged in your reporting with the rules that fired — ctit_too_short, not a number to interpret. "This install arrived 1.2s after its click" is an argument you can put to an ad network. What to do about a flagged install stays your call.
Click injection is checked on every install. The rules marked Advanced are part of advanced fraud prevention — see plans.
Integrations
Plays nicely with your existing growth stack.
Capture the click ids your ad networks stamp on every link, import their cost exports, and land raw clicks, installs and events in your own warehouse. Spend comes from the CSV the network exports — LinkTrail doesn't connect to your ad accounts.

Stop sending paid installs to your homepage
You paid for a tap on a specific product, then dropped the user on your home screen. A deferred deep link carries that intent through the install — here's how.

Frequently asked questions
What is deferred deep linking?
Deferred deep linking carries a link's destination through an app install. Someone taps a link without having your app, installs from the App Store or Play Store, and on first launch lands on the exact screen the link pointed to — with any custom payload intact. Universal Links and App Links alone cannot do this, because the stores don't pass context through.
Does LinkTrail work without the IDFA or Google Advertising ID?
Yes — LinkTrail never accesses the Apple IDFA, with or without App Tracking Transparency permission, and never reads the Google Advertising ID. Attribution runs on the Google Play Install Referrer, a deferred click token, and consent-gated probabilistic matching. Resetting an advertising identifier has no effect on it.
How does LinkTrail handle end-user consent?
The iOS and Android SDKs are consent-gated by default. Until your app grants consent, deep links still route to the right screen, but no attribution is recorded and events are queued. Calling setConsent(true) after your consent prompt attributes the install and flushes the queue, without re-routing a user who already landed.
Which platforms does the LinkTrail SDK support?
iOS (Swift Package Manager or CocoaPods, iOS 15+), Android (Maven Central, minSdk 26), React Native (a New Architecture TurboModule), and Flutter (a pub.dev plugin). The React Native and Flutter packages wrap the same native SDKs, so behaviour matches across all four.
Where is LinkTrail data processed?
On EU infrastructure by default — application, database, content delivery, and monitoring. Our full sub-processor list, with transfer notes, is published in Annex III of the Data Processing Agreement rather than available only on request. If you have specific data residency requirements, talk to us before you sign anything.
Is there a free plan?
Yes. The Free plan covers 5,000 monthly active users, 25,000 clicks a month, and 100 links, at no cost and with no card required. Paid plans start at $19/month for Starter and $49/month for Growth. If you hit a plan limit we throttle the affected features rather than charging overage fees.
How does LinkTrail compare to Branch, AppsFlyer, and Adjust?
LinkTrail publishes flat pricing you can self-serve and integrate the same day, where those platforms quote by monthly tracked users through a sales process. We cover the same core — deferred deep linking, smart routing, and install attribution — with an SDK that never touches advertising identifiers and consent gating on by default. Our comparison pages cover each of them in detail, including where they're the better pick.
