🏆 Unique to Attribr

Who drove your best users?

Track referral codes person-to-person. See which promoter drove which subscriber. Map installs → day-30 retention → revenue. No other MMP does this at any price.

✈️ TestFlight attribution

Works before App Store approval.

Give different referral codes to your Discord, email list, and Product Hunt. Find out which beta community gives you the most engaged testers. Branch and AppsFlyer can't do this.

Full-stack attribution, not just installs

Deep links, ad network postbacks, SKAN, A/B experiments, cohort LTV, and fraud detection — all in one dashboard.

🔗

Deep Linking

Smart links that survive install.

Universal Links + App Links + deferred deep linking. Route users to the right screen, even if they install the app first. No AASA file headaches.

📡

Ad Networks

Know which ad drove which install.

Connect Facebook, Google, TikTok, Snapchat, and Apple Search Ads. Server-to-server postbacks. No client-side SDK bloat.

🛡️

SKAN 4.0

Privacy-preserving attribution.

Full SKAdNetwork support. Configure conversion values from your dashboard. The attribution framework Apple actually endorses.

🧪

A/B ExperimentsGrowth+

Split-test your paywall in production.

Create named experiments with traffic splits. SDK assigns variants deterministically per device — no network call required. Dashboard shows conversion rates and statistical significance.

📈

Cohort LTVPro+

Know when each channel goes profitable.

Group installs by source, campaign, or country. See D1→D365 revenue curves with power-law projections. Enter your CPI and see exactly which channels have paid back.

🔎

Fraud DetectionPro+

Stop paying for fake installs.

Velocity checks, device fingerprint analysis, and behavioural signals flag suspicious install bursts in real time. Block fraud before it burns your UA budget.

AppDelegate.swift

// AppDelegate / App.init()
Attribr.initialize(apiKey: "attr_live_…")
Attribr.setConsent(.granted)

// Every time app becomes active:
Attribr.trackLaunch()

That's it. No AASA file. No URL scheme. No AppDelegate hooks. Just 3 lines.

🐶 We eat our own dog food

MRVL runs on Attribr.
All 30 of our apps.

We built Attribr because we needed it ourselves. Every app in the MRVL portfolio ships with Attribr wired in on day one — the same SDK, the same dashboard, the same pricing you're looking at right now. When we fix a bug or ship a feature, we feel it before you do.

integrated for every new build

“

We track every install, every referral, and every 30-day retention curve across the entire MRVL portfolio in one dashboard. No spreadsheets. No separate MMP contracts. No SDK bloat slowing down our apps. We genuinely would not sell something we don't run ourselves at this scale.
