✈️Works in TestFlight

🧪Test and production data kept separate

You launched. 800 downloads. No idea where a single one came from.

App Store attribution is a black box. You're spending money on ads, posting on social, doing press outreach - and your only signal is the total download count. You can't double down on what's working because you don't know what's working.

💸Adjust / AppsFlyer

Starts at $2,000+/year. Built for million-download apps with dedicated growth teams.

🔥Firebase Analytics

Download source attribution requires ATT consent. 60%+ of iOS users deny it. Your data is missing.

🤷Guessing

Most indie developers attribute their best launch day to "the Reddit post probably" - and never find out if they're right.

Attribr gives every MRVL app accurate install attribution from day one - without ATT, without enterprise pricing.

Full-stack attribution, not just installs

Deep links, ad network postbacks, SKAN, data confidence, A/B experiments, cohort LTV, and traffic-quality signals - all in one dashboard.

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.

⚡ Up and running in 5 minutes

No onboarding call. No AASA files. No AppDelegate hooks.

Pricing questions

What counts as an install?

One unique device, once. Attribr uses a privacy-safe SHA-256 hash of the device identifier so reinstalls are detected and not double-counted. You never pay for the same user twice.

Can I stay on the free tier forever?

Yes. The Free tier is not a trial - it never expires. 1,000 attributed installs per month, one app, no credit card required. Ever.

What happens if I exceed my limit?

We warn you at 80% and again at 100%. Events above the limit are queued and held for 30 days. Upgrade within that window and all queued events process immediately. If you don't upgrade, queued events expire.

Can I switch tiers mid-month?

Upgrades take effect immediately and are prorated to the day. Downgrades take effect at the start of the next billing cycle - you keep your current tier until then.

Do you offer annual discounts?

Yes - annual billing saves approximately 16% (2 months free). You can switch from monthly to annual at any time from the dashboard.

Is there a contract or lock-in?

Never. Monthly plans cancel at end of the month. Annual plans can be cancelled with a prorated refund for unused months. No exit fees, no exit paperwork.

🐶 We eat our own dog food

MRVL runs on Attribr.
Built and used across our own app portfolio.

We built Attribr because we needed it ourselves. New apps in the MRVL portfolio ship 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.

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.

Frequently asked questions

Everything you need to know before adding the SDK.

Does Attribr require ATT (App Tracking Transparency) permission?⌄

No - Attribr uses a privacy-first approach that doesn't require ATT permission. It works on iOS 14.5+ without asking users for tracking consent.

How do I install the SDK?⌄

iOS: add the Swift package in Xcode (3 lines of code). Android: add the Kotlin dependency (3 lines). React Native/Expo: npm install @mrvltechnologies/attribr-react-native. Full setup takes under 10 minutes.

What install sources does Attribr track?⌄

App Store organic search, App Store browse, direct links, web referrals, social media, and custom deep links. Any source you can add a parameter to, Attribr can attribute.

Is my data shared with anyone?⌄

No. Your attribution data is isolated by account and protected with database-level row-level security, so no other customer can query it - not another customer, not a competitor, no one. We never sell or share it with third parties.

Does it work with Expo / React Native apps?⌄

Yes - there's a dedicated public package, @mrvltechnologies/attribr-react-native (MIT licensed, on npm and GitHub), no native module required. Validated across MRVL's own React Native/Expo apps. For any other framework, use the REST API directly.

How is the 30-day retention calculated?⌄

Attribr tracks each install as a cohort and measures how many users from that cohort are still active at day 1, 7, and 30. No sampling - every install is tracked.

Free forever. No credit card.

Start tracking installs
in the next 5 minutes.

Free tier, no expiry. Add Attribr to your next build and know where every user came from - before your next release.
