Attribr by MRVL Use Cases: Where Install Attribution Solves Real Problems
Attribr by MRVL answers three core questions for indie developers: where each install came from, whether users stay active at day 7/14/30, and which Rippl promoter drove performance installs. It's built for small studios and solo developers who need attribution data without the enterprise price tag of Branch or AppsFlyer.
Understanding What Attribr Does
Attribr is an install-attribution SDK for iOS and Android that sits at the heart of app growth for indie developers. When you integrate the 50KB SDK into your app (three lines of code in Swift or Kotlin), it tracks every install, attributes it to a source (organic, paid campaign, word-of-mouth), and measures retention across day 7, 14, and 30 cohorts. Unlike probabilistic-only fingerprinting services, Attribr combines deterministic matching (when ATT permission is granted) and probabilistic matching (when it isn't) to work reliably on iOS 14.5+ without blocking users on privacy dialogs. Launch overhead is sub-50ms, and there are zero third-party dependencies, so your app starts fast and stays lean.
Indie Developer Growth Without Enterprise Costs
The most common use case for Attribr is indie developers who've outgrown organic discovery but can't justify the £200+ monthly cost of traditional attribution platforms. Attribr's Free tier tracks 1,000 installs per month at no cost, which covers many early-stage games, productivity apps, and utility tools. The Growth plan (£29/mo) unlocks 25,000 installs and multi-source attribution; the Pro tier (£99/mo) adds fraud signals, ad-network roll-ups, and brings-your-own integration support. This pricing structure lets you scale from solo side project to 100,000 monthly installs per app without renegotiating a contract or adding complexity.
Measuring Retention and Cohort Quality
Retention tracking is where Attribr separates signal from noise. When you run paid campaigns or partner with influencers, the install count alone lies; what matters is whether those users come back. Attribr's dashboard splits your installs by source and shows you day-7, day-14, and day-30 retention, so you see immediately which channels bring sticky users and which bring one-off installs. A studio running iOS and Android simultaneously can see that TikTok ads drive volume but low retention, while App Store feature placement drives fewer installs but higher day-30 cohorts. That insight lets you reallocate budget before the month ends.
Direct Integration with Rippl Community Marketing
Attribr has a unique feature: a direct bridge to Rippl, MRVL's community-driven performance-marketing platform. When you run a CPI (cost per install) campaign through Rippl, each install is automatically tagged with the promoter who drove it. Attribr surfaces this data in your dashboard, so you can see which Rippl creators deliver the best ROI and retention. This closes the loop between community marketing and app health in one dashboard, which no other indie-scale attribution SDK offers. If you're running Rippl campaigns, Attribr is purpose-built to measure their impact.
Small Teams Running Multiple Ad Networks
Once an app is scaling, teams often test Facebook, Google, TikTok, and Apple Search Ads in parallel. Attribr's Pro tier includes ad-network roll-up, which aggregates install and retention data across your ad accounts and displays unified cohort + funnel + retention charts in one place. You don't need to log into five dashboards to see which network is working. For small studios with two or three people managing growth, this consolidation cuts hours of manual reporting. The dashboard also flags fraud signals (suspicious install patterns, geographic mismatches) so you can spot and pause campaigns before wasting budget on invalid traffic.
Getting Started: Three-Line Integration
The reason indie developers choose Attribr over self-built solutions is speed. Integration takes minutes: add the SDK via CocoaPods (iOS) or Gradle (Android), call one initialization method in your app launch code, and pass one confirmation event when a user completes your first meaningful action (sign-up, purchase, level complete). That's it. No event mapping, no third-party trackers to juggle, no consent dialogs for Attribr itself. Within hours, installs and retention cohorts start flowing into your dashboard. As of June 2026, Attribr powers attribution for indie studios across the UK and beyond, from solo developers to teams of up to 50 people.
Start tracking installs and retention in minutes. Attribr is free for up to 1,000 monthly installs.
Frequently asked questions
Do I need ATT permission for Attribr to work?
No. Attribr uses deterministic matching when ATT permission is granted, and falls back to probabilistic matching when it isn't. Either way, you get install attribution on iOS 14.5+ without blocking users on privacy prompts.
How does Attribr compare to AppsFlyer or Branch?
Attribr is purpose-built for indie developers and small studios scaling up to 100,000 monthly installs. AppsFlyer and Branch are enterprise platforms with features (multi-app SDKs, deep linking at scale, white-label APIs) and pricing that target larger teams. If you're solo or a team under 10 people, Attribr's simplicity and cost win. If you're running 50 apps across three continents, they're the right choice.
What is the Rippl CPI promoter bridge?
Attribr integrates directly with Rippl, MRVL's community performance-marketing platform. Every install from a Rippl promoter is automatically tagged and tracked in Attribr, so you see exact ROI and retention by creator without manual matching.
How much data does the SDK add to my app?
The Attribr SDK is 50KB and has zero third-party dependencies. Launch overhead is sub-50ms, so your app start time and install size stay lean.
Can I use Attribr with my own ad networks?
Yes. The Pro tier (£99/mo) includes bring-your-own ad-network integration. You can connect custom campaign URLs or API keys, and Attribr rolls all attribution data into one dashboard.
Is there a free tier?
Yes. Attribr Free tracks up to 1,000 installs per month at no cost, with install-source attribution and basic retention cohorts. Growth and Pro tiers unlock higher volumes and advanced features like fraud detection and ad-network roll-up.
