RevenueCat Funnel Analytics: Find Onboarding Leaks Before Users Reach Paywall
Revenue attribution for mobile app teams that need to know where sales actually come from
· Grometrics Team
The short version
If you are a mobile app developer selling subscriptions, in-app purchases, or paid plans, you already use RevenueCat to track revenue. But RevenueCat alone does not show you where users drop off inside your app before they ever reach a paywall. That gap costs you customers you never knew you were losing. Grometrics connects your onboarding screen flow to RevenueCat transaction data so you can see exactly which onboarding step kills your conversion and which acquisition source brings users who actually buy. This is not generic event tracking. This is source-to-revenue funnel analysis that tells you which work created paying customers and where users dropped before revenue.
- RevenueCat shows trials, purchases, renewals, and cancellations as revenue events but does not track screen-level user journeys
- Grometrics screen-level tracking captures every onboarding screen a user visits before reaching a paywall or completing a purchase
- Connect RevenueCat transactions to acquisition source to see which campaigns produce users who convert and which produce users who bounce early
- Identify specific onboarding screens where churn spikes so you can fix the leak, not guess at the problem
- First-party tracking captures conversions that ad platform pixels miss because the conversion happens inside your app, not on a landing page
Why RevenueCat Data Alone Does Not Show Onboarding Leaks
RevenueCat is built to handle the complexity of mobile app billing. It tracks Apple and Google billing, manages subscriptions, handles cancellations, and reports revenue. When a user buys a subscription, RevenueCat records the purchase, the renewal, and the refund. This makes RevenueCat the source of truth for what happened at the point of sale.
What RevenueCat does not do is track what happened before the user opened their wallet. Did they see your onboarding flow? How many screens did they pass through? Did they hit your paywall and bounce immediately? Did they convert on their first session or return three days later? RevenueCat knows the purchase. It does not know the journey that led to that purchase or the journey that ended without one.
This matters because the biggest revenue leaks happen before users ever reach a paywall. If 60 percent of your users drop on your third onboarding screen, you are losing revenue you cannot recover by optimizing your paywall. The problem is upstream. RevenueCat cannot tell you this. Grometrics can.
- RevenueCat records transaction events but not screen-level user flow
- Paywall performance depends on what happens in screens before the paywall appears
- Drop-off before purchase is invisible in RevenueCat dashboards
- Acquisition source quality cannot be judged without screen journey data
- Conversion rate at paywall is misleading without context of how many users reached it
The gap in your mobile funnel: You know how much revenue you made last month. You do not know how many users bounced on your second onboarding screen and never saw your paywall. That is where your revenue leak lives.
How Grometrics Connects Onboarding Screens to RevenueCat Transactions
Grometrics uses a lightweight SDK for iOS, Android, React Native, or Flutter to capture every screen a user visits from first launch through purchase or churn. This is not event logging for the sake of collecting data. This is first-party, server-side tracking designed to tie user journeys back to acquisition context and payment outcomes.
When a user installs your app from an Apple Search Ads campaign, Grometrics captures the install source and ties it to every subsequent screen they visit. When that user completes a trial, purchases a subscription, or cancels, Grometrics pulls that event from RevenueCat and connects it to the screen journey that preceded it. You see the complete loop: source, onboarding screens visited, paywall reach, and revenue outcome.
This connection is what separates Grometrics from generic mobile analytics. PostHog and Mixpanel can track screen events, but they do not natively tie those events to RevenueCat revenue data without custom engineering. Grometrics is built specifically for this connection. You do not need to write SQL queries or build data pipelines. You install the SDK, connect your RevenueCat API key, and the funnel data appears in your dashboard.
- SDK captures screen-level journey from first launch to purchase or exit
- RevenueCat API integration pulls trials, purchases, renewals, and cancellations as funnel steps
- Acquisition source is tied to each user journey without manual mapping
- Server-side tracking captures conversions that ad pixels miss because conversion happens inside the app
- Setup takes minutes with a lightweight tracking script
What RevenueCat provides as funnel steps: Grometrics treats RevenueCat events as funnel stages: trial started, trial converted, subscription renewed, subscription canceled, refund issued. Each of these revenue outcomes is connected to the onboarding screen path that preceded it.
Finding the Onboarding Screen That Kills Your Conversion
Once Grometrics is connected, you can build a funnel that starts at first launch and ends at RevenueCat revenue events. The funnel shows you exactly how many users reach each onboarding screen, how many proceed to the next, and how many drop off at each step. This is not guesswork. This is data that tells you precisely where your conversion funnel collapses.
For example, you might discover that 45 percent of users who start your onboarding flow drop off at the screen where you request notification permissions. The paywall is three screens further downstream. You are optimizing your paywall design while the real problem is a permission prompt that appears too early. Fixing that screen improves your conversion rate at every downstream stage, including revenue.
This level of insight only works when you can see the entire path from first install to RevenueCat transaction. If you only track revenue, you do not know why users did not reach the paywall. If you only track screen events, you do not know which users converted. Grometrics shows both in the same view.
- Funnel visualization shows drop-off at each onboarding screen before paywall
- Identify which onboarding step has highest churn and prioritize fixing it
- Compare funnel performance across acquisition sources to find highest-quality traffic
- Track whether users who see paywall convert at different rates based on which screens they visited first
- Measure impact of onboarding changes on trial-to-paid conversion over time
The revenue impact of onboarding leaks: If 1,000 users install your app per day and 40 percent drop on onboarding screen two, you are losing 400 potential customers per day before they ever see what you are selling. Finding and fixing that screen has direct revenue impact.
Tie Acquisition Source to Trial-to-Paid Conversion
Not all acquisition sources produce users who convert at the same rate. Users who come from Apple Search Ads may convert differently than users from organic search or cross-promotion. Grometrics attributes each RevenueCat transaction back to the original acquisition source so you can see which channels create real revenue, not just install volume.
This is critical because ad platforms grade their own homework. Apple Search Ads claims conversions they did not drive. Meta Ads reports purchase events from users who would have bought anyway. Grometrics connects real RevenueCat revenue to install source so you can see which campaigns actually created paying customers and which campaigns spent budget on users who dropped in onboarding.
When you combine RevenueCat revenue data with acquisition attribution and screen-level funnel data, you get a complete picture. You know which source brings users who convert, which onboarding screens those users pass through, and whether they convert to paid or churn. This is the loop that tells you where to spend your growth budget.
- Source-to-revenue attribution ties every RevenueCat transaction to install source
- Compare conversion rates across Apple Search Ads, organic, paid UA, and cross-promotion
- Identify which acquisition sources produce users who drop early in onboarding versus users who convert
- Real ROAS calculation uses actual revenue from RevenueCat, not platform-reported conversions
- Campaign optimization becomes data-driven instead of based on platform claims
What the complete funnel tells you: You can finally answer: which campaign brings users who reach the paywall, convert to paid, and renew? And which campaign brings users who drop on onboarding screen one? That is the difference between spending on volume and spending on revenue.
Start Finding Your Onboarding Leaks
If you are using RevenueCat to manage subscriptions, you already have the revenue data. What you are missing is the screen-level journey that connects install source to revenue outcome. Grometrics fills that gap with first-party tracking that ties onboarding flow to RevenueCat transactions.
Connect your payments to Grometrics, install the SDK, and within minutes you will see where users drop before reaching your paywall. You will see which acquisition sources produce paying customers and which produce users who bounce early. You will have the data to fix the right problem instead of optimizing the wrong funnel stage.
The revenue leak in your mobile app is not at the paywall. It is in the screens before the paywall. Find it with RevenueCat funnel analysis from Grometrics.
