We measure what users do in your app, and which ad brought them, with the same logic as your web data.

Roicool's Firebase and mobile measurement service covers the app event plan, Firebase and GA4 setup, the Google Ads link, choosing a mobile measurement partner where needed, a measurement design that accounts for the iOS permission prompt (ATT), and joining web and app data in the same GA4 property.

Four problems we solve.
Scope
Core events and parameters such as screen views, sign-ups, purchases and subscriptions, named the same way as your web events.
Your developers add the SDK and event code; we test together in DebugView.
The Firebase link for Google Ads; assessing a mobile measurement partner for other networks; the effect of the permission prompt and SKAdNetwork on iOS.
Combining web and app streams in the same GA4 property; BigQuery export if needed.

In mobile measurement the event starts in the app; the Firebase SDK logs it, Firebase / GA4 counts it as a key event in the app stream, exports the raw data to BigQuery, passes it to Google Ads and Meta as a conversion, and the result lands in the Looker Studio report. Tools we use for this: Looker Studio, Google Ads, Meta CAPI, Clarity, Semrush, Zoho CRM, Photoshop.

Cases
At Royal Hair, Google Ads captures demand that already exists while a multi-stage Meta funnel carries cold audiences toward a booking. A $60,000 monthly budget is balanced between those two jobs, and CAPI keeps conversion data clean at every stage. The published results: 14x average ROI, an 8% conversion rate and an $11 lead cost, which can vary seasonally.

Partnerships and certifications
Google Analytics in Firebase sends app data to your GA4 property, so mobile app data follows GA4's data model and can be seen alongside web data in the same property.
Google Ads uses the Firebase link, other networks need a mobile measurement partner (MMP), and on iOS SKAdNetwork data is used. Which ones you need depends on your ad channels.
We write the event plan, parameters and test scenarios; your developers add the SDK and event code to the app. We test and validate together in DebugView.
When a user does not give permission, the device ID cannot be used for ad measurement, so some ad-driven installs and conversions are modeled or reported in aggregate. We build the measurement plan with this in mind.
Web and app streams can sit in the same GA4 property; for signed-in users, user_id makes cross-platform analysis possible.
