App Marketing That Pays for Itself: Paying Users, Not Just Installs
Installs are easy to buy. Users who register, transact and subscribe are not. We run Google App Campaigns and Meta app ads for fintech, subscription, health & fitness and education apps — measured on what users do after the install.
In short: ConvertLab360 manages user acquisition for mobile apps on Google App Campaigns and Meta. We set up MMP and in-app event tracking first, filter install fraud, check ad-policy requirements for financial apps, and move bidding from installs to registrations, first transactions and subscriptions as soon as the data allows. It starts with a free App Growth Audit.

Where App Demand Is Growing
The app market has shifted. Users now spend more inside non-game apps than in games — which changes who is buying ads and what they optimize for.

| Signal | Figure | What it means for advertisers |
|---|---|---|
| Non-game in-app purchase revenue, 2025 | +21% year over year — larger than games for the first time | More apps can afford paid acquisition and optimize toward revenue |
| Generative AI apps, 2025 | Downloads +148%, revenue +254% | Crowded, fast-moving category; creative testing decides winners |
| Game in-app revenue, 2025 | +1.3% | Games hold budgets steady; non-game apps compete harder for the same users |
| Android install-fraud rate, finance apps | About 31% (games about 7%) | Fintech campaigns need fraud filters before scaling |
App Categories We Work With
Categories where users pay or transact inside the app, so campaigns can be judged on revenue, not install volume.
Fintech & Banking
Neobanks, payments, wallets and investing apps. Optimized toward verified registration (KYC) and first transaction, with fraud control and financial-services policy checks per market.
Lending
Personal and consumer loan apps where policy allows. Ads, landing pages and store listings built to the disclosure rules of each country before any spend.
Subscription Utilities & AI Tools
Photo and video editors, scanners, productivity and AI apps. Trial-to-paid tracking and fast creative rotation for one of the fastest-growing categories.
Health & Fitness
Workout, nutrition, sleep and meditation subscriptions. Seasonal peaks planned in advance; no medical claims and no targeting by health condition.
Education & Languages
Language, test-prep and skills apps with longer paths to payment, so in-app events and cohorts matter more than install cost.
Local Service Apps
Booking, delivery and clinic apps that combine app campaigns with Search and local intent.
Why App Campaigns Stop Paying Off
Most app accounts we look at are buying installs. The problem is what happens after them.
Optimized for Installs Only
Install bidding finds the cheapest users — often the least likely to register, transact or subscribe.
In-App Events Not Sent to the Networks
If Google and Meta never see registrations or payments, they cannot learn which users are worth more.
Fraudulent Installs
Click spam and fake installs inflate results, especially in finance. Without filters, reports look better than reality.
iOS Measured Blind
Badly mapped SKAdNetwork / AdAttributionKit conversion values hide the events that matter on iOS.
Policy Disapprovals for Financial Apps
Missing disclosures, licenses or certifications get ads and sometimes accounts suspended.
Creative Fatigue
App campaigns burn through creatives fast. Without a steady testing plan, costs climb week after week.

App Growth Audit
We review your Google App Campaigns, Meta app ads, MMP setup, store listings and the last 60–90 days of installs against registrations, transactions and subscriptions.
-
Tracking and Fraud Control
MMP or Firebase events mapped to registration, KYC, first transaction or trial and purchase; fraud filters on; iOS conversion values set up.
-
Policy and Store Readiness
Financial-services rules for each market, required disclosures, and store listings that convert the traffic you pay for.
-
Campaigns by Goal and Market
Separate campaigns for installs, in-app actions and value, by country and platform, with budgets moving toward the events that make money.
-
Creative Testing and Scaling
A steady pipeline of video, image and playable-style concepts, weekly cohort reporting, and budget scaled on cost per paying user.
App Marketing Metrics That Actually Matter
Cost per install is where most reports stop. These are the numbers we report on.
| Metric | How it's calculated | What it tells you |
|---|---|---|
| Cost per install (CPI) | Ad spend ÷ installs | How cheap traffic is. Says nothing about user value. |
| Install-to-registration rate | Registrations ÷ installs | Whether you are buying real, interested users. |
| Cost per paying user | Ad spend ÷ users who transact or subscribe | What a customer actually costs you to win. |
| Day-7 / day-30 retention | Active users on day N ÷ installs | Whether users stay long enough to pay back. |
| Cohort ROAS | Revenue from an install cohort ÷ its ad spend | The number that decides where the next dollar goes. |
| Rejected / fraud install rate | Fraud-flagged installs ÷ all installs | How much of the budget never reached a real user. |
What's in the Free App Growth Audit

Install-to-Value Funnel
How many paid installs register, transact or subscribe — by network, country and platform.

Which in-app events reach Google and Meta, and whether bidding can use them.
Fraud Signals
Suspicious install patterns, click spam and sources worth excluding.
iOS Measurement
How conversion values are mapped and what is invisible on iOS today.
Policy and Store Listing
Policy risks for your category and market, and how the store page converts.
Creative Review
Which concepts drive paying users, and how fast creatives are fatiguing.

App Marketing: Common Questions
Mostly fintech (banking, payments, lending, investing), subscription utilities and AI tools, health & fitness, and education apps. These are categories where users pay or transact inside the app, so campaigns can be optimized toward revenue rather than installs. We don't run gambling or betting apps.
Yes, but under NDA. App clients — especially in fintech — usually don't allow their numbers to be published, and we don't publish anonymized figures that could identify them. On a call we can walk through the approach and anonymized results in more detail. The free App Growth Audit shows what we find in your own account.
Start where the data allows. Google App Campaigns can optimize for installs, in-app actions or value. Install campaigns are cheap but bring many users who never register. Once your app sends enough in-app events to Google, moving bidding to registrations, first transactions or subscriptions usually brings better users for the same budget.
Because finance is one of the most targeted categories for install fraud. AppsFlyer's 2026 fraud report puts the Android fraud rate for finance apps around 31%, against about 7% for games. Without fraud filters in your MMP and a check of install-to-registration patterns, part of the budget pays for installs that were never real users.
Financial products are a restricted category. In the United States, for example, Google does not allow ads for personal loans with an APR of 36% or more, requires repayment terms of at least 61 days, and requires the maximum APR and a representative cost example to be disclosed. Many countries add licensing or certification requirements. We check the current policy for each market before launch.
For anything beyond a small test, yes. A mobile measurement partner attributes installs and in-app events across Google, Meta and other networks, filters fraud and handles iOS privacy frameworks. If you already use Firebase only, we can start with that and plan the MMP setup together.
Apple's privacy rules limit user-level tracking, so iOS results come through SKAdNetwork / AdAttributionKit with delays and less detail. Conversion values have to be mapped carefully so the most important in-app events are still visible to the ad networks.
No. Costs depend on your market, category, creatives, store listing and the in-app experience. What we commit to is clean tracking, fraud control, a testing plan and weekly reporting on installs, registrations, paying users and their cost.
