Fake installs corrupting in-app event campaign data
Fake installs that enter your MMP feed ghost users into your in-app event funnel, collapsing event completion rates and corrupting the CPA data your campaigns optimize on. Tapper removes fake installs before they pollute your in-app event attribution.

Fake installs feed ghost users into your in-app event funnel and destroy your CPA data
In-app event campaigns are uniquely exposed to fake installs because every fake install that enters your MMP creates a phantom user in your post-install funnel who will never complete any genuine event. These ghost users become denominator noise in your event completion rate calculations: your tutorial completion rate falls, your purchase conversion rate drops, and your CPA for every downstream event rises, even if your genuine user acquisition is performing well. The damage at the install level propagates through every metric in your in-app event reporting.
The insidious nature of this problem is that it's often misdiagnosed. When your in-app event rates fall, the natural interpretation is a product quality issue, an onboarding friction problem, or a targeting mismatch. Teams respond by changing their creative, adjusting their audience targeting, or revising their onboarding flow, when the actual problem is that their install base is populated with users who never existed. Tapper identifies and removes fake installs before they enter your MMP, ensuring that your in-app event funnel is built on genuine users whose behavior accurately reflects your product's performance.
How Tapper stops fake installs on Mobile in-app events
Three steps from connection to clean campaign data, no engineering required.
01
Connect your MMP and ad networks
Tapper integrates with AppsFlyer, Adjust, Kochava, Singular, and Branch, analyzing install events and the click chain leading to them before they populate your in-app event funnel.
02
Fake installs detected and removed at the install layer
Tapper applies CTIT analysis, SDK signal verification, device cluster detection, and session behavior review to identify fake installs before they create ghost users in your post-install event funnel.
03
Clean event funnel and accurate CPA data
With fake installs removed, your in-app event funnel reflects genuine user behavior. Your event completion rates, CPA calculations, and LTV projections are built on real users only.

“We uncovered low-quality traffic that wasn't visible inside the platforms. Removing it delivered a 14% uplift in conversions and an 11.4% reduction in CPA, a meaningful efficiency gain for INFINITI's 2026 growth plans.”

“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimizes against cleaner signals and the efficiency comes through quickly. For AMA Nissan, that was a 40% lift in conversion rate and a lower CPA on Google, with nothing else in the setup changing. That is the kind of result we want to offer clients as a matter of course.”

Frequently asked questions
Network algorithms optimizing in-app event campaigns use post-install event data to find more users likely to complete target actions. When fake installs populate your MMP with ghost users who never engage, the event completion rate signals sent back to the network algorithm are artificially depressed. The algorithm interprets this as targeting the wrong audience and adjusts, reducing delivery to the very users most likely to genuinely engage with your app.
Both are important, but fake install detection has upstream priority because fake installs corrupt every downstream metric. A ghost user from a fake install cannot complete any genuine event, so their presence in your install cohort degrades all event funnel metrics. Removing fake installs at the install layer protects your entire in-app analytics stack. Tapper applies both install-level and event-level analysis simultaneously.
Yes. Tapper provides per-source fake install rate analysis alongside per-source event completion rate data, so you can identify which networks are delivering installs that never convert to any in-app event. Sources with high install volume but near-zero event completion are the strongest indicators of fake installs affecting your funnel.
