Stop fake installs on mobile app install campaigns
Fake installs are the core of invalid mobile traffic: simulated install events generated without any real user downloading or using your app. Tapper detects fake installs across every generation method and removes them before they corrupt your CPI and MMP data.

Fake installs are the most direct drain on your mobile UA budget
Fake installs are the purest form of invalid mobile traffic: install events claimed and billed at your CPI rate that were never made by a real user. They are generated through multiple methods, including SDK spoofing (simulating install signals in software without any device), device farms (using real devices with scripted install automation), and click injection (firing an install-claiming click at the exact moment an organic user installs, stealing credit for a genuine download). Each method produces a billable install event in your MMP, and each consumes your UA budget without delivering a user who can generate revenue.
The impact on your campaign optimization is systematic. Your MMP reports installs at your target CPI, but the users those installs represent never engage, never retain, and never purchase. Your day-one retention collapses. Your revenue-per-install falls far below projections. Automated bidding systems interpret this as a quality problem with your creative or audience and adjust bids downward, reducing your reach among genuine users. The fake installs suppress your real campaign performance from within your own data. Tapper analyzes install events across all generation methods, using CTIT patterns, session behavior, device cluster analysis, and SDK signal verification to distinguish real installs from fabricated ones.
How Tapper stops fake installs on Mobile app install
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, monitoring every install event and the click chain leading to it for invalid traffic signals across all generation methods.
02
Fake install signals detected at every layer
Tapper applies CTIT analysis, SDK signal verification, device cluster detection, and session behavior analysis to identify install events that do not represent real user downloads, regardless of the method used to generate them.
03
Clean CPI and protected UA budget
Fake installs are flagged and removed from your MMP attribution before they affect your cost-per-install calculations or your cohort analysis. Your budget reaches real users only.

“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
Click injection is an Android-specific attribution abuse technique where a malicious app installed on a real user device listens for app install broadcast signals from the operating system. When it detects that the user is installing your app, it immediately fires an invalid click claiming the attribution credit. The install is genuine, but the attribution is stolen, meaning you pay a CPI to a bad-actor network for an install that was actually driven by organic discovery or another paid channel.
SDK spoofing generates install signals in software without any real device. While the device-level signals can be made to appear legitimate, the full behavioral profile of a spoofed install differs from a genuine one: there is no natural session initiation, no genuine interaction pattern within the app, and no coherent user journey following the install event. Tapper analyzes the complete post-install session to identify spoofed installs that pass surface-level signal checks.
Removing fake installs improves your network quality scores over time. Networks that use engagement signals to evaluate traffic quality will see your retained and engaged users improve as a proportion of reported installs. Bidding algorithms receive accurate quality signals and can optimize toward sources that genuinely drive valuable users rather than high-volume invalid install sources.
