Fake install fraud on mobile app install campaigns
Fake installs are the core of mobile app fraud: 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 mobile app fraud: 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 optimisation 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 fraud suppresses your real campaign performance from within your own data. Tapper analyses install events across all generation methods, using CTIT patterns, session behaviour, 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 fraud 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 behaviour 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.

“Tapper played a key role in improving the efficiency of Du's performance marketing activity by addressing traffic quality issues within campaigns. Following implementation, Du achieved a 13% reduction in CPA and an 8.6% increase in order rate, demonstrating a clear improvement in conversion quality and overall campaign effectiveness.”
Joseph Elbcherrawy
Client Leadership Director, Mindshare, a WPP Media Brand
“During our Tapper trial for INFINITI, 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.”
David Barnes
Data & Technology Lead, Omnicom Group
“With Tapper's protection we were able to identify and block invalid clicks in real time. The impact was immediate as our cost per acquisition dropped by 30% and ROAS improved significantly. More importantly, Tapper gives us the confidence that our campaigns are reaching genuine customers, which makes it truly invaluable.”
Dimitris Bakas
Senior Performance Marketing, Public Group
“We started using Tapper to get better visibility on where our clicks were coming from, and ended up cutting wasted spend by over 12%. The performance uplift was clear, and for the first time, we could trust the numbers we were seeing. It's a total game-changer for campaign integrity.”
Stuart Parkin
Director of Operations, Regit
“Tapper's blocking technology purifies our paid media traffic which roughly equates to a 36x return against its subscription costs. It's certainly one of the easiest-to-implement tools in our entire marketing stack.”
Reno Mindemann
Head of Growth, Kama Capital
“We've been using Tapper for over a year now, and it has become a core part of how we run paid media. Invalid traffic was always something we knew existed but couldn't really act on. Tapper changed that. We're now saving up to $50K per year, and on PureSquare specifically, we saw around a 20% decrease in CPA. Based on these results, we decided to roll it out across other ventures under Disrupt as well.”

Frequently asked questions
Everything about fake installs on Mobile App app install.
Click injection is an Android-specific fraud 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 a fraudulent click claiming the attribution credit. The install is genuine, but the attribution is stolen, meaning you pay a CPI to a fraudulent 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 behavioural 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 analyses 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 optimise toward sources that genuinely drive valuable users rather than high-volume fraudulent install sources.
