Where European Finance Apps Win or Lose Users

TL;DR

• European finance app installs hit 960 million in 2025, but growth has flatlined at 0.4%. The volume era is over.
• BNPL and insurance apps are growing fast; crypto fell 35%. The market is maturing around everyday utility, not experimentation.
• Neobanks are winning acquisition, traditional banks are winning retention. Day 30 retention for incumbents runs 1.5 to 2x higher.
• Web-to-app drives 41.8% of owned media conversions in Western European finance apps, but most brands still can’t measure the handoff end-to-end.
• Nearly one in two investment app installs in Western Europe was flagged as fraudulent, distorting CPI benchmarks, cohort data, and ROAS across the category.
• Session growth is outpacing install growth across every sub-category. The brands pulling ahead are measuring engagement, not just acquisition.

In 2025, finance apps were downloaded 960 million times in Europe, but the market only grew by 0.4%. It appears that the volume story that drove European finance app growth for the better part of a decade has run its course. In such a reality, what happens after the install matters more than the install itself.

For years, the growth of the European finance app space has been driven by volume. Brands expanded into new markets, scaled onto new platforms, and measured success by how many installs they could stack up. But the market is now mature, acquisition costs are climbing, and the brands pulling ahead aren’t necessarily spending more to get users in. They’re doing a better job of keeping them, and connecting the fragmented user journey. 

It’s one of several important takeaways from The State of Finance for Marketers in Europe report, which was produced in collaboration with Sensor Tower and Google Ads. It is based on AppsFlyer data across approximately 300 European finance apps and covers 2.4 billion installs and $1 billion in user acquisition and remarketing spend between Q2 2024 and Q1 2026.

Why European finance app install growth has flatlined

960 million installs and 0.4% growth sounds like a market standing still. It isn’t. The total is stable, but the mix has shifted sharply. Understanding what grew and what didn’t tells you more about where the finance app market in Europe is heading than the headline figure does.

Buy Now, Pay Later apps grew 40% year on year. Insurance and budgeting apps also gained momentum, while Cryptocurrency downloads fell 35%. Consumers are moving away from financial experimentation to apps that solve specific, everyday problems: managing debt, controlling spending, building savings. The finance category isn’t shrinking. It’s maturing around utility, and the sub-categories growing fastest are the ones that fit into daily financial life rather than sitting alongside it.

The platform picture is shifting in parallel. Android accounts for 16.2% of finance app installs from paid channels, nearly double the 9.2% on iOS. Android’s lower CPIs make it the default scale lever for most finance marketers. But iOS users consistently deliver stronger Day 1 and Day 30 retention. The data suggests the lower paid share on iOS may reflect underinvestment rather than a genuine ceiling on performance.

Eastern Europe is a different market entirely. Android banking installs nearly tripled between Q2 2024 and Q1 2026. Sessions are rising fast alongside installs, with banking apps moving from occasional utility to daily financial habit. Finance marketers running a single European strategy built on Western European data are optimizing for the wrong conditions in half their markets.

How the neobank vs. traditional bank split actually plays out

Banking apps accounted for 338 million European downloads in 2025, according to Sensor Tower, which is more than wallets, crypto, insurance, and investment apps combined. But within that split, the competitive landscape is fracturing along a clear fault line: neobanks are winning acquisition, traditional banks are winning retention, and the gap between the two is widening.

In France, neobanks attract twice as many new users as incumbents. Revolut is the only brand achieving meaningful scale across multiple markets simultaneously, holding the top position in Spain, France, and Italy while performing strongly in the UK.

Traditional banks, meanwhile, are holding their ground on engagement. AppsFlyer data shows Day 30 retention rates for traditional banks reaching 1.5 to 2 times higher than neobanks. Acquiring users at scale without retaining them is an expensive way to stand still. The metric that matters more than how many users you bring in is how many are still active a month later.

Jonathan Briskman, Director of Market Insights at Sensor Tower, points to a structural opportunity traditional banks are underusing. “Traditional banks already offer many of these products,” he says, “but can benefit from more targeted marketing around their key differentiators while reducing friction to make it easier for younger, mobile-first users to sign up.” In other words, the product gap between neobanks and incumbents is smaller than the marketing gap.

One pattern holds across every European market: standalone digital brands consistently outperform their parent institutions’ legacy apps. Crédit Agricole in France competes with neobanks through Ma Banque, a purpose-built digital brand, rather than by modernizing its existing app. Modernizing a legacy app and building a mobile-first experience are not the same thing, and users can tell the difference.

Where users drop off, and why the web-to-app handoff is key

Many, if not most European finance consumers start their journey on the web and convert in the app, and the distance between those two moments is where most European finance brands are losing users, and where most still lack the visibility to do anything about it.

In Western Europe, web-to-app drives 41.8% of all owned media conversions in finance apps. It is the dominant channel by a significant margin. Consumers research financial products online, comparing rates, reading reviews, checking eligibility, before converting in-app. The brands that can measure and optimize that handoff have a structural advantage. The ones that can’t are making budget decisions with an incomplete picture.

The handoff itself is where conversions are made or lost. A user who clicks through from mobile, lands in an app store, downloads the app, and then has to restart the journey from scratch has experienced a broken funnel. The context is gone. The intent signal is lost. Deep linking, routing users directly to the right in-app destination rather than a generic home screen, is how leading finance brands are closing that gap and driving conversions.

The assumption worth challenging is that web and app are two separate channels that can be measured and budgeted independently. Users don’t experience them that way. A customer who researches a product on mobile web and converts in the app has completed one journey, not two. Measuring them separately produces a fragmented picture that systematically undervalues the channels driving early-stage intent.

What fraud is doing to your finance app economics

Nearly one in every two investment app installs in Western Europe was flagged as fraudulent during the period covered by this report. That is not an edge case. It is a structural feature of the highest-value segment of the finance app market, and it is distorting the economics of every campaign running in it.

The logic is straightforward. Higher CPI rates attract more fraudsters. Investment apps carry the highest transaction values and the highest payouts per install, which makes them the most attractive target. Digital wallets and banking apps suffer proportionally lower fraud rates, not because they are better protected, but because the financial incentive is lower.

The iOS finding challenges a widely held assumption. iOS fraud rates run higher than Android across most of the finance vertical. That is a surprising result given iOS’s tighter guardrails and well-documented quality premium in paying users, retention, and engagement. But iOS’s higher CPIs have made it a more attractive target for fraudsters. The quality advantage is real. It only holds when fraud is filtered out first. Without robust fraud detection upstream, the iOS cohort is diluted, acquisition costs are inflated, and the retention data that follows is built on a contaminated base.

Not all media sources carry the same risk. Self-Reporting Networks and Demand-Side Platforms (DSPs) consistently deliver more reliable traffic in the finance vertical. Affiliate networks carry the highest fraud exposure. That makes the media mix a fraud prevention decision as much as a performance one, and it means that optimizing purely on CPI without accounting for fraud rate can produce the wrong answer.

The measurement consequence is the part most finance marketers underestimate. Inflated CPI benchmarks, distorted cohort analysis, and false confidence in ROAS figures are all downstream effects of unfiltered fraud. Fraud detection is not an optional add-on. It is what makes the rest of your measurement accurate.

What the winning finance brands are doing differently

Session growth is outpacing install growth across every finance sub-category in Europe. Banking app users in Europe spent around 12.5 hours per download in the first four months of 2026. Investment and financial management apps recorded 8.8 hours per download. The market has moved from acquisition-driven growth to engagement-driven value. The brands winning are the ones whose measurement has moved with it.

Three things consistently separate the brands pulling ahead:

1. They treat the web-to-app journey as a single connected measurement. Web budget and an app budget is not managed in separate teams with separate reporting, but in one funnel with one view of what is working at each stage. The cross-platform handoff is where conversions are decided. Measuring it end-to-end is the minimum requirement for making good investment decisions.

2. They have fraud filtering built into the foundation, not bolted on afterward. The finance brands that trust their iOS data, their cohort analysis, and their ROAS figures are the ones that have cleaned the signal before it reaches the decision layer. The ones making decisions on unfiltered data are optimizing toward a number that doesn’t reflect reality.

3. They are building for engagement as a growth metric, not just a retention metric. As Jonathan Briskman, Director of Market Insights at Sensor Tower, puts it, AI will increasingly position finance apps as proactive financial assistants, helping users budget, pay, and invest rather than waiting to be opened. The brands building that experience now are the ones that will be essential to users’ daily financial lives in the years ahead.

The fragmentation running through European finance app marketing (neobanks vs. traditional banks, Western vs. Eastern Europe, web vs. app, clean signal vs. contaminated data) points to a single problem: measurement infrastructure that was built for a simpler market, now trying to do the job in a more complex one.

What the data tells us about where European finance is heading

The headline install figure hasn’t moved much, but everything underneath it has.

European finance app growth has largely shifted from the install to the session, from acquisition to re-engagement, from single-channel to cross-platform. The brands pulling ahead are the ones who can see the full journey clearly enough to know where it breaks and act on it before users drop off.

The fragmentation tax is real and measurable. Flat installs, distorted fraud economics, and disconnected web-to-app journeys are all symptoms of the same underlying issue: measurement that hasn’t kept pace with the market it’s supposed to describe. The gap between brands that measure the full journey and those that don’t is wide enough to matter. For finance marketers building out their measurement infrastructure now, that gap is the opportunity.
