Where European Finance Apps Win or Lose Users

Summary

The European finance app market has matured: 960 million installs in 2025 grew only 0.4% year-on-year, marking the end of volume-driven growth. Sub-category shifts reveal consumer preference for utility: Buy Now, Pay Later apps grew 40%, insurance and budgeting apps gained momentum, while cryptocurrency downloads fell 35%. Neobanks are winning acquisition—in France, they attract twice as many new users as incumbents, and Revolut holds top positions in multiple markets. However, traditional banks excel at retention: day 30 retention rates for incumbents are 1.5 to 2x higher than neobanks, highlighting that acquisition without retention is unsustainable.

Web-to-app is the dominant conversion channel, driving 41.8% of owned media conversions in Western European finance apps. Yet most brands lack end-to-end measurement of this journey, losing users in the handoff. Deep linking is critical to maintaining intent. Fraud is a structural problem: nearly 1 in 2 investment app installs in Western Europe is fraudulent, distorting CPI benchmarks, cohort data, and ROAS. iOS fraud rates exceed Android due to higher CPIs, making robust fraud detection essential for accurate measurement.

Session growth now outpaces install growth across all sub-categories, indicating a shift from acquisition to engagement. Winning brands integrate web and app measurement, embed fraud detection early, and optimize for engagement as a growth metric. The fragmentation between neobanks vs. incumbents, Western vs. Eastern Europe (where Android banking installs tripled), and clean vs. contaminated data underscores the need for measurement infrastructure that matches market complexity.

Analyst Note

As someone who's been optimizing UA for finance apps across Europe, this report hits home. The headline—960M installs but only 0.4% growth—confirms what we've felt: the low-hanging fruit is gone. BNPL exploding 40% and crypto tanking 35% isn't surprising; consumers want tools for daily life, not speculation. But the fraud stat is staggering: nearly 1 in 2 investment app installs flagged as fraudulent in Western Europe. That means if you're running CPI campaigns in that vertical, your ROAS is built on sand. I've seen iOS CPIs look great on paper but fail to convert—now I know why. iOS fraud rates being higher than Android flies in the face of conventional wisdom but makes sense given higher payouts. The takeaway: don't trust any iOS data without rigorous fraud filtering upstream.

Web-to-app driving 41.8% of conversions—but most teams still silo web and app budgets. I've been pushing for unified measurement for years; this report gives me ammunition. The gap between neobank acquisition and incumbent retention is a classic 'spend more to get users, then lose them' trap. The real opportunity lies in fixing the handoff and using deep linking to preserve context. Session growth outpacing installs? Finally, metrics teams are moving beyond vanity installs to engagement. But if your fraud detection isn't built in, those engagement numbers are also suspect. This report should be mandatory reading for every UA manager dealing with finance apps—ignore it at your peril.
