Number of European online banking app downloads worldwide 2015-2023, by bank

As of December 2023, the six app-only digital banks included in this statistic had more than 117 million app downloads combined. The most popular of these banks in terms of downloads was the London-headquartered Revolut, which has opted for global expansion over a single market approach. As of January 2024, the banking app was particularly popular in the United Kingdom (UK), France, Romania and Poland.

Number of active customers

Due to multiple downloads and inactive customers, looking at the number of active customers as announced by banks could be deemed a more accurate depiction of customer growth. In February 2018, Revolut announced that they had hit 1.5 million customers, a figure that had grown to 18 million by 2022 and to 35 million by October 2023. The incredible acceleration of new customers joining these online-only banks has been mirrored by the Berlin-based N26 and fellow London-headquartered Monzo.
