Pure player BNPL apps Affirm and Afterpay had about as many active users as PayPal, with PayPal also having Pay in 4 embedded into its app in the United States. This is according to a ranking of the biggest apps that can offer BNPL services, based on a minimum of 10,000 monthly active users (MAU) or more. The United States has several buy now, pay later services - with the likes of Zip (its U.S. branch, formerly QuadPay), Bread, Beem, and Perpay attracting all their users from within the country. Roughly 18 percent of the global MAU of the Klarna app came from the United States.

App on Apple App Store or Google Play Store offering BNPL services
This statistic is the result of research into roughly 200 different apps that offer BNPL across the world. For more information, see the "Details" tab; * Exact user figures are unavailable, as BNPL is embedded in a larger app.
Supplementary notes
All figures concern apps that can be downloaded on either the Apple App Store or Google's Play Store. This leads to several data limitations:
Embedded payment services within larger (super) apps are not tracked separately. One important example is, among others, PayPal's Pay in 4. Additionally, not all BNPL options are available everywhere in the world;
Occasionally, download options of BNPL are not offered on the Apple App Store or Play Store. This is significant to note for countries which may not use these online marketplaces, or have an outright ban on them.
Some of the apps under review are not necessarily a "pure" BNPL player: The PayPal app, for example, has Pay in 4 embedded in it for certain countries - whereas Klarna is devoted solely to BNPL. It is therefore unclear whether these figures are fully comparable.
The names provided are based off multiple publications covering BNPL brands, and focus on BNPL providers with an app. If an app does not feature in the statistic, it is because download figures were too small. Note, however, that the selection of players is not exhaustive and does not include, for example, white labels as these do not have their own app - such as Addi, PayU, or Swap. Some of the apps researched include:
