United States is the largest single market for square apps at 19.7% — but no country dominates, meaning square apps serve a globally distributed merchant base. Australia follows at 12.2%, with United Kingdom at 6.1%. Together, the top 3 markets account for 38.0% of square app installs worldwide. Netherlands (5.9%) and Canada (5.7%) round out the top 5. Netherlands is the fastest-growing market this month (+2.8pp), pointing to accelerating demand outside the established leaders.

With United States's 19.7% as the largest single market and the rest spread across many countries, the leading square apps tend to be region-agnostic by design — geography matters less for app choice here than features, pricing, and support quality.
