Australia is the largest single market for theme extension apps at 26.1% — but no country dominates, meaning theme extension apps serve a globally distributed merchant base. Canada follows at 15.4%, with France at 14.5%. Together, the top 3 markets account for 56.0% of theme extension app installs worldwide. Hungary (14.3%) and United States (8.7%) round out the top 5.

With Australia's 26.1% as the largest single market and the rest spread across many countries, the leading theme extension apps tend to be region-agnostic by design — geography matters less for app choice here than features, pricing, and support quality.
