United States dominates demand for custom links apps with 41.3% of all tracked installs — a single market that effectively defines the category's product priorities. United Kingdom follows at 10.3%, with Canada at 6.0%. Together, the top 3 markets account for 57.7% of custom links app installs worldwide. Australia (5.4%) and Germany (5.0%) round out the top 5. United Kingdom is the fastest-growing market this month (+1.4pp), pointing to accelerating demand outside the established leaders.

With 41.3% of custom links app installs concentrated in United States, the leading apps in this category typically prioritize United States-based merchants for localization, currency, and support hours — merchants in United Kingdom (10.3%) and other regions sometimes find better fit in apps that over-index outside United States.

Appointment Booking Cowlendar reached 1,000 reviews in 34 months since launch — the fastest ramp among the top 5 custom links apps tracked here. BixGrow Affiliate Marketing in 46 months, Appointment Booking App Apntly in 47 months, and UpPromote Affiliate Marketing took 52 months to cross the same milestone, a 18-month spread between the fastest and slowest in the set.

1 app on this chart hasn't yet crossed 1,000 reviews: Tevello Courses & Communities at 732 cumulative reviews. Tevello Courses & Communities is closest to the milestone — its current count puts it roughly 73% of the way to 1,000.

The 18-month spread between Appointment Booking Cowlendar and UpPromote Affiliate Marketing reaching 1,000 reviews suggests a competitive custom links category — leaders pulled ahead by roughly a year, but no single app dominated launch-to-milestone speed. The ramp differences likely reflect both product quality and timing-of-launch rather than one clear category winner.
