Essent Cart Drawer Cart Upsell in 18 months, Upsell & Cross Sell — Selleasy in 32 months, and Kaching Bundles App & Upsells took 37 months to cross the same milestone, a 21-month spread between the fastest and slowest in the set.

1 app on this chart hasn't yet crossed 1,000 reviews: Bundlex Product Bundles Upsell at 145 cumulative reviews. Bundlex Product Bundles Upsell is closest to the milestone — its current count puts it roughly 14% of the way to 1,000.

The 21-month spread between Essential Upsell & Cross Sell and Kaching Bundles App & Upsells reaching 1,000 reviews suggests a competitive upselling 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.
