Discounty: Bulk Discount Sales in 38 months, Essential Countdown Timer Bar in 47 months, Brevo PushOwl: Email,Push,SMS in 58 months, and Hextom: Upsell Sales Boost took 78 months to cross the same milestone, a 51-month spread between the fastest and slowest in the set.

The 51-month gap between Essential Announcement Bar's and Hextom: Upsell Sales Boost's time-to-1,000 highlights how unevenly product-market fit landed across this flash sales set — the leader found its merchant audience early, while late-rampers took multiple years to reach the same review depth. For merchants comparing these apps today, slower-ramping apps may have closed the functionality gap but still operate on smaller review bases.
