VizualStocks APIOperating KPI and segment definitions available for Duolingo (DUOL) through the VizualStocks API.
Revenue from third-party advertisements shown primarily to free users after lessons in Duolingo's learning app. It is one way Duolingo monetizes its large unpaid audience without putting core learning content behind a subscription.
advertisingRevenueAverage number of unique accounts per day that engaged with the Duolingo app or the learning section of its website during the reporting period. It measures learning engagement, not simply app opens or registered accounts.
dailyActiveUsersRevenue from Duolingo's online, remotely proctored English proficiency test used for admissions and other language-certification needs. Revenue is recognized when a purchased test is proctored, not when the customer initially pays.
duolingoEnglishTestRevenueAverage number of unique accounts per month that engaged with the Duolingo app or the learning section of its website during the reporting period. It includes free and paid learners and is broader than the paid-subscriber count.
monthlyActiveUsersDuolingo revenue outside subscriptions, mainly advertising, the Duolingo English Test and in-app purchases of virtual goods. It captures monetization of free learners and standalone products.
otherProductRevenueRevenue Duolingo reports for geographic markets not separately disclosed in its geographic revenue breakdown during the period, measured in U.S. dollars.
otherRevenueByGeographyUnique user accounts with an active paid Duolingo subscription at period end. Free trials and non-paying members of a family plan are excluded, and one account counts once even if it buys multiple subscriptions.
paidSubscribersRevenue Duolingo reports for markets outside the separately disclosed regions in its geographic revenue breakdown during the period, measured in U.S. dollars.
