On December 23, 2025, Zacks published an analysis comparing Duolingo (DUOL) with mobile technology company AppLovin (APP). The report concluded that Duolingo currently represents the more compelling investment opportunity.

The analysis highlighted Duolingo’s strong growth trajectory. Consensus estimates project significant year-over-year growth for 2025. Sales are expected to rise 38%, while EPS forecasts indicate a 344% increase.

Zacks noted Duolingo’s more attractive valuation. Its forward sales multiple currently trades below its 12-month median, suggesting the market may underappreciate its long-term potential. In contrast, AppLovin also shows strong growth, but its valuation is considered higher.

The report frames Duolingo as a favorable growth stock, citing its scalable, AI-driven model. This foundation, supported by expanding learning verticals and cost-efficient scalability, drives its future performance in the education technology sector.
