The Hidden ROI of App Localization: 128% More Downloads?

Nov 28, 20244 min readBy Glovio Team

The English Saturation Problem

The English-speaking app market is the most competitive in the world. Yet, 88% of the world's top app download markets are non-English speaking. If you're only publishing in English, you're ignoring the vast majority of your potential users.

The Data: Why Localization Wins

Recent 2024 studies have quantified the impact of localization, and the numbers are staggering:

  • 128% Download Boost: On average, apps that localize for new markets see a 128% increase in downloads within weeks.
  • 767% Visibility Spike: For iOS apps, simply localizing the Title and Description keywords can lead to a 767% increase in impressions in that region.
  • 26% Revenue Uplift: Users are far more likely to pay for in-app purchases when the currency and UI are in their native language.

Trust = Revenue

It comes down to trust. 72% of consumers say they are more likely to buy a product with information in their own language. By localizing, you aren't just translating words; you're signaling respect and commitment to that user base. This builds the trust necessary for monetization.

"Localization is the single most effective lever for lowering your Customer Acquisition Cost (CAC) while increasing Lifetime Value (LTV)."

Start Small, Win Big

You don't need to translate into 50 languages overnight. Start with high-growth markets like Brazil (Portuguese), Japan, or Germany. Even a single new language can double your addressable market.
