As an indie developer, you wear many hats: designer, developer, marketer, and support. Adding 'translator' to the list seems impossible. Yet localization can boost your app revenue by 30–100%.
Common indie developer concerns
I can't afford professional translators
AI translation: the same project for under €15 in 10 languages
Traditional: €0.10-€0.25 per word → a 5,000-word app = €500-€1,250 per language
What about quality?
AI translation has evolved dramatically. Modern models understand context and app terminology.
