Visual aesthetics from specific cultures are popular globally, but apps focusing on them often cater primarily to local users. Build a photo and video app offering filters and effects inspired by Korean style, but optimized for other cultures.
Include presets for different skin tones, lighting conditions, and cultural preferences. Add tutorials on achieving the look.
Monetize through app sales, premium filters, or subscriptions.
Start with a small set of filters and effects for one non-Korean audience. Gradually expand to more cultures.
The risk is cultural appropriation backlash—ensure respectful collaboration with creators from the cultures you're adapting.
