All Mobile App Developers in South Korea
HEYHICOMPANY
5(1 review)At HeyHi Company, we design UX/UI that solves real business problems — not just screens that look good. Our process runs from user research and information architecture to wireframing, UI design, and developer handoff, with a separate planning (STEP 1) phase up front to reduce risk before design begins. We specialize in complex, high-stakes interfaces: B2B SaaS platforms, multi-tenant dashboards, and enterprise services. That depth comes from delivering for clients like CJ ENM and Deloitte, and it's why our work earned Korea's 2024 ICT Award Grand Prize (Minister's Award) and a 2025 GDWEB Gold. What you can expect: a research-backed rationale for every decision, clean Figma files ready for development, and a team that embeds with you from day one. With offices in Seoul and Bangkok, we work fluently with both Korean and international clients.Looking for work in Mobile AppLocated in Seoul, South Korea (+1)From €1,000 for Mobile AppWorks in multiple industriesSpeaks English, Japanese(+1)11-50 membersPlusLabs
