South Korea-specific requirements to plan for

Payment methods customers in South Korea expect: KakaoPay, Naver Pay, Toss Payments, KG Inicis and Samsung Pay.
Interface and content languages: Korean.

How the quote is scoped

These factors affect the work involved:

Number of unique screen templates
Third-party SDK integrations (payments, maps)
Offline sync architecture
Backend complexity

Share your budget in KRW or USD. The schedule, payment milestones, external charges and support terms are agreed in writing before work starts.

Review and handover

Test the agreed device matrix, account recovery, permission denial, offline behavior and API errors. Store submission can be in scope; approval timing is decided by the store. Source-code and asset ownership, licences, account access and ongoing support are set out in the project terms.

How long does a mobile app project take?

Will the project follow PIPA in South Korea?

The build is planned around the Personal Information Protection Act (PIPA): consent capture on forms, a clear privacy notice, data minimisation and suitable hosting. PIPA is one of the strictest privacy laws in Asia — separate consents are often needed for marketing and third-party sharing. Final legal wording should be checked by your legal adviser.
