Choosing web, native iOS/Android, or cross-platform

Web reaches the widest audience with the fastest iteration cycle — ideal for B2B dashboards and internal tools. Native mobile fits performance-critical, offline, or deeply OS-integrated experiences. Cross-platform frameworks trade some native polish for shared codebase speed. Kapalıçarşı shipped as a native iOS product because live market data, smooth charts, and App Store distribution matched the audience; a web-only version would not have served the same use case.

Shared backend, clear API contracts

Whether you ship one client or three, the backend should expose stable APIs with authentication, versioning, and observability. Mobile and web clients consuming the same services reduce duplicate logic. Define pagination, error shapes, and real-time needs early — retrofitting them after launch is expensive.

Design for each surface, not a shrunk desktop

Responsive web is not a substitute for mobile UX when thumbs, notifications, and offline states matter. Budget for platform-specific patterns: navigation, forms, and permissions differ. A design system helps, but allow platform adjustments instead of forcing pixel parity.

Release, stores, and ongoing operations

Mobile adds App Store and Play Store review cycles, crash analytics, and forced-update strategy. Web adds browser support matrices and CDN deployment. Both need staging environments, automated tests on critical paths, and a plan for post-launch fixes. Discuss who owns on-call, dependency updates, and OS upgrades before sign-off.

Questions to ask before you sign

Who owns the codebase and accounts? How are secrets and push credentials managed? What is the test strategy on real devices? How will analytics and feature flags be wired? Clear answers prevent handover surprises when the first production incident hits.
