Should you build a native iOS app or a cross-platform app?
Build native iOS with Swift when the app depends on deep Apple features, top performance or a premium iPhone audience. Choose cross-platform with Flutter or React Native when you need iOS and Android quickly from one codebase. Stack18 builds both and recommends based on features, audience and budget.

Discover
We map today’s process, systems and data for native iOS development, Apple ecosystem features and offline and sync, talk to the people who run it and agree the baseline for crash-free sessions and app Store rating, so progress is measured from week one.
Design
We design the flows, roles, approvals and integrations for native iOS development and Apple ecosystem features, and review a clickable prototype or technical design with the people who will use it before anything is built.
Build
We build in weekly demos, starting with native iOS development, then Apple ecosystem features and offline and sync. Each release is tested on your own data and passes a human approval gate before the next begins.
Launch
We migrate data, train your team and support go-live. After 30 days we review crash-free sessions and app Store rating against the baseline and agree what to extend next.
How much does iOS App Development cost in India?
