Building separate native iOS and Android apps roughly doubles engineering effort compared to a single cross-platform codebase, because you're maintaining two implementations of every screen and every piece of business logic. Flutter is a practical middle ground: one codebase ships to both the App Store and Google Play, which is why it's the default choice for most MVP-stage mobile products rather than a compromise.

For products that genuinely need deep platform-specific capability — heavy use of a phone's hardware in ways only native APIs expose well — native development can be worth the extra cost. For most business apps, it isn't necessary.

Authentication, a handful of core screens, and basic data storage form the baseline of almost any app and are relatively inexpensive to build well. Cost climbs with real-time features (live chat, live video, live location tracking), offline support (an app that has to work correctly with no connection and sync later), and payment or subscription handling.

A fitness platform built with Flutter, Firebase, and Agora for real-time video calling — the kind of build that includes authentication, real-time chat, and video — is a good reference point for mid-complexity mobile app scope; that class of app is realistic to ship as a production MVP within a few months, not a year.

Fixed-price mobile app work starts from USD 500 for the smallest scoped builds and scales with the number of screens, integrations, and real-time or offline requirements. Hourly billing runs USD 25–45/hr with a 10-hour minimum. A standard MVP-scope mobile app typically takes 3–6 months from kickoff to store submission once you include app store review time, which is worth planning around if you have a launch date to hit.
