    Common questions

    How much does it cost to build an app?

    It depends on scope. A simple MVP with a few core screens costs far less than a full product with custom design, a backend, payments, integrations and apps for both iOS and Android. Our app development cost guides break down typical price ranges and what drives them.

    Should I build for iOS, Android or both?

    Many teams start with the platform their customers use most, then expand. Cross-platform frameworks like Flutter and React Native let one codebase ship to both stores, which usually lowers cost, while native Swift and Kotlin can make sense for apps that lean heavily on device features or performance.

    What should I look for in an app development company?

    Look for shipped apps in your category, references you can call, a clear process for design, testing and launch, and a plan for maintenance after release. Ask who owns the code and how handover works if you later move development in-house.
