FAQs

Mobile Apps questions answered.

Should I build a native app or a cross-platform app?

Native apps are built separately for iOS and Android and offer the deepest access to device features and platform polish. Cross-platform apps share one codebase, which usually lowers cost and speeds delivery. The right choice depends on your features, performance needs and budget, and we recommend one after discovery.

Do you build both iOS and Android apps?

Yes. We build for iPhone and iPad as well as Android phones and tablets, either as separate native apps or from a shared cross-platform codebase, and we test on real devices across screen sizes and OS versions.

How much does it cost to develop a mobile app?

Cost depends on the platforms, number of screens and features, backend work, integrations and design depth. A focused first version costs less than a full-featured product. We scope the work during discovery and estimate against a defined feature list.

How long does it take to build a mobile app?

Timelines follow scope and platform choice. A focused MVP takes less time than an app with a custom backend and many integrations. App store review adds a short period at the end, which we plan for in the schedule.

Will you publish the app to the App Store and Google Play?

Yes. We prepare store listings and assets, build release versions, handle submission and respond to review feedback. Store accounts should be owned by your company, and we guide you through setting them up.

Can you update or maintain an existing app?

Yes. We can review an existing app, fix bugs, update it for new OS versions, improve performance and add features, as long as we can access the source code or can agree a plan to rebuild it.
