Mobile App Development

Mobile app development for iOS and Android, from idea to App Store and Google Play

We design and build mobile apps people enjoy using. With a cross-platform approach, one team ships to both iOS and Android from a single codebase, which cuts time and cost while keeping performance and polish high. You can hire mobile app developers from SimpleApp to join your team, or outsource the whole app, from the first sketch to store launch and support, with weekly demos and full ownership of the source code.

FAQ

Mobile App Development questions

Do you build for both iOS and Android?

Yes. We usually build both from one cross-platform codebase, or go native when a project needs it.

Should my app use React Native or Flutter?

Both build good iOS and Android apps from one codebase. We pick based on your team, your existing code and the features you need. React Native suits teams that already use JavaScript or React. Flutter suits apps with a highly custom design. We explain the choice before you commit.

How long does it take to build a mobile app?

It depends on the number of screens, the integrations and the backend. A focused first version often takes a few months. After a short discovery we give you a milestone plan with dates, and you see a working build every week.

How much does a mobile app cost?

Cost depends on scope, so we do not quote before we understand it. Share your idea on the contact page and we reply within one business day with questions, a rough scope and a free, no-obligation estimate.

Do you help publish the app?

Yes. We prepare store listings, handle submissions to the App Store and Google Play and support you through review. The Apple and Google developer accounts stay in your name, so you own the app.

Can I hire mobile app developers or outsource the whole app?

Yes. You can outsource the full project with fixed milestones, or have our developers join your team. Either way you get weekly progress updates and tested code.

Will I own the source code?

Yes. Full source code and IP ownership transfers to you, with documentation, and there is no lock-in.

Do you maintain the app after launch?

Yes. We fix bugs, monitor crashes, update the app for new iOS and Android versions and add features as your business grows.
