Mobile App Development Services
Apps people keep on their home screen.
NetOfficials designs and builds iOS and Android apps for B2B companies, native in Swift and Kotlin or cross-platform in Flutter and React Native. One team takes your app from a written scope to both app stores, then hands over the source code, documentation and IP. Apps for both platforms from one shared codebase are covered by our cross-platform app development services.

Native or Cross-Platform?
Both approaches ship real apps. The better fit depends on how much you need device-specific features, how soon you must reach both platforms, and how your team will maintain the app.
Cross-platform is usually the better fit when
- You need iOS and Android at the same time
- Your app is mostly forms, lists and content
- One team will maintain a single codebase
- Budget and timeline favour sharing code
| Consideration | Cross-platform | Native |
|---|---|---|
| Platforms covered | iOS and Android from one codebase | One platform per codebase |
| Device features | Most through plugins | Full, immediate access |
| Look and feel | Shared design with tweaks | Fully platform-native |
| Time to both stores | Usually shorter | Longer, two codebases |
| Maintenance | One codebase to update | Two codebases to keep in step |
| Performance ceiling | Good for most business apps | Best for demanding graphics |

How We Choose the Right Mobile Stack
We recommend technology for your project and your team's future, not for our convenience. Three questions guide every choice.
Will it handle your load?
We size the design for your expected users, data and growth, so it does not need rebuilding when the business grows.
Will it fit your systems?
We check how the stack connects with the tools, databases and partners you already rely on before we commit to it.

Mobile App Development FAQs
Should I build a native or a cross-platform app?
Native suits apps that rely heavily on device features or top performance. Cross-platform suits teams that need iOS and Android together from one codebase. We compare both against your requirements during discovery.
Do you publish the app to the App Store and Google Play?
Yes. We prepare the builds, store listings and submission, and hand over the source code at release.
Who owns the app and its source code?
You do. IP assignment is confirmed in the contract before the build begins, and you receive the full source code and documentation at handover.
Can you build the backend and APIs as well?
Yes. The same team builds the APIs and cloud services your app depends on, so the app and its backend stay aligned.
How do I follow progress?
Work is tracked in Jira, a named delivery lead owns your project, and every sprint ends with a demo for your review.
Can you extend or take over an existing app?
Yes. We review the existing codebase first, then plan the changes in a written scope you approve.
