What it costs
Engagements usually start with a paid scoping phase from R38,000 excl. VAT, with most app builds landing around R150k excl. VAT and scaling in phases from there. We often recommend a web platform first to prove the model, then native mobile once you've got real users, so you don't commit to the full build, or the full budget, on day one.

Why Choose Netgen For Your App
Full-Cycle App Development Services
React Native Apps for iOS and Android
Single React Native codebase deployed to both the Apple App Store and Google Play. Native module integration for camera, push notifications, biometrics, and SA-localised services. Maintained from one source rather than two separate native teams.
.NET MAUI Cross-Platform Apps
Cross-platform mobile development in .NET MAUI for clients with existing Microsoft .NET back-end systems. Shared C# codebase between mobile and backend reduces total cost of ownership and lets the same team maintain both layers.
Cross-Platform — React Native & Flutter
Full submission to the Apple App Store and Google Play Store, including provisioning, signing, screenshots, store-listing copy, and the review-feedback cycle. Apps are published under your developer account, not ours.
Backend & APIs
Robust custom backends in .NET Core or Node.js. PostgreSQL, MySQL, or SQL Server. Hosted on Azure, AWS, or local SA infrastructure depending on compliance needs.

Frequently Asked Questions About Mobile App Development at Netgen
Common questions about our React Native and .NET MAUI mobile app development services, pricing, IP ownership, and App Store submission in South Africa.
Does Netgen build iOS and Android mobile apps?
Yes. Netgen builds mobile apps for both iOS and Android using cross-platform frameworks, primarily React Native, with .NET MAUI for clients with existing Microsoft .NET back-end systems. A single codebase ships to both the Apple App Store and Google Play, which keeps development time and ongoing maintenance lower than separate native builds.
How much does a mobile app cost in South Africa?
Most full app builds at Netgen start from R150,000 excl. VAT for a complete app with backend, including iOS, Android, and the supporting REST API or cloud infrastructure. We often recommend a phased approach: a web platform first to validate the model, then mobile once real user demand is proven.
Should I build a native app or a cross-platform app like React Native?
Native apps deliver the best performance and platform-specific features such as advanced camera, ARKit, or hardware integrations. Cross-platform frameworks like React Native and .NET MAUI ship one codebase to both iOS and Android, which is faster and cheaper to build and maintain. For most South African business apps cross-platform is the right choice. The decision depends on your performance requirements, budget, and team.
Does Netgen develop with .NET MAUI for cross-platform mobile apps?
Yes. Netgen develops cross-platform mobile apps in .NET MAUI for clients with existing Microsoft .NET back-end systems, where a shared C# codebase across mobile and backend reduces total cost of ownership.
Who owns the source code after Netgen builds a mobile app?
You do. Netgen builds the mobile app as your intellectual property. There are no licence fees payable to Netgen, and you retain full ownership of the source code and the right to publish or migrate the app anywhere.
Does Netgen handle App Store and Google Play submission?
Yes. Netgen handles the full submission process to the Apple App Store and Google Play Store, including provisioning, signing, store-listing copy, screenshots, and the review-feedback cycle. Apps are published under your developer account, not ours.
Where are Netgen's mobile app developers based?
Netgen's mobile app development teams are based in Johannesburg (Randburg, Gauteng) and Cape Town (Westlake, Western Cape). Our developers are all in South Africa. No offshoring.
