Mobile App Development
Mobile is where your customers are. Cosarn Technologies develops intuitive, high-performance mobile applications for businesses, NGOs, and government agencies across Uganda and East Africa. From simple utility apps to complex multi-role platforms, we handle design, development, testing, and deployment — so you can focus on your business while we build the technology that powers it.
Why Your Business Needs a Mobile App
A mobile app puts your services directly in your customers’ hands — available 24/7, fast, and personalised. In Uganda, where mobile usage dominates, an app gives you a powerful competitive edge.
- Reach customers directly on their smartphones
- Works offline — no internet required for core features
- Push notifications keep users engaged and informed
We develop Android and cross-platform mobile applications using React Native, ensuring your app works seamlessly across devices with a single codebase. From UI/UX design and prototyping through to Google Play Store submission, we manage the entire development lifecycle — delivering apps that are fast, secure, and built to scale with your organisation.
We build primarily for Android — the dominant platform in Uganda — using React Native for cross-platform development, meaning your app runs on both Android and iOS from a single codebase. We also handle Google Play Store submission and setup.
A simple utility app typically takes 4–8 weeks. More complex apps with multiple user roles, backend integrations, and custom features take 2–4 months. We provide a clear project plan and milestone timeline before development begins.
Yes. We build offline-first functionality into apps where required — essential for Uganda where internet connectivity can be inconsistent. Core features work offline and data syncs automatically when the connection is restored.
Absolutely. We integrate mobile money payment gateways including MTN Mobile Money and Airtel Money directly into your app — enabling seamless in-app payments for your customers without leaving the application.
