Mobile App Development South Africa | iOS and Android Apps
South Africa’s smartphone market has reached a critical mass. With over 35 million smartphone users (GSMA, 2024) and mobile internet usage at 91.2% of all internet sessions (DataReportal), a well-designed mobile app gives your business a direct, persistent channel to your customers’ most personal device.
Digital 4 Jesus develops custom mobile applications for South African businesses — from straightforward utility apps to complex multi-platform enterprise solutions. Our development team combines technical excellence with deep digital marketing expertise, ensuring your app is not only functional but designed to drive measurable business results.
Our Mobile App Development Services
Android App Development
Android holds approximately 85% of South Africa’s smartphone market share (StatCounter, 2024), making it the essential platform for most SA businesses. We develop native Android applications using Kotlin and Java, as well as cross-platform apps using React Native that deliver native-quality experiences on Android devices. Learn more about Android development.
iOS App Development
iOS users typically represent higher-income demographics and have significantly higher in-app purchase rates than Android users. We develop native iOS applications using Swift and cross-platform apps that perform natively on iPhone and iPad. Learn more about iOS development.
Cross-Platform App Development
Using React Native and Flutter, we build apps that run natively on both iOS and Android from a single codebase — reducing development cost by up to 40% while delivering excellent performance on both platforms. Cross-platform development is ideal for most business applications and consumer apps.
Progressive Web Apps (PWA)
Progressive Web Apps offer app-like experiences through a browser — no App Store required. PWAs work on all devices, are discoverable by search engines, and can be installed directly from the browser. They are an excellent option for businesses that want mobile app functionality without the complexity of native development.
Backend and API Development
Great apps require robust backends. We build secure, scalable REST APIs and backend systems to power your mobile app — handling user authentication, data storage, push notifications, third-party integrations, and business logic that powers your app’s functionality.
App Store Optimisation (ASO)
Getting your app found in the App Store and Google Play requires the same strategic approach as SEO for websites. We optimise app store listings — title, description, keywords, screenshots, and ratings strategy — to maximise organic downloads from both stores.
