Mobile App Development
iOS and Android apps built with Swift, Kotlin, React Native, and Flutter, including real-time, location-aware apps like Ubii, a ride-hailing platform we built for a client. From idea to App Store.
We build the app, the platform,
and the hardware behind it.
From concept to App Store — KSE Labs designs and develops mobile apps, web platforms, and the custom hardware they run on. We built KeeLess, Ubii and ZeroForm end to end.
Multiple products live on the Apple App Store and Google Play, built and maintained by the same team.

§ 01About Us
We're a software engineering company
KSE Labs (Pty) Ltd is a software engineering company based in Johannesburg, South Africa. We don't just take mobile application and web platform briefs and execute them, we build end to end: a ride-hailing app's real-time backend, a privacy-first AI platform, and the custom circuit boards and proprietary communication protocol behind an access control system we engineered in-house, hardware included.
That range is deliberate. Whether you need an iOS app developer, an Android app developer, or a full-service software development company in South Africa that can take a build from idea to custom hardware, KSE Labs has shipped it before. Multiple apps live on the Apple App Store and Google Play Store, across industries from beauty to transportation to food tech, all built and still maintained by the same team.
We build for clients, and we ship products of our own. That second part matters to the first: running our own software means we know what a build costs to maintain years after launch, not just what it costs to ship. See how we approach the harder builds →

§ 08Testimonials
What Our Clients Say
SK
Sandile K.
★★★★★
"We went through two other devs before KSE Labs and both ghosted us mid-build. These guys actually shipped — booking, payments and staff scheduling all working before our salon's first month-end. Took longer than the original quote because we kept adding features, but they were upfront about that instead of just padding the invoice."
MN
Mpho N.
★★★★★
"We were replacing physical access cards across the whole estate, and I was bracing for weeks of residents struggling with a new system. The KeeLess install team handled onboarding directly, and revoking a lost credential now takes minutes instead of waiting for someone to physically hand back a card. Took a bit of adjusting for our older residents, but support sorted out every issue we raised."
TM
Thabo M.
★★★★★
"Building a ride-hailing app with live tracking and driver payouts was way more involved than we expected, and there were a couple of rough weeks getting the matching logic right. KSE Labs stuck with it, explained the trade-offs in plain language, and Ubii has been running reliably since launch."
§ 09From the Lab
Case Studies & Blog
A deeper look at how we build, and what it actually costs.
Reinventing Access Control with KeeLess and KeeChain
Custom controller hardware, the proprietary KeeLink protocol, and a digital wallet layer, all built in-house. A look inside our most demanding product.
Read the case studyWhat Does a Mobile App Cost in South Africa in 2026?
Real numbers, not guesswork: what actually drives the quote you get, why two studios can price the same app R200,000 apart, and where founders overspend.
Read the breakdown§ 10Questions
Before You Ask
The four things people email us about most, answered honestly.
How much does it cost to build a mobile app in South Africa?
Mobile app development in South Africa typically ranges from around R50,000 for a simple app to R500,000+ for a complex, feature-rich build. What moves the number is scope: real-time features, payments, custom hardware and third-party integrations cost more than screens do. We break the maths down properly in What Does a Mobile App Cost in South Africa in 2026? Every quote is free and scoped to your actual project.
Does KSE Labs build apps for both iOS and Android?
Yes. We build native and cross-platform mobile applications that perform well on both operating systems. Which approach suits you depends on the build — we cover that trade-off in Flutter vs React Native for SA Startups.
How long does it take to develop a mobile app?
Timelines vary with complexity. A typical mobile app takes 8–16 weeks from design to launch, covering discovery, UI/UX design, development, testing and App Store submission. Builds with custom hardware or real-time systems run longer, and we will say so up front rather than after you have signed.
What services does KSE Labs offer?
Mobile app development for iOS and Android, web application development, UI/UX design, API and backend development, cloud infrastructure, performance optimisation, and ongoing maintenance and support. We also design and build the embedded hardware some of those systems run on — see our full portfolio.
