A mobile app built for how your business actually works.
Not a showcase app. Not a template. A custom Android or iOS app that solves a specific operational problem — works offline, runs in the field, and does exactly what your business needs without everything it doesn't.
Good for
- Field service businesses needing digital job cards, inspection forms, or proof of delivery
- Businesses with paper-based processes that cost hours every week
- Client-facing portals, booking tools, or product catalogues that need to work on a phone
- Teams working in areas with unreliable signal who need offline capability
Custom apps for real business operations.
Android & iOS
Apps built for Android and iOS — the two platforms your customers and field teams actually use. No cross-platform shortcuts that create problems later. Built properly for the platform it runs on.
Offline-capable field apps
Inspection forms, job cards, site reports, toolbox talks, proof of delivery — apps that capture data in the field and sync when signal returns. Designed for the reality of South African infrastructure, not a fibre-connected office.
Business process apps
Asset tracking, multi-user job management, client portals, booking systems, and custom operational dashboards. Built around your actual workflow — not a generic platform you have to adapt to.
Scoped to the problem. Nothing more.
Most app development quotes come back bloated — features you don't need, platforms you don't use, and a maintenance contract attached. We scope to the actual operational problem first. What is the process that's costing you time or money right now? We build the minimum that solves that — properly, with the right architecture — and quote it at a fixed price before any work starts. No retainers, no lock-in, no proprietary platform that traps your data.
Quoted per project.
What drives the price: number of screens, whether it needs a backend/database, multi-user requirements, offline sync complexity, and whether it needs to integrate with an existing system. A simple single-user field form is at the lower end. A multi-site, multi-user system with a management dashboard is at the higher end. Every project is scoped and quoted in writing before any work starts.
What people usually ask first.
How much does it cost to develop a mobile app in South Africa?
Custom mobile apps with Horn Dev start from R15,000 for a focused, single-purpose app — for example, a field inspection form with offline capability and basic reporting. More complex apps with multiple user roles, a backend database, and a management dashboard typically range from R25,000 to R60,000+. Every project is scoped first and quoted at a fixed price — no surprises after work starts.
What drives the cost of a mobile app?
The main cost drivers are: number of screens and user flows, whether the app needs a backend server and database, how many users it needs to support simultaneously, offline sync requirements, third-party integrations (payment gateways, existing systems, APIs), and whether it needs both Android and iOS. A simple offline data capture app for a single team is fundamentally different in cost from a multi-site client portal.
Do you build for Android only, or iOS too?
Both. The choice depends on what your team and clients actually use. In South Africa, Android is more common for field staff and internal tools. iOS is more common for client-facing apps targeting a higher-income market. We'll ask about your users during scoping and recommend accordingly — or build for both if that's what the project needs.
What does "offline-capable" mean?
It means the app works without an internet connection — capturing data, completing forms, taking photos, updating records — and syncs everything to the server automatically when signal returns. This is built in from the start, not added as an afterthought. It matters especially for mining, construction, agriculture, and field service work where signal is unreliable.
Can I build my own app for my business without a developer?
No-code tools like Glide, AppSheet, and Bubble exist for simple internal apps — if your use case is genuinely simple, they may be worth trying first. But they have hard limits: offline capability is usually poor, they don't scale well, and you're locked into a monthly subscription for something you don't own. If the process you're trying to fix is core to your business, a custom app built properly is the better investment.
Do I own the app when it's built?
Yes. The source code, the design, and all the data belong to you. There are no ongoing licence fees for the app itself. If hosting is required (for a backend server), that cost is separate — we'll discuss what's appropriate for your usage volume during scoping.
Describe the problem, not the app.
The best starting point is telling us what process is costing you time right now — not a full spec. A short WhatsApp conversation is usually enough to work out whether a custom app is the right answer and what it would involve.
