Service

Mobile apps built to actually get used, not just published.

From your first wireframe to a live listing on the App Store and Google Play, we design, build, test and support the mobile app your business needs — as one team, not a relay of subcontractors.

Most mobile projects don't fail because of bad code. They fail because the wrong scope was signed off in week one, or because nobody thought about what happens after launch. At Mont6 we treat app development as a single, connected process rather than a series of handoffs: the same people who map out your user flows are in the room when we're debugging a build six months later. That continuity is what keeps timelines honest and budgets predictable, and it's a large part of why South African businesses come back to us for their second and third apps rather than shopping around each time.

Native or cross-platform — decided by your app, not by habit

Every mobile engagement starts with the same question: does this app need to be two separate native codebases, or can one React Native codebase serve both iOS and Android? We don't default to either answer. Apps that lean on standard interface patterns — booking flows, catalogues, account management, most internal tools — are usually better served by a shared codebase, because it halves the ongoing maintenance burden without costing you anything in feel or performance. Apps that depend on deep camera work, background processing, complex animation, or matching a very particular platform convention tend to justify native development instead. We'll walk you through that trade-off in plain terms before any commercial proposal is drawn up, and we'll say so plainly if cross-platform is the cheaper, equally capable option — even though native projects are usually the larger engagement for us.

A process built around checkpoints you can actually see

We break every build into short, visible phases rather than one long development sprint that only resurfaces at the end. Analysis and scoping come first, so you know what you're paying for before a line of code exists. Wireframes and a clickable prototype follow, so the app's structure gets tested while it's still cheap to change. Development then happens in short cycles, with builds you can install and try on your own device throughout — not just at the finish line. That rhythm means problems get caught while they're still inexpensive to fix, and it means you're never left waiting weeks for the next real update on where your budget went.

Getting an app approved, not just built

A working app and an approved app are two different things. Apple, Google and Huawei all reject submissions for reasons that have nothing to do with code quality — inconsistent screenshots, missing privacy disclosures, a permission prompt that trips up a reviewer testing from a fresh install with no existing account. We build store compliance into the project from the start rather than treating it as a final hurdle, which is a large part of why the apps we submit typically clear review on the first or second attempt. If your app needs to reach a private or enterprise audience instead of a public store listing, we handle that distribution path too.

What happens after your app goes live

Launch is the point where most agencies disappear and most support contracts start. We stay involved: monitoring crash reports and performance, applying operating system updates before they break something in production, and building the next round of features once you can see how real users are actually using the app. Because the team that built your app is the same team maintaining it, there's no ramp-up period every time you need a change — no explaining the codebase to someone new, no re-discovering decisions that were made a year earlier by someone who's no longer on the project.

Whether you're validating an idea or replacing an old app

This service works the same way whether you're a founder validating a first version on a tight budget, or an established South African business replacing an app that's become slow and expensive to maintain. What we ask for up front is the same in both cases: real clarity on who the app is for and what it needs to let them do, even if the exact feature list is still taking shape. Replacing an existing app comes with its own considerations — migrating user accounts and data without downtime, keeping your existing store listing and reviews intact rather than starting from zero, and deciding what from the old app is worth keeping versus what was actually the reason it needed replacing in the first place. We'll walk through that audit with you before any rebuild work starts.

What's included

  • Native iOS and Android development, or a single React Native codebase
  • Backend, API and database work to support the app
