A mobile app development company that picks native or cross-platform to fit your app.

A mobile app development company designs, builds, tests and publishes applications that run on smartphones and tablets, across iOS (Apple) and Android (Google). That covers the app itself, the screens people tap, and the back end behind it: the server, database, authentication, payments and push notifications that make the app actually work. It also usually includes getting the app through App Store and Google Play review and keeping it running as the operating systems change.

Mobile apps are built either natively, in Swift for iOS and Kotlin for Android, or cross-platform, in a framework like Flutter or React Native where one codebase ships to both stores. A good mobile app development company chooses the approach that fits your app rather than defaulting to one. Avaib has built mobile software since 2004, across more than 600 projects, with senior specialists in both native and cross-platform development.

It depends on your app. Cross-platform, using Flutter or React Native, is usually the right call when you need to be on both iOS and Android and the app is mostly screens, forms, data and standard flows, because one codebase keeps build and maintenance cost close to half and keeps both stores identical. It is ideal for MVPs and fast-moving products.

Native, using Swift and Kotlin, is the better choice when the app leans hard on the camera, sensors, AR or heavy graphics, needs every bit of platform performance, or must adopt brand-new OS features the day they ship. Because we build both, we recommend the approach that fits your app, and sometimes that is a mix, rather than pushing whichever one we happen to sell.

For cross-platform work we build in Flutter (Dart) and React Native, shipping a single codebase to both iOS and Android. For native work we build iOS in Swift and SwiftUI and Android in Kotlin and Jetpack Compose, for the apps that need maximum platform performance and the newest OS features.

Around the app we build the back end it depends on, the API, database, authentication, payments and push notifications, and we work with the store tooling (App Store Connect, Google Play Console) and CI-CD to ship and update reliably. Everything is tested on real iPhones and Android devices by a dedicated QA department.

Yes, and it is one of the most common jobs we are called in for. Whether the app is a janky hybrid build, an abandoned codebase, or stuck on an old framework nobody can maintain, we start with an honest assessment of its real state rather than reaching straight for a rebuild.

From there we stabilise it, fix what is failing, and where it makes sense re-platform it onto a steady, supported foundation, then get it back cleanly through App Store and Play Store review and up to current OS versions. A full rewrite is a last resort, not our opening offer.

Both, and this is where a lot of mobile projects come unstuck. An app is only as good as the server it talks to, so we build the API, the database, the authentication, the payments and the push notifications as one connected product with the app, by senior people who own the whole picture.

That means the business logic and integrations are handled properly, not left half-built, so what you get is a complete, working application rather than attractive screens with nothing behind them.

It depends on the scope and the approach, since a cross-platform MVP is very different from a pair of fully native apps with heavy back-end and device features. That is why we scope the work clearly up front and give you a fixed, plain-English quote before any development starts, so there are no open-ended surprises. Choosing cross-platform where it fits is often the single biggest cost saving, because you fund one codebase instead of two.

Our senior mobile engineers work at a cost-effective rate of around USD 25 per hour, the same capability Australian, US, Canadian and Middle-East firms charge a fortune for, and AI-accelerated delivery helps get you there faster. After a short conversation we will send you a free, no-obligation written estimate with a clear scope.

You own everything. We hand you the full source code, the data and the documentation in mainstream, well-supported mobile technology any capable team can maintain, and we publish the app under your own Apple and Google developer accounts. There is no lock-in to us and no dependence on a single developer, and you can never be shut out of your own product.

We deliberately avoid niche frameworks and undocumented structures that only we can run. You stay with Avaib because the work keeps delivering value, not because you are trapped.
