Rowan Software designs, builds, ships and supports high-quality mobile apps. One shared C# codebase, native results on every phone, and automated pipelines that get new features to your customers faster.
Whether you're starting from a sketch or inheriting a codebase, we cover design, development, release and the long tail of support after launch.
Bring us an idea and we'll turn it into a polished, native-feeling app for iPhone and Android. We handle the whole journey so you don't have to manage the build.
Microsoft stopped supporting Xamarin on 1 May 2024. We'll move your app to .NET MAUI and carry your existing C# code with it, so it keeps building for the latest iOS and Android.
Bug fixes, new features, SDK and OS updates, and a clear way forward for an app another developer started.
Pipelines that build, test, sign and ship your app to the App Store and Google Play at the click of a button.
Store listings, screenshots, review guidelines, signing and release management, handled for you.
.NET MAUI is Microsoft's framework for building native iOS and Android apps from a single C# project. It's the successor to Xamarin.Forms, and it compiles to real native controls, not a web view in a wrapper.
For most business apps, that means features land on both platforms at the same time, there's one set of tests and one team, and maintenance costs stay predictable.
| Separate native apps | .NET MAUI | |
|---|---|---|
| Codebases | 2 | 1 |
| Languages | Swift + Kotlin | C# |
| New feature | Built twice | Built once |
| Native UI & APIs | Yes | Yes |
| Shares code with .NET backends | No | Yes |
A look at some of the apps we've designed and built ourselves.
A web browser for people with dyslexia, dyspraxia and visual stress. It tints every page in a colour that suits you, opens articles in a calm reader with dyslexia fonts, and reads them aloud.
Like a colour overlay for the real world. Point the camera at a letter, menu or worksheet and the words appear in a font, size and colour that suit you, or are read aloud. Text is read on the phone, so nothing is uploaded.
Turns an old, unused phone into a low-cost vehicle tracker. Leave it in the car and follow it live from your own phone or any browser, for one vehicle or a whole fleet, with no expensive hardware to fit.
You'll see working software early and often, not just a big reveal at the end.
A short call to agree what "done" looks like, what it will take, and what to build first.
Regular builds you can install on your own phone, so feedback happens while it's cheap to act on.
Real devices and real edge cases are covered before anything reaches an app store review queue.
Store submission, release management, and a plan for updates after version 1.
Turn an idea into a version 1 that's ready for the stores, without building an in-house team first.
Apps for your customers or your staff, such as bookings, job tracking or loyalty, that fit how you already work.
Specialist .NET MAUI help to add capacity, unblock a release or set up CI/CD.
A safe, planned route off Xamarin before store requirements leave your app behind.
.NET MAUI (Multi-platform App UI) is Microsoft's framework for building native iOS and Android apps from a single C# codebase. It's the successor to Xamarin.Forms.
Microsoft ended support for Xamarin on 1 May 2024, so Xamarin apps no longer get updates for new iOS and Android versions. Migrating to .NET MAUI keeps your app supported and buildable for the latest store requirements, and most of your existing C# code can come with it.
MAUI is our speciality, but we also work with native Swift on iOS and Kotlin on Android, and we'll recommend whatever suits your app and team best.
Yes. We can pick up an existing codebase to fix bugs, add features, update dependencies and SDKs, or move it to a cross-platform setup.
Yes. We handle store submissions, listings, signing and release management, and can set up automated pipelines so future releases are a single click.
We offer ongoing support and maintenance, from the yearly iOS and Android updates and bug fixes to new features, so your app keeps shipping.
Yes. We're based in East Yorkshire and work with clients across the UK, remotely or in person.
Tell us what you're working on. We'll get back to you with honest next steps, even if that means pointing you somewhere else.
