Choosing the Right Technology

Native (iOS / Android)

Best when performance, deep OS integration, or platform-specific UI is critical. Typically the most expensive option since iOS and Android are built and maintained separately, but it gives you full flexibility and access to the latest capabilities.

Kotlin Multiplatform Technology Logo
Kotlin Multiplatform (KMP)

Our core specialty. KMP lets you share business logic across Android and iOS while keeping native UI on each platform. It's an excellent choice for businesses looking for long-term scalability. If you're evaluating Kotlin Multiplatform development, our team has been building production KMP apps since before it became an industry standard.

Compose Multiplatform

For teams looking to share even more code, Compose Multiplatform enables a shared UI while maintaining native capabilities where needed. CMP can significantly reduce development effort, and it's especially valuable for organisations investing in long-term product development. We can also advise on Compose Multiplatform development for sharing UI as well as logic.

Aetherius Solutions | Flutter Logo
Flutter

Flutter uses a single codebase to build applications for both Android and iOS, making it a popular option for businesses that prioritise rapid development and a consistent user interface across platforms. It works particularly well for MVPs, consumer apps, and design-focused products that benefit from fast iteration. Explore our Flutter app development services.

Aetherius Solutions | React Logo
React Native

A solid choice if your team already works in JavaScript/TypeScript, or you want to move fast with a large open-source ecosystem. React Native allows teams to build Android and iOS applications using JavaScript and React. Its large community and mature ecosystem make it a practical choice for many commercial applications. See our React Native app development services.

Why Estimate Your Project Before Hiring Developers

Getting a cost and scope estimate before you hire mobile app developers protects you from two common mistakes: underestimating complexity (and running out of budget mid-project), or overbuilding your team before you actually need it.

An upfront estimate also makes it much easier to decide how to staff the project: whether that means bringing in dedicated developers to extend your current team, or choosing to fully outsource mobile app development to a team that owns delivery end-to-end.
