Choosing the Right Technology
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.
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.
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.
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.
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.

FAQ
For mid-sized and enterprise projects, cost is driven mainly by integration complexity: legacy systems, internal APIs, SSO, and compliance requirements, not just the app's UI. Use the estimator above for a number based on your specific systems and requirements.
Senior developers cost more because they reduce delivery risk and improve speed.
They bring:
- Faster integration into complex codebases
- Fewer architectural mistakes
- Less supervision required
- Better long-term stability in enterprise environments
In most cases, they reduce total project cost over time
It depends on integration scope more than app size. A standard project usually needs 2-4 developers plus a backend engineer; larger initiatives with multiple integrations, security requirements, or parallel workstreams typically require a full dedicated mobile development team, including QA.
Yes, KMP is well suited to enterprise apps precisely because it reduces long-term maintenance cost. Sharing business logic across iOS and Android means fewer inconsistencies between platforms and lower cost each time you update core functionality, which matters more the longer an app stays in production.
Both are common for mid-sized and enterprise clients. Team augmentation works well when you have internal engineering capacity but need specialized mobile or KMP expertise. A fully outsourced team is a better fit when you need a dedicated group to own delivery end-to-end, especially when internal teams are already at capacity.
Yes, this is standard for our mid-sized and enterprise engagements. Tell us about your existing infrastructure, compliance needs (e.g. healthcare or fintech regulations), and integration requirements in the estimator, and our team will factor this into the scope and quote.
Yes, after you submit the form, our tech leads will follow up with a scoped estimate covering budget range, team composition, and timeline, suitable for internal planning and approval processes.
