Mobile Apps That Users Actually Love

For most businesses, cross-platform development with React Native or Flutter is the right choice — it delivers 90–95% of native performance at roughly 60–70% of the cost, because you maintain one codebase for both iOS and Android. Native development (Swift for iOS, Kotlin for Android) makes sense when you need access to cutting-edge platform features before they reach cross-platform frameworks, require extreme performance (e.g. real-time video processing or complex gaming), or have a very large existing codebase on one platform. We will advise you honestly based on your specific requirements — not on which approach maximises our project value.

A focused MVP typically takes 8–12 weeks from discovery to App Store submission. A full-featured app with both platforms, custom backend and complex integrations typically takes 16–24 weeks. Enterprise apps with security requirements, legacy integrations and multiple user roles can take 6–12 months. Timeline is heavily influenced by the clarity of your requirements at the start — a detailed specification dramatically accelerates development. We provide a week-by-week project plan after the discovery phase.

Yes — full source code ownership is transferred to you upon final payment. We never retain any IP over work we build for clients. You will receive all repositories, assets, design files, API credentials and documentation. You are free to take the code to any other developer or agency in the future, though we hope you will continue to work with us for ongoing development and support.

We handle the entire App Store and Google Play submission process — screenshots, metadata, app icon, privacy policy, age ratings and the review process itself. You will need an Apple Developer account (£99/year) and a Google Play Developer account (one-time £25 fee), both registered in your name. We advise on this early in the project. Apple's review process typically takes 24–72 hours; Google Play typically takes a few hours to a day. We manage any rejection feedback and resubmission as needed.

Yes — we regularly take on existing apps for feature development, performance improvement and redesign. We start with a code review to understand the existing architecture, identify technical debt and assess the state of the codebase. We then provide an honest assessment of whether it is more cost-effective to build on the existing code or undertake a targeted rebuild of specific modules. Some codebases we inherit have been well-maintained; others require significant remediation before new features can be added safely.

Every project includes a post-launch support period (30–90 days depending on package) covering bug fixes, monitoring and minor adjustments. After that, we offer ongoing development retainers for teams that want to continuously improve their product — adding features, optimising performance, responding to user feedback and adapting to new OS versions. Mobile apps are living products; the most successful ones are continuously iterated based on real user data.

Yes — we build full-stack. Every mobile app needs a backend: user authentication, data storage, push notifications, payment processing and API integrations all require server-side infrastructure. We design and build this in-house using Node.js, PostgreSQL, Firebase, AWS or GCP depending on your requirements. Having design, mobile development and backend under one roof eliminates the coordination overhead and finger-pointing that can plague projects split across multiple agencies.

Security is built in from the start — not bolted on afterwards. We implement encrypted data storage, secure API communication (HTTPS/TLS), certificate pinning, biometric authentication, input validation and principle-of-least-privilege access controls. For GDPR, we implement data minimisation, consent management, the right to erasure and appropriate retention policies. For healthcare apps, we additionally comply with NHS Digital guidelines and DTAC standards. We can provide penetration testing via our security partners where required.
