Mobile apps

Overview

Mobile apps are essential tools for connecting with users, streamlining operations, and unlocking new revenue streams. At A2ZTECH, we deliver bespoke mobile app development services for businesses looking to launch, scale, or improve their digital products.

We specialise in both native (iOS & Android) and cross-platform development (Flutter, React Native), creating apps that are fast, reliable, and built for long-term growth. Whether you’re building an MVP or a full-scale product, we provide design, development, testing, and support — all under one roof.

Our experience spans industries including health, education, leisure, and B2B services. Every app is crafted with performance, usability, and scalability in mind.

The process

Our mobile app development process starts by understanding your audience and goals. We then move through UX/UI design, agile development sprints, and iterative testing. We also help get your app live in the App Store or Google Play. The result is a beautifully crafted, functional app that keeps users coming back — and adapts as your business grows.

FAQs

What prospects usually ask.

  • Native or cross-platform — which should we choose?

    Cross-platform (React Native or Flutter) is the right default for most business apps — one codebase, shorter timeline, lower cost, and modern frameworks are now close enough to native that users won't tell the difference. Go native (Swift / Kotlin) when you need deep platform integration like ARKit, advanced background processing, low-latency audio, or you're shipping at the kind of scale where the small performance edge meaningfully changes the product.
  • How long does it take to build a mobile app?

    A focused MVP — single platform or cross-platform, with three to five core flows — typically takes three to four months from kickoff to App Store submission. A full production app with backend, multiple user roles, integrations, and polish is more like six to nine months. We always ship incrementally, with a usable internal build in the first six to eight weeks.
  • How much does a mobile app cost in the UK?

    A cross-platform MVP usually lands between £30,000 and £80,000. A full production app with custom backend, multiple roles, third-party integrations, and ongoing iteration is more like £80,000–£250,000. The biggest cost drivers are backend complexity and integration count — not the mobile UI itself.
  • Do you handle App Store and Google Play submission?

    Yes — we manage the full submission process for both stores: developer accounts, certificates and provisioning, store listings, screenshots, privacy declarations, and the back-and-forth with reviewers when something gets flagged. Both stores are yours from day one — we publish through your accounts, never under ours.
  • Who owns the source code, accounts, and assets?

    You do. Source code lives in repositories you own, the App Store and Google Play accounts are registered to your business, and any design files and brand assets are yours. We don't lock you in to anything proprietary, and the codebase is portable to another developer if you ever need to move on.
  • What does ongoing app maintenance involve, and what does it cost?

    Maintenance covers OS-version updates (iOS and Android both ship breaking changes annually), third-party SDK upgrades, dependency security patches, server / backend operations, and bug fixes for issues that surface in the wild. For a typical production app, expect £1,500–£5,000 a month depending on scope, plus separate scoping for new features.
  • Can the app integrate with our existing systems and backend?

    Yes — most of the apps we build talk to existing systems via REST or GraphQL APIs. If you don't already have an API surface, we can build one alongside the mobile app. We've integrated apps with Stripe, GoCardless, HubSpot, Salesforce, Microsoft 365, custom ERPs, and a long list of less common internal systems.
