We build native Android apps in Kotlin when performance or deep hardware access matters most, and cross-platform apps when you need both Android and iOS from a single codebase, faster and for less.

Native gives you full device integration and top-tier speed. Cross-platform gets a working product onto both stores sooner. The right call depends on your users, your systems and your timeline. We'll help you decide in a free discovery session before any code is written.

What do you get from our Android app developers?

Every Android project at Myth follows four clear stages, each with a tangible deliverable you can review and sign off.

  • 01

    Discovery and scoping

    What does the app actually need to do? We answer that in workshops at our Belfast or London office, mapping user journeys and agreeing the technical approach before any build work starts.

  • 02

    UX and UI design

    Our designers work to Android's Material guidelines. They account for the full range of screen sizes and densities, so the app feels right whether someone's on a budget handset or a flagship tablet.

  • 03

    Development and integration

    We build the app and connect it to your existing systems. APIs, single sign-on, databases: it all works within your current setup from day one.

How long does Android app development take?

Scope drives everything. A focused utility can reach a testable build in weeks, while full-featured products with integrations, user accounts and offline support typically take three to six months or more.

We deliver in phases. You get working builds at every milestone so you can test, gather feedback and steer the next stage.

After an initial discovery workshop, we provide a fixed-price ballpark so you know what to expect before a line of code is written. No surprises, just steady progress.

  • Phased builds, not big-bang launches
  • Working software in your hands early
  • Fixed-price ballpark after discovery

Which decisions shape your Android app project?

Explained plainly so you can choose confidently.

Native vs Cross-Platform
Screen from the LifePass case study

Native vs Cross-Platform

  • Cross-platform shares one codebase across Android and iOS, cutting build time and ongoing maintenance.
  • Choose native when you need deep hardware access or platform-specific performance that a shared codebase can't match.
  • Most projects we deliver are cross-platform in React Native, backed by a .NET Core API on Azure.
Device and Screen Fragmentation

Device and Screen Fragmentation

  • We design responsive layouts tested across the screen sizes UK users actually own.
  • Real-device testing catches issues emulators miss.
Connecting to Your Systems

Connecting to Your Systems

  • We build secure API layers linking your app to existing databases and authentication.
  • SSO, role-based access and live data sync are handled from day one.
  • If your systems need new endpoints, we scope that during discovery.
Google Play Submission and Updates

Google Play Submission and Updates

  • We prepare store assets, metadata and compliance checks before submission, then handle updates so new releases go live without disruption.
Building for Android and iOS Together

Building for Android and iOS Together

  • A single cross-platform codebase typically delivers both apps faster than two native builds.
  • Trade-offs exist for hardware-heavy features; we'll advise during discovery.

Built in the UK, not outsourced

We run face-to-face discovery workshops in Belfast and London, then deliver phased builds so you test working software at every milestone. Our team tests across real UK devices and screen profiles. We're a small, senior crew and we like it that way. The people you meet in discovery are the same engineers and designers writing the code.

We used the same in-house approach to ship Papier's cross-platform app in React Native for both Android and iOS, from a single product team through to app store launch.

  • In-house senior team, no subcontracting
  • In-person workshops in Belfast or London
  • Phased delivery with working builds throughout

Why choose Myth as your Android app development company?

How does an Android app development project work?

We work in phases so you see working software early and sign off each stage.

  1. Discovery Workshop

    In-person or remote sessions define scope, target users and the right technical approach. Nothing gets designed or coded until this is done.

  2. UX Design and Prototyping

    Wireframes and user flows come first. Then we build a clickable prototype you can put in front of real users and stakeholders for honest feedback.

  3. Visual Design for Android

    Full UI designs following Material guidelines, tested across common screen sizes and densities.

  4. Development in Phased Sprints

    Short sprints with working builds you can review regularly. Progress stays visible throughout, and you sign off each milestone before we move on.

  5. QA and Device Testing

    We test across a matrix of real Android devices covering the screen sizes and OS versions your users rely on. Not just emulators.

  6. Google Play Launch and Support

    Store listing, submission, go-live. Then ongoing updates and fixes from the same team that built the app.

Are we the right fit?

We're not the right partner for every project. Here's a quick way to tell.

A great fit

  • You want a reliable UK team you can meet in person
  • You need phased delivery with visible progress at every stage
  • Your app needs to connect to existing systems, APIs or databases
  • You're planning for both Android and iOS, now or later

Not the right fit

  • You're after the lowest price above all else
  • You need a template app with no custom functionality
  • You'd rather skip discovery and start coding immediately
  • You want a solo freelancer, not a multi-discipline product team
  • Your timeline doesn't allow for proper testing

One app, both platforms

Most clients want their app on Android and iOS. A single cross-platform codebase often gets you there faster, with one team and lower ongoing maintenance. We decide the right approach during discovery, not by default.

  • Shared codebase, faster delivery
  • One team builds both platforms
  • Native option when the product demands it
  • Decision shaped by your users, not dogma

FAQ

Android app development FAQs

How much does Android app development cost in the UK?

It depends on scope. The pricing tiers on this page give starting points for an MVP and a full product. Simpler apps sit at the lower end and products with complex integrations cost more. You get a fixed-price proposal after a discovery session so you can budget with confidence.

How long does it take to build an Android app?

A focused MVP typically takes eight to twelve weeks. A full product with integrations, accounts and offline support usually runs three to six months. We deliver in phases with working builds at every milestone, so you test progress rather than wait for it.

Should we build native Android or cross-platform?

Most projects suit cross-platform, which gives one codebase for Android and iOS and reaches both stores sooner. We build native Android when the app needs deep hardware access or performance a shared codebase cannot match. We make the call with you during discovery.

Can you build for both Android and iOS at once?

Yes. Most of the apps we build ship on both platforms from one codebase, with one team, so every improvement reaches every user at once. Where a product needs native builds, we design and build both platforms side by side.

How do you handle the range of Android devices and screen sizes?

We design layouts that adapt to screen size and density, test on a set of real devices that reflects your users, and follow platform guidelines so the app behaves as Android users expect. Device coverage is agreed during discovery.

Do you handle Google Play submission and updates?

Yes. We set up the developer account with you, prepare the store listing and policy requirements, manage submission and review, and ship updates after launch. Keeping the app compliant with store requirements is part of ongoing support.

Can the app connect to our existing systems?

Yes. We build the connections between the app and your existing platforms, whether that is a CRM, a booking system, payments or a custom back end. If your systems need new interfaces, we scope that during discovery so there are no surprises later.
