Mobile App Development Company in the UK
A London-founded team designing and engineering native and cross-platform iOS and Android apps for UK businesses — built to UK data-protection standards, from first sprint through App Store launch.
Real products we've built
Quick answer: Apptechies is a London-founded mobile app development company building native iOS, native Android and cross-platform apps for UK businesses, with GDPR and Data Protection Act 2018 practices built into the architecture from day one — not a compliance checklist applied before launch.
What a UK Mobile App Development Company Should Actually Deliver
UK Compliance by Design
GDPR and Data Protection Act 2018 considerations built into the data architecture from the first sprint, not retrofitted before launch.
Elastic, Cloud-Native Scaling
Architectures built on AWS, Azure or GCP that hold up under real UK peak-hours traffic, not just a load-test benchmark.
AI Woven Into the Product
On-device inference, recommendation engines and generative features built into the app experience, not bolted on as a chatbot widget.
Clean Systems Integration
CRM, ERP, payment gateways and legacy UK banking or NHS APIs connected without brittle middleware hacks.
A Mobile Partner That Understands UK Compliance, Not Just UK Time Zones
Plenty of agencies will build you an app. Fewer understand what changes when your users, your data, and your regulator are all in the UK. Founded in London in 2018, we've spent 8+ building products where GDPR, the Data Protection Act 2018, and sector rules like FCA or NHS DTAC guidance aren't an afterthought — they're part of the architecture conversation on day one.
That approach has shipped 600+ solutions across 25+ industries, with a 99% client satisfaction rate — and it's why UK businesses come back for their second and third app rather than shopping around.

Your UK Business Deserves More Than an Off-the-Shelf App Template
Generic app builders can't handle regulated UK data, complex workflows, or the integrations your business actually runs on.

Data Protection Isn't a Feature We Add Later
UK GDPR & Data Protection Act 2018
Data minimisation, lawful-basis mapping and encryption-at-rest are architectural decisions we make before writing a single screen, not a pre-launch checklist item.
App Store & Play Store Guidelines
Every release is built against current Apple and Google review guidelines, so submissions don’t stall on avoidable compliance rejections.
Sector-Specific Regulation
FCA-aware architecture for FinTech clients, NHS Digital Technology Assessment Criteria awareness for healthcare apps — we scope regulatory constraints during discovery, not after a rejected audit.
Why UK Businesses Rely on Apptechies
Senior Engineers, Not Hand-offs
The engineers who scope your architecture are the ones who build and support it — no rotating cast of junior developers learning on your budget.
A London-Founded Team
Founded in 2018 and headquartered in London, with 150+ specialists working across 30+ countries — UK time-zone overlap is the default, not an accommodation.
Recognised Delivery Quality
Rated a Top Web & App Development Company in the UK by Clutch in 2025 — based on verified client reviews, not a self-issued badge.
The Mobile Stack We Build In
Overcoming Common UK Mobile App Challenges
Our last agency disappeared after launch — who maintains the app now?
Every engagement includes a post-launch support window, and most UK clients continue with an ongoing maintenance retainer with the same engineers who built the app, not a support queue.
We need to integrate with an ageing internal UK enterprise system.
We regularly bridge mobile apps into legacy ERPs, on-premise databases and internal APIs that were never designed for mobile — scoped properly during discovery, not discovered mid-build.
Our app idea touches sensitive UK customer data.
We’re glad to sign an NDA before any detailed discussion, and data-protection architecture is scoped as part of the very first sprint, not an afterthought.
We’re not sure if we need native or cross-platform.
We’ll tell you honestly. Native suits performance-critical or camera/AR-heavy apps; cross-platform suits content and workflow apps where one codebase and faster iteration matter more.
Flexible Ways to Work With Our UK Mobile Team
Dedicated Team
A UK-timezone-overlapping engineering team, 100% dedicated to your app, reporting directly to you.
Extended Team
Embedded inside your existing team, matching your tools, standups and sprint cadence.
Project-Based
Fixed scope, timeline and budget — ideal for a well-defined app build with a clear deadline.
Everything You Need to Know Before You Hire.
The questions we hear most from teams hiring a mobile app development team. Don't see yours? Ask us directly on the right.
A focused MVP typically runs $30,000–$70,000, while a full-featured enterprise app with AI features and complex integrations can run $150,000+. The real driver is scope, which is why we quote against your actual requirements after a discovery call rather than a generic range.
Yes — data minimisation, lawful-basis mapping and encryption-at-rest are architectural decisions made during the first sprint, not a pre-launch audit item. For FinTech and healthcare clients we also scope FCA or NHS-relevant considerations during discovery.
An MVP typically takes 10–14 weeks from kickoff to App Store submission. A more complex enterprise app with multiple integrations and AI features usually runs 20–28 weeks.
Yes. We regularly take over ageing apps — migrating outdated frameworks, re-architecting for performance and modernising UI/UX — usually without a ground-up rewrite that would put your roadmap on hold.
Every engagement includes a post-launch support window, and most clients continue with an ongoing maintenance and iteration retainer with the same engineers who built the app.
FinTech, healthcare, logistics, on-demand delivery and real estate are where we see the most UK demand, though our 600+ delivered solutions span 25+ industries in total.
Yes — we’re happy to sign an NDA before any detailed discussion of your app concept or business logic. Just mention it when you reach out.
