What we offer

React Native
engineering services.

React Native engineers who write native modules when it matters and Hermes-friendly JS when it doesn't. Live builds, EAS pipelines, app store submissions handled.

01 — Apps

Cross-platform apps

iOS + Android from one codebase — Reanimated, gesture handler, Hermes, the actually-modern RN stack.

02 — Native modules

Native modules

Swift / Kotlin / Objective-C / Java bridges when the JS layer isn't enough — written and maintained by the same team.

03 — EAS

EAS & CI/CD

Expo EAS, GitHub Actions, Fastlane — build, sign, submit. App Store / Play Store reviews handled.

04 — State

State & data

TanStack Query, Zustand, RTK, Redux — pattern-fluent, opinionated, profile-tested at scale.

05 — Performance

Performance & profiling

Hermes profiling, JS thread vs UI thread, image & list virtualisation — apps that don't drop frames.

06 — Maintain

Maintenance & upgrade

RN version upgrades (the gnarly ones), dependency hygiene, OS-update reactive patches.

Client reviews

What clients
say.

Pulled from independently-verified Clutch reviews — 60+ of them, 4.9 average.

Native modules where it matters, RN-JS where it doesn't — they actually knew the difference.

EAS pipelines, Fastlane, signing — they handled the publishing tax so we could focus on product.

RN upgrade from 0.66 to 0.74 in a single sprint. Most teams stretch that across a quarter.

Frequently asked

The honest
questions.

Why choose Magora as your London software development company?

Magora is a London-based software development company that provides mobile, web and AI product development, and helps businesses ship bespoke solutions backed by 15 years of delivery.

Our senior Product Owners and Project Managers dive into your business goals during Discovery to create a product vision that gives end users a seamless experience.

Top-notch mobile, web and AI developers plus QA engineers deliver high-quality code at any complexity, and our UI/UX design team ensures the experience meets the strictest guidelines.

How long does it take to develop a custom app?

A coded prototype lands in 5–10 working days. An MVP ships in 6–8 weeks. A full production mobile or web project runs 3–6 months. Software is a long-term partnership — post-release maintenance and new updates keep the product competitive.

What tools do you use for mobile & web app development?

We use the most well-known frameworks to ship software with great usability: React.js, Node.js, Kotlin, Swift, Angular, Flutter and React Native. AI work uses OpenAI, Anthropic and Google Gemini APIs alongside open-source models (Llama, Mistral, Qwen) on AWS and GCP.

What does it cost to hire Magora as your software development company?

Typical day rates in London run £30–£90 per hour. Our 2026 paid pricing (GBP):

  • Free working prototype + written analysis from a senior Product Owner before any paid engagement — no commitment, no charge.
  • Product Discovery: from £3,000.
  • Startup MVP: from £10,000.
  • Full production mobile or web project: from £30,000.
  • AI development, bespoke enterprise software and CRM platforms: scoped after Discovery.

We transfer full ownership of source code, designs and IP to the client on payment.

Does Magora offer AI and machine-learning development?

Yes. Magora has a dedicated AI & ML practice delivering LLM-powered applications, retrieval-augmented generation (RAG) pipelines, AI agents, deep learning models, fine-tuned open-source models, and integrations with OpenAI, Anthropic and Google Gemini APIs. See also our take on generative AI and Apple Intelligence on iOS.

Engagements range from short proofs of concept to multi-month production builds. All work is discovery-led, GDPR-compliant, with full ownership of code and data delivered to the client.

Where is Magora Systems based?

Magora Systems is headquartered in London, United Kingdom, at Office 4.01, 4th Floor, The Tea Building, 56 Shoreditch High Street, London E1 6JJ.

Legal entity is Thinking Fish Ltd (UK Companies House 03637036), founded in 2010. We also operate a US presence at 17001 Collins Ave, Sunny Isles Beach, FL 33160.

Finance (FinTech), healthcare and pharma, hospitality and tourism, real estate, transport and logistics, e-commerce and retail, education, automotive, construction and IT/telecom.

Past clients include AstraZeneca, Grant Thornton, Toyota, Unilever and Cisco. See full case studies.

Does Magora handle GDPR and data-protection compliance?

Yes. As a UK-based developer, Magora delivers GDPR-compliant systems by default: data-minimisation review during discovery, consent flows, data-subject-access tooling, encrypted-at-rest storage, audit logging, and EU/UK data-residency options on AWS and GCP.

For AI projects Magora also runs an EU AI Act readiness review before deployment.

Will you support the app after launch?

Yes — to stay among cutting-edge technologies and keep up with changing demand, the product needs constant maintenance. During the maintenance period we analyse all incoming inquiries, evaluate severity and: fix defects, form a Product Backlog from low-medium defects and user feedback, plan and propose enhancements that add value, update libraries and tweak based on API changes to maintain stability, and monitor the code stage for critical security updates. Same team also handles legacy software modernisation if your stack needs lifting.

Who owns the intellectual property?

IPR in bespoke software shall, without prejudice to our rights in pre-existing IPR, be transferred to you on payment of the requested amount relating to such work. Where you have provided us with third-party materials, it is solely your responsibility to ensure those materials may be used as directed without infringing any IPR, laws or regulations.
