Mobile App Development Company in Leeds

Clinical safety or Open Banking conformance is the line where a Leeds app budget steps up: a scoped MVP iOS and Android app at our fixed-fee rates covering UX, design, React Native or native build, a Node.js or Python backend on AWS eu-west-2 (London), UK GDPR documentation, store submission, and a phased rollout, a full production app with payments, third-party integrations, offline sync, and either NHS DTAC and DCB0129 clinical safety or FCA SCA and Open Banking conformance, or a building-society-grade or NHS-trust-grade app with full medical device or banking-app rigour once independent clinical safety review, PRA SS2/21 documentation, MASVS Level 2 penetration testing, and accessibility audits are scoped. We quote fixed fees, which Leeds NHS commissioners and building society finance directors appreciate.

Yes. Our NHS mobile work ships with a Digital Technology Assessment Criteria (DTAC) self-assessment, a DCB0129 manufacturer clinical risk management file (with hazards, mitigations, and a clinical safety case) initiated by a registered Clinical Safety Officer (CSO), a DCB0160 deployment clinical risk management file produced with the deploying NHS trust, and where the app meets the UK MDR 2002 definition of a medical device, an MHRA Class I, IIa, IIb, or III classification and registration. We integrate with NHS login, the Spine, PDS, GP Connect, and the NHS App SDK. Apps ship on the Data Security and Protection Toolkit with appropriate cyber assurance and ISO 27001 evidence. We have patterned engagements after NHS Digital's own published frameworks. Final clinical safety sign-off sits with a CSO on the deploying side.

Yes. Our FCA-regulated banking work for building societies and lenders includes PSD2 Strong Customer Authentication (Article 97 RTS) via biometric, device-binding, and dynamic linking on payment authorisation, FCA Consumer Duty (PS22/9) outcome tracking embedded in analytics so the firm can evidence good outcomes across the four outcomes test, PRA SS2/21 outsourcing register and operational resilience documentation including impact tolerances, FCA SYSC record retention for in-app communications, and OBIE Open Banking conformance for Account Information and Payment Initiation Service connections. We have patterned mobile work after First Direct (HSBC), Yorkshire Building Society, Leeds Building Society, Virgin Money, and Skipton Building Society public app patterns. Apps ship with a Mobile Application Security Verification Standard (MASVS) Level 2 penetration test before App Store and Play Store submission.

Yes. App Store and Play Store submission is part of every Leeds mobile engagement, not a separate change order. We run a pre-submission audit against the most common rejection reasons (App Tracking Transparency consent, payment guideline 3.1.1, health-claim guideline 1.4.1, sign-in alternative requirements, in-app purchase routing), prepare full store metadata localised for English, and where required Welsh, Scots Gaelic, and Irish Gaelic markets, manage TestFlight and Play Internal Testing, and respond to App Review and Google policy queries inside SLA. We do not ship apps that fail submission, and where the brand requires a managed enterprise distribution (NHS internal-only, building society staff-only) we configure Apple Business Manager and Google Managed Play with appropriate MDM (Intune, Jamf, VMware Workspace ONE) before launch.

All builds ship to WCAG 2.2 AA via VoiceOver (iOS) and TalkBack (Android) testing, with dynamic type, high-contrast, and reduced-motion support. For NHS clients we additionally meet the NHS Service Manual accessibility guidance and the Equality Act 2010 reasonable adjustments expectations the Equality and Human Rights Commission applies to private sector apps. We run axe-equivalent automation in CI on every pull request, manual screen-reader testing before each release, and a published accessibility statement on either the NHS template or a private sector equivalent. For Leeds public sector apps under the Public Sector Bodies Accessibility Regulations 2018, the same accessibility monitoring that applies to web sites applies to mobile apps, and we produce the evidence pack the Cabinet Office and the Government Digital Service expect.

A typical Leeds building society savings or current-account app (Yorkshire Building Society-tier, Leeds Building Society-tier, Skipton Building Society-tier) takes twenty to thirty-two weeks from kickoff to launch, assuming back-office API readiness on the building society side. Week 1 to 4 is discovery, FCA Consumer Duty outcome mapping, PRA SS2/21 third-party risk register entry, and design system kickoff. Week 5 to 16 is build on React Native or native Swift and Kotlin with full PSD2 SCA. Week 17 to 22 is MASVS Level 2 penetration testing, FCA Consumer Duty journey verification, accessibility audit, and TestFlight and Play Internal beta with members. Week 23 to 26 is store submission, phased rollout, and operational resilience handover. NHS DTAC and DCB0129 apps run a similar timeline, with clinical safety review on the critical path.

Yes. Our NHS mobile integrations include NHS login (NHS England's federated identity) for citizen-facing authentication, the Spine and Personal Demographics Service (PDS) for patient demographics, GP Connect for GP record access where appropriate, e-Referral Service (e-RS) where the journey is referral-driven, NHS App SDK partner integration for surfacing the journey inside the NHS App rather than a separate brand, and the National Record Locator. We work alongside an NHS Digital onboarding team during the technical assurance phase and we produce the DSP Toolkit, ISO 27001, Cyber Essentials Plus, and MHRA evidence the assurance team needs. We have patterned engagements after NHS Digital's published integration guides. Final live integration sits behind NHS England's onboarding queue, which we plan for at discovery.

Yes. Since Channel 4 relocated its national HQ from London to the Majestic on City Square in 2019, Leeds has become a meaningful UK broadcast and OTT mobile hub. Our broadcast work includes iOS, Android, tvOS, Android TV, and Fire TV apps for streaming, video-on-demand, and live linear, with HLS and DASH manipulation, DRM via FairPlay (Apple), Widevine (Google), and PlayReady (Microsoft), CDN integration with Akamai, Fastly, or Cloudflare Stream, and advertising integration with SSAI (server-side ad insertion) via Yospace or Mediatailor. Ofcom Video on Demand obligations under the Communications Act 2003 and the Audiovisual Media Services Regulations 2020 (including age-rating and access services) ship inside the build. We have patterned work after the All 4 (Channel 4) app's public architecture without claiming we built it.
