What we do

We build the software big companies won't — for the people who need it most.

Social-responsibility software: we pick up the problems big companies skip because there isn't enough money in them, and engineer them properly — apps and the web platforms behind them, with privacy, accessibility and (where it matters) medical language done right. iOS specialists at heart, never limited to it. Based in the UK, working with organisations and founders who care about craft.

Core services

End-to-end product development

We handle the full journey — from concept to the App Store and the open web — with the depth of a specialist and the rigour safety-critical software demands.

✦ Product Strategy & UX Design

We turn complex health workflows into interfaces that feel calm and obvious. User research, interaction design, prototyping, and the ruthless simplification required when you're asking users to trust you with sensitive data.

  • User research & persona development
  • Information architecture & flow design
  • High-fidelity prototyping in Figma
  • Accessibility-first design (WCAG 2.2 AA)
  • Design systems & component libraries
Outcome A validated product vision and pixel-perfect designs ready for engineering, with clarity on what to build and why.

⌘ Native iOS & watchOS Engineering

Swift, SwiftUI, and the latest Apple platform APIs. We build using clean architecture principles (DDD, SOLID), comprehensive automated testing, and the kind of reliability that health users deserve. Performance, battery efficiency, and Liquid Glass material support on the latest devices.

  • Swift & SwiftUI (iOS 16+, watchOS 10+)
  • Clean Architecture & Domain-Driven Design
  • Comprehensive unit, snapshot & UI testing
  • HealthKit, Core Data, local-first persistence
  • Apple Watch companion apps & complications
  • Push notifications & background processing
Outcome A robust, maintainable codebase that can evolve with your product — built to last, not to rewrite.

▲ Native Android Engineering

Kotlin and Jetpack Compose on current Android SDKs — the same clean architecture, the same testing discipline, the same safety-critical bar as our Apple work. Built for real devices, not just flagships.

  • Kotlin, coroutines & Flow, Jetpack Compose
  • Material Design 3, adaptive layouts for phones, tablets & foldables
  • Room, WorkManager, DataStore — local-first persistence
  • Device-matrix testing across API levels & OEM skins
  • Google Play launch: Console, data-safety, staged rollouts
  • Battery discipline: Doze & background-execution limits respected
Outcome An Android app your users can't tell apart in quality from our iOS work — because it's held to the same gates.

🏢 Corporate & Bespoke Applications

Custom-built iOS applications for organisations. Whether you need an employee wellbeing app, a patient-facing tool, or an internal workflow application, we build to your specification with enterprise-grade quality.

  • Build-to-spec for enterprise & healthcare organisations
  • Employee wellbeing & health tracking apps
  • Patient-facing clinical tools
  • Integration with existing systems & APIs
  • MDM support & enterprise deployment
Outcome A polished, branded application that integrates with your organisation's needs and meets Apple's exacting standards.

🎨 White-Label Apps

White-label apps custom-engineered on proven foundations (like HRTMe), tailored to your users — not a template with your logo on it. For example: a menopause and HRT wellbeing app for an employer, built on HRTMe's clinical accuracy and user flows, with your brand, feature set, and compliance requirements baked in from day one.

  • Custom branding & design system application
  • Feature configuration & workflow tailoring
  • Data export & reporting capabilities
  • Compliance requirements integration
  • Ongoing maintenance & feature evolution
Outcome A fully-branded health app with proven foundations and custom engineering, deployed faster than building from scratch.

🩺 Health App Consulting

Medical accuracy matters. We work to ensure our health apps use language that's both medically accurate, corroborated by NHS practitioners, and accessible to patients.

  • Medical terminology & language review
  • Extensive workflow validation
  • Medication regimen modelling
  • Patient education content review
Outcome Confidence that your app speaks accurately to both medical professionals and patients, reducing risk and increasing trust.

🛡 Privacy, Security & Accessibility Engineering

We architect apps with on-device storage, no accounts, and zero health data in analytics — privacy as the foundation we build on. For clients, that means defensible B2B positioning: you can tell your users their data never leaves their device, and we give you the engineering to back that claim. Plus WCAG 2.2 AA compliance, VoiceOver optimisation, and Dynamic Type support throughout.

  • Local-first, on-device data architecture
  • Privacy-preserving analytics (TelemetryDeck)
  • WCAG 2.2 AA accessibility compliance
  • VoiceOver & Dynamic Type support
  • Secure data export & backup flows
Outcome An app that every user can access and trust — including those who need assistive technologies or have the highest privacy expectations.

🚀 App Store Launch & Growth

Getting approved is one thing. Being discovered is another. We handle App Store submission, optimise your listing for organic discovery, and build SEO-driven marketing sites that rank. All growth strategies are organic — we don't do paid ads.

  • App Store Connect submission & review management
  • App Store Optimisation (ASO) — metadata, keywords, screenshots
  • Marketing website design & build (SEO-first)
  • Organic growth strategy & content planning
  • App analytics & performance monitoring
Outcome A live app that users can find, with a marketing presence designed to convert and a roadmap for sustainable growth.

Working with us

Why onshore, and how we work

UK-based means shared time zones, shared regulations, and direct communication with the person building your product.

  • 01

    Same time zone, same regulations

    No overnight handoffs. No legal ambiguity. UK GDPR compliance, straightforward contracts, and real-time communication during your working hours.

  • 02

    You work with the builder

    No account managers. No offshore teams. You work directly with Jane — the principal engineer who architects, codes, tests, and ships. Faster decisions, deeper understanding, zero lost context.

  • 03

    Health domain expertise

    We've built HRTMe from lived experience and real clinical input. We understand medication regimens, cyclical schedules, anxious users, and the gap between medical terminology and patient understanding.

  • 04

    Long-term thinking

    We build for maintainability. Clean architecture, comprehensive tests, documented decisions. Your codebase won't be a mystery in six months — it'll be an asset you can evolve.

Engagement models

We work in two ways, depending on the scale and certainty of your project:

Fixed-scope projects

Best for well-defined briefs. A clear deliverable, a fixed price, a defined timeline. We scope it properly upfront, then deliver the whole thing.

Retained partnership

Best for ongoing product development. A monthly retainer for continuous iteration, feature development, and strategic input as your product evolves.

Not sure which fits? Start with a paid discovery phase — we'll validate the idea, scope the work, and recommend the right engagement model from there.
