App Development for Regulated Businesses

Apps your business will love

We design and build native and cross-platform applications for iOS, Android, macOS, Windows and Linux — engineered under ISO 27001 and ISO 42001 controls, with the evidence pack to prove it.

Every platform your business runs on

Whether your users are on a phone, a workstation, or a Linux server in a back office, we build apps that feel native and behave predictably under audit.

iOS

Swift, SwiftUI, UIKit

Native iPhone and iPad apps designed for App Store distribution, MDM rollouts, and tightly-controlled enterprise estates.

Android

Kotlin, Jetpack Compose

Modern Android apps built for Google Play, managed work profiles, and rugged device fleets used across regulated operations.

macOS

Swift, AppKit, SwiftUI

First-class desktop experiences for Mac, signed and notarised, ready for Jamf, Kandji and other enterprise distribution tools.

Windows

.NET, WinUI, WPF

Performance-focused Windows applications signed with EV certificates and packaged for MSIX, Intune and Group Policy delivery.

Linux

Qt, GTK, Electron

Robust Linux clients and daemons for engineering, lab, and back-office environments where uptime and auditability matter most.

One codebase, many platforms?

Where it makes sense, we ship with Flutter, React Native or .NET MAUI to reach every platform from a shared codebase — without compromising on the security and audit trail your business depends on.

Built for ISO 27001 and ISO 42001

Engineering under audit-grade controls

We don't bolt on compliance at the end. Our delivery process is shaped around the controls you already report against, so every release is audit-ready by default.

Documented requirements

Every feature traces back to a versioned requirement, signed off by you, with a clear change history for auditors.

Risk-driven design

Threat modelling and DPIAs run alongside design, so security and privacy controls are baked in, not bolted on later.

Secure-by-default code

Encryption in transit and at rest, secret management, hardened auth, role-based access, and full audit logging as standard.

Controlled change management

Branch protections, peer review, signed commits, and traceable releases keep your codebase audit-ready at all times.

Formal testing

Unit, integration, end-to-end, accessibility, and penetration testing with documented evidence stored in your evidence pack.

Evidence on demand

Policies, logs, test results and approvals export cleanly for ISO 27001, ISO 42001 and GDPR audits with no last-minute scramble.

Compliance ready out of the box

Encryption at rest and in transit, role-based access control, audit logging, SSO, and exportable evidence packs are part of every project, not premium extras.

  • AES-256 encryption at rest
  • TLS 1.3 in transit
  • Role-based access control
  • Tamper-evident audit logs
  • SSO and MFA support
  • GDPR-aligned data handling

How we work with you

A predictable, six-step delivery process designed around regulated environments, with clear milestones and documented sign-offs.

01

Discovery

We map the user journey, regulatory scope, integrations and success metrics in a structured discovery sprint.

02

Design

Wireframes, prototypes and design systems shaped around your brand, accessibility targets, and platform conventions.

03

Develop

Iterative builds delivered in two-week cycles, with demos, working software, and traceable progress every step of the way.

04

Test

Automated and manual QA, security testing, accessibility checks, and a documented test evidence pack signed off by you.

05

Deploy

Store submissions, MDM packaging, code-signed installers and rollout plans tailored to your distribution model.

06

Support

Ongoing maintenance, monitoring, OS upgrade tracking, and SLA-backed support so the app stays healthy in production.
