What does FictiveBox's web and mobile engineering service include?

Modern web applications, native mobile for iOS and Android, offline-first synchronisation, design systems, accessibility engineering to WCAG 2.2 AA, and performance work against explicit budgets.

What makes an industrial or field app different from a normal app?

The operating conditions. Networks drop, devices are shared between shifts rather than owned by one person, and screens are used with gloves and in poor light. That drives offline-first sync with real conflict resolution, shared-device session patterns, and performance budgets tested on slow connections rather than office wifi.

When should a company invest in a design system?

When the same patterns are being rebuilt inconsistently across several products or platforms, and when accessibility and cross-platform parity keep regressing. A design system turns those into a single place to fix rather than a recurring cost in every release.

Is accessibility included or an add-on?

It is engineered in from the start rather than remediated at audit time. Work targets WCAG 2.2 AA, and accessibility is treated as part of the definition of done rather than a later conformance exercise.

Which web and mobile technologies are used?

React, Next.js, TanStack, TypeScript, Swift, Kotlin, React Native, Tailwind, Storybook and Playwright. You own the source code, the infrastructure definitions, the runbooks and the documentation. There is no black box and no lock-in, and we hand over cleanly whenever you ask.

Web & Mobile Engineering

Web and mobile apps built for the field, not just the showroom.

We engineer web and native mobile applications for the places where networks drop, devices are shared between shifts and screens get dirty. Offline-first sync, accessibility, performance budgets and design systems engineered to survive depots, warehouses and remote sites.

Capabilities

What we deliver

Modern web

React, Next.js, TanStack Start, Remix and Vite with strict TypeScript, Core Web Vitals budgets enforced in CI.

Native mobile

iOS in Swift and SwiftUI, Android in Kotlin and Compose, React Native where the cross-platform tradeoff actually makes sense.

Offline-first sync

CRDTs, conflict resolution and resilient queues for unreliable industrial networks. Users never lose work because wifi dropped.

Design systems

Token-driven systems, Storybook, Figma integration and brand-grade theming that survives rebrands and acquisitions.

Accessibility

WCAG 2.2 AA conformance audited and signed off, including assistive-tech testing. Not a checkbox.

Performance

Bundle, runtime and network budgets enforced in CI. Sub-second TTI on 3G for field apps is the target, not the dream.
