Mobile success is decided by context: connection quality, interruptions, battery and one-handed use. We plan and build mobile applications — native or cross-platform with React Native or Flutter — around those realities, connected to dependable backend services. ## Fit For businesses extending a service to mobile, replacing a paper field process, or shipping a customer app that must work beyond perfect connectivity. ## Scope - **Product & platform choice:** An honest evaluation of native, React Native, Flutter and web-app approaches against your budget, update cadence and the device features you truly need. - **App design & build:** Touch-first interfaces with offline behaviour, sensible sync, notifications and states designed for interruptions — not a desktop screen squeezed onto a phone. - **Backend & sync services:** APIs, authentication and data synchronisation designed for flaky connections and conflicting edits, so records stay trustworthy. - **Release & store operations:** Signing, store listings, staged rollouts, crash reporting and an update path your team can actually operate. ## Process 1. **Choose the platform honestly:** Agree the approach — native, cross-platform or web — from device needs, budget and maintenance capacity. 2. **Design for interruption:** Prototype the core loop on real devices, including offline use, before building the full feature set. 3. **Ship and operate:** Release through the stores with crash reporting and staged rollouts; agree who triages what comes back. ## Examples ### A field operations app - Challenge: Field staff fill paper forms in basements and remote sites, then re-enter data at the office. - Approach: Build an offline-first app that captures records locally, syncs when connectivity returns and flags conflicts for review. - Deliverable: An offline-capable app with sync, plus a web console for the office team. ### A customer companion app - Challenge: Customers manage their accounts on a phone, but the mobile web experience is painful. - Approach: Scope the highest-value tasks — status, bookings, documents — and ship a focused app with notifications instead of porting every desktop feature. - Deliverable: A store-ready app for the priority journeys, with a measured case for what comes next. ### A cross-platform rebuild - Challenge: Separate iOS and Android codebases double every change and drift apart. - Approach: Consolidate onto a React Native or Flutter codebase where device needs allow, keeping native work only where a feature demands it. - Deliverable: A single-source app with platform-specific edges documented and tested. ## FAQ ### Native or cross-platform? It depends on device features, budget and how often you will ship. Cross-platform with React Native or Flutter covers most business apps well; deep hardware integration can justify native work. The trade-offs are agreed in scoping, not assumed. ### Do you publish to the app stores for us? We prepare builds, listings and release notes and take them through review. The developer accounts remain yours — the app and its store presence belong to you. ### Will the app work offline? Where the workflow needs it, yes — offline capture with later sync is a design decision made early, because it shapes the data model. We will tell you plainly when offline support complicates a feature. ## Reference architecture A reference mobile structure. The device context — connectivity, interruptions, battery — shapes the app, its sync and its release path. ### App Offline state → Touch journeys Keep the core tasks usable without connectivity, with screens designed for one-handed, interrupted use. Review: Test airplane-mode flows, resume after interruption, permission prompts and the smallest supported screen. ### Sync Queued changes → Conflict rules Move records between device and backend with rules for conflicting edits and failed uploads. Review: Test duplicate submissions, conflicting edits from two devices and behaviour when sync fails repeatedly. ### Release Store operations → Crash & usage signals Ship updates through the stores with staged rollouts and the signals to catch regressions quickly. Review: Agree signing ownership, review timelines, rollback options and who triages crash reports. Illustrative planning model; scope and deliverables are agreed per project. ## Technology choices The device context decides the architecture ### App React Native · Flutter · Native where a feature demands it Choose the approach per feature: shared code where it is honest, native work where a device capability demands it. ### Sync Local store · Queued mutations · Conflict rules Design offline capture and reconciliation around the workflow's tolerance for delayed updates. ### Delivery Store pipelines · Crash reporting · Staged rollout Agree signing, release notes, rollout stages and monitoring before the first submission. ## Quality checks before handover ### Offline journeys Complete the core tasks in airplane mode and after interruption; verify queued records sync without duplication. ### Device realities Check the smallest supported screens, system font scaling, permission prompts and battery-sensitive behaviour. ### Release readiness Verify store listing assets, review compliance, crash reporting and the rollback plan for the first release. ## Preparing for a project Bring the tasks users must complete on the move, target devices, connectivity realities and any existing backend the app should connect to.
