Mobile App Development · Sydney, NSW
Mobile apps that work where your workforce actually works.
Your staff are not at desks. They are in the field, on client sites, at facilities. They need tools that work offline, sync when connected, and handle the complexity of real operational work. Human Nexus builds mobile apps for field workforce, compliance, and scheduling that your team will actually use.

The problems we fix.
Field staff cannot access desktop systems
Care workers, inspectors, technicians, and field sales teams need mobile access to schedules, checklists, client data, and compliance forms. Desktop-only systems create workarounds and double-handling.
Offline capability is an afterthought
Most mobile apps assume always-on connectivity. Real field work happens in areas with poor reception. Our apps work offline and sync when connectivity returns, no data loss, no frustrated staff.
Building separate iOS and Android apps doubles the cost
React Native and Flutter deliver native-quality apps for both platforms from a single codebase. One build, two platforms, half the cost and timeline of native-only development.
How we deliver it.
01
Workflow mapping
We map the field workflow end-to-end: what happens offline, what needs to sync, what compliance evidence must be captured. The app design starts from the field worker's experience, not a wireframe.
02
Prototype on device
Working prototype running on real devices within the first two weeks. Your field staff test it in real conditions and tell us what needs to change.
03
Build and field-test
Full app built with offline storage, sync engine, and backend integration. Tested by your team in the actual field conditions where it will be used.
04
Deploy and train
Published to App Store and Google Play (or enterprise distribution). Staff trained. 30 days of post-launch support included.
What's included.
Field workforce apps
Scheduling, timesheets, client checklists, incident reporting, and task management for care workers, inspectors, and field technicians. Works offline, syncs automatically.
Compliance and audit mobile tools
Evidence capture (photos, signatures, GPS), checklist completion, and compliance reporting built for regulatory environments. Full audit trail from mobile to backend.
Client and patient-facing apps
Self-service portals for clients to view schedules, communicate with providers, upload documents, and track service delivery. Branded to your organisation.
Offline-first architecture
Local SQLite or WatermelonDB storage with background sync. Conflict resolution strategies designed for your specific data model. No data loss in poor connectivity.
Push notifications and alerts
Shift confirmations, compliance deadline reminders, incident alerts. Configurable notification rules integrated with your scheduling and compliance systems.
Enterprise deployment
App Store, Google Play, or enterprise MDM distribution (Intune, Jamf). Managed app configuration, single sign-on, and device policy compliance.
Why Human Nexus.
Built for real field conditions
Our team includes operational consultants who have managed field workforces. We design for low connectivity, battery constraints, and the reality that field staff are not tech support.
Single codebase, both platforms
React Native or Flutter depending on your requirements. One codebase delivers native-quality apps for iOS and Android, cutting development time and cost.
Your team owns the app
Full source code, build pipelines, and App Store credentials handed over. No ongoing licence fees. Your team can maintain and extend the app independently.
Fixed price, clear scope
Scope agreed upfront. Price locked before development starts. No open-ended billing. Change requests priced separately and approved before work begins.
Offline-first by design
Not an afterthought. The data model, sync engine, and conflict resolution are designed for offline operation from day one, tested in real poor-connectivity conditions.
Sydney-based project management
Australian project lead manages delivery. Direct line to the people building your app. No timezone roulette, no communication gaps.
Proof of work
Voice AI scheduling agent operating 24/7 for a disability service provider.
Human Nexus built a mobile-integrated Voice AI system that calls carers, confirms shifts, interprets natural responses, updates the scheduling system, and escalates uncertain cases. The system operates around the clock without coordinator involvement, integrated with the provider's mobile scheduling app used by field staff.
24/7 automated shift confirmation.
Common questions.
React Native or Flutter — which do you recommend?
We recommend based on your requirements. React Native has a larger ecosystem and talent pool. Flutter offers more consistent UI across platforms and stronger performance for animation-heavy apps. Both deliver native-quality iOS and Android apps from a single codebase. We advise during scoping before any commitment.
How much does a mobile app cost?
Simple field tools with basic offline capability start from $25,000 to $50,000. Mid-range apps with sync, backend integration, and compliance features range from $50,000 to $120,000. Large multi-module platforms range from $120,000 to $250,000. Fixed-price quotes after free scoping.
How do you handle offline data and sync?
We design the offline data model based on what field staff genuinely need when disconnected. Local storage (SQLite, WatermelonDB) handles offline operations. Background sync with configurable conflict resolution handles reconnection. We test in actual poor-connectivity conditions.
Can you publish to our existing App Store and Google Play accounts?
Yes. We publish under your developer accounts so you retain full ownership. We handle App Store review, Google Play compliance, and provide all necessary metadata, screenshots, and privacy documentation.
What about app maintenance and OS updates?
30 days post-launch support included. Ongoing maintenance packages cover iOS and Android OS compatibility updates, dependency patches, and minor enhancements. Your team can also take over maintenance because you own the full source code.
Can the mobile app integrate with our existing backend systems?
Yes. We build REST and GraphQL APIs that connect your mobile app to your existing scheduling, CRM, payroll, and compliance systems. If your systems lack modern APIs, we build the integration layer as part of the project.
