Mobile App Development

We build mobile apps for field service, healthcare, regulated workflows, and productive B2B usage. Not just app UI, but the mobile operating layer: offline data, backend integration, device features, store release, and lifecycle maintenance for iOS and Android.

Build

When this service makes commercial sense

This service fits when mobile usage is a critical part of the business process: field service, patient companion apps, offline appointments, hardware access, or sensitive data capture. The critical question is not only the app interface, but whether data model, offline behaviour, device features, store requirements, and operations work together cleanly. We recommend cross-platform or native implementation based on device access, offline complexity, performance needs, app-store lifecycle, team handover, and long-term maintenance.

Project output

What you own after the project

You receive a production-ready mobile codebase and the technical foundation to make distribution, operations, and future development decisions deliberately. Options such as store release, backend sync, or monitoring are explicitly defined in scope.

iOS and Android codebase with documented architecture
Build and testing process with documented signing and distribution strategy
Offline and error-handling concepts; sync concept only when data synchronisation or central administration is needed
Technical handover with lifecycle notes for OS/SDK updates, store-policy changes, or later modules
Ionic/Capacitor, React Native, or native modules depending on platform requirements
Local storage, offline queues, sync rules, and conflict handling
Optional integration with .NET, Node.js, Firebase, Azure, AWS, or existing API backends when the app needs sync, user accounts, reporting, or central administration
Platform-specific build configuration for iOS and Android, including permissions, privacy metadata, test-build workflow, and release documentation
Crash reporting, monitoring, and analytics are selected and documented based on operating model and privacy requirements
Cost drivers

Pricing follows mobile risk, not screen count

Effort comes from platform depth, data behaviour, and operating requirements. A simple online form app is a different scope from an offline-capable regulated app with device integration and store responsibility.

Offline sync, local encryption, and conflict handling

Native features such as camera, files, biometrics, push, or sensors

Backend, database, ERP, or API integration

Apple App Store / Google Play release, test devices, privacy disclosures, and maintenance

Mobile App Development

Specific delivery depth

We build mobile apps for field service, healthcare, regulated workflows, and productive B2B usage. Not just app UI, but the mobile operating layer: offline data, backend integration, device features, store release, and lifecycle maintenance for iOS and Android.

Platform

Cross-platform with controlled native bridges

Ionic, Capacitor, or React Native are used where they improve maintainability and delivery speed.

  • iOS and Android build pipelines
  • Biometrics, camera, files, and push
  • Clear app-store release handover
Offline

Mobile data without assuming connectivity

For field-service and healthcare contexts, we plan local storage, synchronisation, and conflict rules explicitly.

  • Offline sync and retry strategies
  • Encrypted local data storage
  • PDF protocols and structured exports
Lifecycle

Apps that survive platform updates

Mobile apps age faster than web systems: iOS and Android versions, store rules, SDKs, and plugins change continuously. We plan this lifecycle from the start.

  • Dependency and plugin audit
  • OS, SDK, and app-store policy updates
  • Crash, performance, and release monitoring
Data Integration

Mobile app on top of existing data

Mobile apps can connect to existing backend APIs, SQL databases, ERP systems, or specialist business systems without replacing the desktop process immediately.

  • API layer in front of existing databases
  • Offline cache with sync rules
  • Conflict handling for mobile changes
Mobile UX

Fast, resilient use in real conditions

A productive app must remain usable with weak connectivity, long forms, mobile interruptions, and different device classes.

  • Fast startup and responsive interfaces
  • Network, battery, and storage awareness
  • Accessible forms and low-friction data entry
Native Features

Device capabilities by workflow

When the workflow requires it, we integrate native capabilities deliberately. Every feature is evaluated against platform permissions, privacy, battery usage, and maintainability.

  • GPS, maps, camera, files, PDF export, and biometric access
  • Local reminders, push notifications, widgets, and watch extensions
  • QR/barcode scanning, sensors, Bluetooth, or background sync when needed
Example scenarios

What these platforms can look like in practice

Not generic use cases, but typical technical situations where a custom enterprise platform becomes commercially justified.

Field-service app with offline protocols

Situation
Technicians work on site with weak connectivity, capture tasks, photos, checklists, and signatures, then need clean PDF protocols or back-office data later.
Implementation
A cross-platform app with offline storage, sync queue, media handling, PDF generation, authentication, and API integration into existing scheduling or ERP systems.
Outcome
On-site work remains possible without stable connectivity. The back office receives structured data instead of photos, emails, and delayed manual transfer.

Patient companion app for sensitive documentation

Situation
Patients or medical users regularly document symptoms, medication, or progress data. Privacy, low friction, and reliable local usage are critical.
Implementation
A mobile app with encrypted local storage, biometric access, reminder logic, optional backend sync, and exportable reports.
Outcome
Documentation becomes easier in daily use while staying technically controlled: sensitive data, clear permissions, and traceable export paths.

Mobile extension for existing enterprise software

Situation
A company already has a working backend or database, but specific roles need mobile access to status, tasks, approvals, or data capture.
Implementation
A mobile app as a focused extension: API layer in front of existing systems, role-based mobile UI, push notifications, and clearly bounded write paths.
Outcome
The existing system remains authoritative, while mobile users can complete critical actions faster and in a more structured way.
