High-performance reactive mobile apps with offline capability.

Enterprise mobile apps fail when field users lose connectivity or when barcodes take too long to scan. We build reactive, native-packaged OutSystems apps with deep offline databases and device integration.

What it is

Custom Mobile Applications

OutSystems Mobile Applications provide native iOS and Android packages using Cordova/Capacitor frameworks. We build custom field-service applications, barcode/RFID scanners, driver dispatch clients, and customer-facing service portals. These apps run fast, store data locally when offline, and synchronize seamlessly when a network connection is restored.

When we recommend it

Fit signals.

  • Your field workers operate in warehouses, basements, or areas with poor cell service
  • You need native capabilities like camera scans, GPS tracking, and bluetooth printing
  • You need to deploy a custom app to both App Stores in under 12 weeks
Capabilities

What we deliver in Custom Mobile.

Every capability below is practiced across multiple production engagements — not a scoping checklist.

Mobile features

  • Local storage & SQLite offline database sync
  • Native device integrations (camera, barcode, GPS, push notifications)
  • Biometric authentication (FaceID, fingerprint)

Deployment & packaging

  • One-click Android/iOS native package generation
  • Mobile app updates bypass App Store reviews (over-the-air updates)
  • Mobile-optimized responsive CSS grids
Engagement patterns

The shapes this work
usually takes.

Field service mobile pod

An 8-week build to deliver an offline-capable inspection app for field technicians, complete with photo upload and PDF receipt signing.

What goes wrong

Pitfalls we've seen
and how we avoid them.

Over-synchronizing offline data

Attempting to sync the entire enterprise database to a mobile device will crash the app. We design strict delta-sync payloads.

FAQ

Common questions about Custom Mobile.

No. OutSystems compiles to a single reactive codebase that deploys onto both platforms, drastically reducing maintenance costs.
