Mobile Application
Mobile apps built for your customers, team and operations.
Well-designed mobile applications that put your service in your users' pockets — reliably and securely.
Under the hood
A real-time view of how this is engineered, run and kept honest in production.
Implementation stack
Flutter or React Native for cross-platform delivery
Encrypted on-device database for offline capabilities
REST/GraphQL backend APIs with typed contracts
Push notification microservice (APNs / FCM) with delivery tracking
Biometric authentication via secure enclave / keystore
App observability for crashes, performance and usage
Remote configuration for staged feature rollouts
Live handling loop
Authenticate
Biometric or session-backed sign-in unlocks the local vault.
Sync
Local data reconciles with the backend on connectivity change.
Render
The app works from the local store first, then refreshes.
Act
User actions validate against backend state before committing.
Notify
The push microservice delivers targeted, batched notifications.
Measure
Crash and performance telemetry guides the next release.
Production integrity
On-device data encrypted at rest; keys live in the secure enclave.
Session pinning and token rotation for account safety.
Push fallback and expiry so notifications never duplicate.
App attestation and jailbreak/root detection where policy demands it.
Real-world use
A representative deployment of this service in practice.
Who it was built for
A field-service crew completing checklists in tunnels and rural zones (anonymised).
The problem
Technicians lost work every time a checklist hit a dead zone; managers only knew a job was done hours later, and safety callouts could not reach crew members by role.
The deployment
CoveScreen built a cross-platform app with an encrypted offline database, role-targeted push notifications, and biometric sign-in for quick, secure shift starts.
The mechanism
Checklists write to the encrypted local store and sync when connectivity returns; the push microservice targets crew by role and region with delivery tracking; biometric auth unlocks the local session without sending credentials on every open.
Operational insight
Benchmark targets this is engineered to hold. Stats are framed as targets and SLAs — not fabricated outcomes.
- Offline
- Full survey/checklist functionality without signal
- < 1 s
- Cold-start target on mid-range devices
- 100%
- Biometric-backed sign-in on supported devices
