Put your operations in motion.
We build custom mobile applications that connect teams, extend operational visibility, and keep data moving where desks do not go.
Where web applications fall short.
Web applications are excellent, but they require a stable browser context, continuous connections, and have limited hardware access.
Offline workflow requirements
Web apps require an active internet connection, leaving field teams blocked in remote sites.
Device features required
Standard websites cannot easily access camera barcode scanning, Bluetooth sensors, or hardware APIs.
Field and deskless teams
Desktop-designed tools are difficult to navigate on mobile devices on the shop floor or delivery route.
Real-time alerts
Without push notifications, critical operational status updates get lost in unread emails.
Mobile app services that scale.
We engineer offline-first layouts and native device connections for active field environments.
Cross-Platform Development
We build responsive mobile applications using React Native, delivering native iOS and Android apps from a single codebase.
Offline-First Design
Apps include localized SQLite databases that cache data, syncing modifications back to your server once connection is restored.
Device API Integrations
Direct access to camera scanner utilities, geolocation coordinates, local storage, and Bluetooth telemetry peripherals.
Real-Time Operational Alerts
Managed notification servers that dispatch instant status warnings and dashboard updates directly to users.
Mobile applications built for operational environments.
Since 2008, Letter B has engineered mobile frameworks tailored for logistics, retail inventory, non-profit workflows, and field coordinates.
Listen first
We shadow your teams in the field to understand their operational environments before writing code.
Design for real use
Large touch targets, high contrast, and simple structures optimized for rapid shop-floor input.
Build for longevity
Clean native components, optimized data synchronization, and robust security frameworks.
Uptime support
Continuous performance monitoring, operating system patch updates, and feature upgrades.
A structured mobile delivery process.
We guide your organization through a structured, risk-mitigated delivery cycle from initial discovery to continuous operations.
Map the Workflow
We analyze your on-site procedures, device requirements, and field connectivity constraints.
- On-site workflow observation
- Device profiling audit
- Network latency reports
Establish the UI/UX
We model interfaces, offline sync models, and screen layouts for your review.
- High-fidelity mobile wireframes
- Offline synchronization scheme
- Navigation workflow prototype
Build the Codebase
We develop your native applications, connect database APIs, and publish to test environments.
- Cross-platform React Native code
- Local SQLite caching schema
- API integration layer
Stabilize & Launch
We publish to private enterprise or public app stores, configure alerts, and support onboarding.
- App Store & Play Store cataloging
- Push notification keys setup
- Team onboarding session
From clipboard forms to live database updates.
A distributed inspection group used paper clipboard forms to record equipment integrity, manual scanning, and desktop spreadsheets for reporting.
Before
Lost worksheets delayed inspections, status reports took weeks to consolidate, and offline locations left inspectors without catalog access.
After
A custom cross-platform mobile application supporting camera scanning, local cache sync, and GPS timestamps, transmitting data instantly to the back-office dashboard.
The offline capability changed everything. Our field teams scan parts, log details in remote warehouses, and the sync triggers automatically without code failures.— Logistics Mobile Solution feedback
Questions about mobile app development.
