Mobile ApplicationDevelopmentBuilt for the place where the work happens.
Native, cross-platform and progressive web applications engineered around field, workforce and customer use.
KAPAT engineers mobile applications for people who work away from a desk — field staff, delivery teams, inspectors, sales, customers — with offline capability, background synchronisation and a backend shared with the rest of the business system.

When This Service Fits
When the work happens on a phone or tablet.
A mobile application is justified when the people doing the work are not at a desk, when the device itself matters — camera, GPS, barcode scanning, signatures — or when the application must keep working without a reliable connection. If none of those apply, a responsive web application is often the simpler choice.
Common scenarios — not every organisation has all of these.
- 01Field teams record inspections, readings, deliveries or service visits at customer sites.
- 02Work continues in warehouses, plants, farms or basements where connectivity is intermittent.
- 03The task needs the camera, barcode or QR scanning, GPS location, signature capture or push notifications.
- 04Staff currently fill in paper forms on site and re-enter them at the office later.
- 05Customers should be able to track orders, book services, make payments or raise requests from their phone.
- 06Sales or account teams need customer, stock or pricing information while travelling.
- 07Supervisors need to approve, assign or reschedule work from wherever they are.
- 08A web platform already exists and needs a companion app for the people who are rarely at a desk.
- 09Devices are organisation-owned and managed, and the application must be distributed outside public stores.
- 10Timely data from the field — status, proof, location — matters to the rest of the operation.
Decision Support
Native, cross-platform or progressive web app.
The platform decision shapes cost, capability and maintenance for years. It should be made on the requirements of the application — not on a default preference.
Native (Swift / Kotlin) fits when
- Deep use of device hardware or platform-specific features is central
- Performance-sensitive work such as media, mapping or real-time processing
- Only one platform is genuinely needed
- Tight integration with platform services and device management
- The best possible platform-native experience is the priority
Cross-platform fits when
- Both iOS and Android are needed from one codebase
- The application is mostly forms, lists, workflows and data
- One team must maintain the app alongside a web application
- Time to first release across both platforms matters
- Offline and sync logic should be written once
- Hardware needs are standard: camera, location, scanning, notifications
A progressive web app fits when
- Users are mostly connected and use the app occasionally
- App store distribution is unnecessary or undesirable
- The existing web application should simply work well on phones
- Hardware needs are minimal
- Installation friction must be as low as possible
- Budget favours one responsive codebase
These are general patterns. Many systems combine them — a cross-platform field app for staff, a responsive web application for the office and a PWA for customers — on one shared backend. KAPAT helps settle the platform decision during discovery, before engineering begins.
Typical Software Opportunities
Types of mobile application KAPAT engineers.
Representative categories of mobile system, shown as capability areas rather than as a list of completed projects. The specific shape of any application is defined during discovery.
01
Field Service & Inspection Apps
Job lists, checklists, readings, photos, signatures and status updates captured on site and synchronised when connectivity returns.
Potential capability
02
Mobile Workforce Tools
Applications for delivery, logistics, maintenance and sales staff: schedules, routes, proof of work, stock lookups and communication with the office.
Potential capability
03
Customer-facing Apps
Ordering, booking, tracking, payments, account management and support — connected to the same backend as the business system.
Potential capability
04
Inventory & Scanning Apps
Barcode and QR scanning for stock receipt, picking, counts, transfers and asset tracking in warehouses, plants and stores.
Potential capability
05
Approval & Supervision Apps
Lightweight applications for managers to review, approve, assign and monitor work from anywhere, with notifications for what needs attention.
Potential capability
06
Data Collection & Survey Apps
Structured capture of observations, samples, measurements and forms in the field — agriculture, research, audits, site visits — with validation at entry.
Potential capability
Engineering Approach
How a mobile application is delivered.
Mobile engineering adds specific concerns to the standard delivery sequence: the platform decision, offline behaviour, device capabilities, distribution and update. Each is settled early because each is costly to change later.
01
Discover
Understand who uses the app, where, on which devices and with what connectivity.
02
Decide Platform
Native, cross-platform or PWA — chosen on requirements, hardware and maintenance.
03
Architect
Offline data model, synchronisation strategy, APIs, security and backend.
04
Design
Interfaces for fast, one-handed, sometimes glove-handed use in real conditions.
05
Engineer
Build the application, backend and sync in verified increments.
06
Validate
Test on real devices, poor networks, interrupted sessions and conflicting edits.
07
Release & Evolve
Store or enterprise distribution, monitoring, updates and ongoing improvement.
Architecture
Architecture principles for mobile applications.
A mobile application is one client of a larger system. The architecture must handle the realities of the device — intermittent connectivity, limited resources, interrupted sessions — while keeping the backend as the single source of truth.
Offline-first where the work demands it
Data needed on site is stored locally, actions are queued, and the application remains usable without signal. Connectivity is treated as a variable, not an assumption.
Deliberate synchronisation
What syncs, when, in which direction and how conflicts are resolved is designed explicitly — including what happens when two people edit the same record offline.
Shared backend, thin client
Business rules and authorisation live in the backend APIs shared with the web application. The app captures, presents and queues; it does not become a second system.
Device capability with fallbacks
Camera, scanning, location and notifications are used where they add value, with graceful behaviour when a permission is denied or hardware is unavailable.
Secure on the device
Local data encryption, secure credential storage, token expiry and remote revocation are designed in, because devices are lost and shared.
Versioned and updatable
APIs are versioned so old app versions in the field keep working, and update paths — store, enterprise, over-the-air — are planned from the first release.
Technology

Data
Quality & Distribution
Technology stacks are selected per project for fit, longevity, the team that will maintain the system and long-term maintainability — never on the basis of a default preference.
Quality & Engineering Discipline
Engineering quality in mobile applications.
Works without signal
The application is tested in airplane mode, on flaky networks and across interruptions, not only on office Wi-Fi.
Sync that does not lose data
Queued actions survive app restarts and device reboots; conflicts are detected and handled by rule, not silently overwritten.
Secure device storage
Local data and credentials are encrypted; sessions expire; lost devices can be cut off from the backend.
Battery and data aware
Background work, location polling and media upload are engineered to respect battery life and metered connections.
Fast in the hand
Interfaces are designed for quick capture in real conditions — large targets, minimal typing, clear state — and profiled on mid-range devices.
Tested on real devices
Behaviour is verified across operating system versions, screen sizes and manufacturer variations, not only on simulators.
Observable in the field
Crash reporting, sync diagnostics and usage monitoring so problems in the field are visible to the team.
Maintained through store cycles
Operating system updates, store policy changes and dependency upgrades are planned for as part of long-term maintenance.
