Mobile applications we build
The product shape follows the job it needs to do.
The audience, workflows, systems and operating context determine the application—not a preselected template.
Business & enterprise apps
Mobile access to operational workflows, information and approvals away from a desk.
Customer self-service apps
Account, service, booking and support experiences organized around customer needs.
Booking & service apps
Scheduling, appointment management and service interactions with clear confirmation states.
Connected mobile products
Applications that exchange data with agreed APIs, platforms and business systems.
App modernization
Improve an existing product’s user experience, maintainability and technical direction.
Platform strategy
The right mobile approach for the product.
Platform decisions should follow the users, product requirements, performance needs, integrations, team constraints and long-term maintainability.
Native iOS development
Considered when Apple-platform conventions, device capabilities, performance needs or an iOS-first audience justify a dedicated implementation.
Native Android development
Considered when Android-specific behavior, device diversity, integrations or audience needs make a dedicated approach appropriate.
Cross-platform development
Considered when a shared implementation across iOS and Android fits the experience, integrations, delivery constraints and maintenance model.
Native and cross-platform: what discovery evaluates
- Performance & device access
- A native approach can provide the most direct platform access. Cross-platform capability depends on the selected framework and required features.
- Shared implementation
- Cross-platform delivery may share more code. Native products typically maintain separate platform implementations.
- Experience requirements
- Both approaches can support strong experiences; platform-specific interaction and visual requirements affect the decision.
- Delivery & maintenance
- Team capability, release cadence, testing scope and long-term ownership matter as much as initial delivery speed.

ITGS internal concept
Self-initiated concept · Not client work · Illustrative data
Focused journeys
Keep the primary task clear, from choosing a service to reviewing the details.
Clear feedback
Show what happened after an action, with confirmation and the next useful step.
Consistent interactions
Use familiar controls and language across selection, confirmation and management.
Designed for the thumb
Keep frequent actions clear and comfortably reachable where the layout allows.
Product strategy & discovery
Build the right app before building the app right.
Development should begin after the essential product decisions are understood. Discovery connects the business need with the users, platforms, systems and release plan.
Discovery considers
- Business objective
- Target users & problems
- Feature priorities
- Systems & integrations
- Platform requirements
- Security & privacy needs
- Analytics requirements
- Release constraints
Potential planning outputs
- Product brief
- Prioritized feature scope
- User journeys
- Platform recommendation
- Technical direction
- Delivery roadmap
Final outputs depend on the agreed discovery scope.
Mobile UX & product design
Mobile UX designed around real behavior.
A mobile experience should respond to context, touch, interruptions and platform expectations. It should not feel like a desktop interface compressed into a smaller screen.
User flows
Map the steps people need to complete important tasks.
Information architecture
Organize content and actions around mobile priorities.
Wireframes
Test structure before investing in detailed interface work.
Interactive prototypes
Review key journeys and interaction states before development.
Platform conventions
Respect familiar iOS and Android behaviors where they improve clarity.
Accessible interaction
Consider readable content, focus, labels, contrast and touch targets.
Product quality
Built for real-world mobile use.
Quality covers more than a successful build. It includes how the app behaves across users, devices, networks, permissions and future releases.
Performance
Plan for responsive interaction, efficient data use and appropriate startup behavior.
Reliability
Handle expected errors, interrupted tasks and changing connection conditions clearly.
Security & privacy
Consider authentication, authorization, secure storage, encrypted communication and permissions.
Accessibility
Use relevant platform accessibility practices and inclusive interaction patterns.
Device compatibility
Define an agreed support matrix across relevant devices, screen sizes and OS versions.
Maintainability
Use structured implementation, documentation and release practices that support future work.
For regulated or sensitive products, applicable security, privacy and compliance requirements must be identified during discovery. The architecture can be designed to support agreed requirements; no universal compliance claim is made.
Backend, APIs & device features
Mobile apps don’t live in isolation.
A useful mobile product often depends on secure data, business systems and device capabilities. Each connection is assessed for access, documentation, security and operational ownership.
APIs & business systems
Connect with documented APIs, web platforms, CRM, ERP, booking or other agreed systems.
Authentication
Plan sign-in, roles, permissions and secure session behavior around the product requirements.
Notifications & live updates
Use push notifications or real-time data where they provide a clear user benefit.
Device capabilities
Consider location, maps, camera, files or other device features when the use case requires them.
Backend & cloud services
Scope application logic, storage and infrastructure needed to support the mobile experience.
Offline-aware experiences
Where required, plan caching, synchronization, recovery and conflict behavior for unreliable connections.
Technology
Technology chosen around the product.
Specific frameworks, backend services and cloud providers are confirmed against the product and the team’s verified delivery capability. Technology is not selected to fill a logo wall.

- Screen-size testing
- OS-version testing
- Integration testing
- Regression testing
- Network-condition testing
- Accessibility checks
- Release checks
Release preparation
From development to App Store and Google Play.
Where included, ITGS can prepare and support the submission process across build configuration, signing, store assets, privacy information, metadata and review responses. Apple and Google control approval, so approval is never guaranteed.
Client-controlled production accounts
Critical production assets should use appropriately controlled App Store Connect, Google Play Console, cloud and third-party accounts where contractually agreed. Access, responsibilities and handover are documented before release.
After release
Launch is the beginning.
Mobile platforms, dependencies and customer needs continue to change. An agreed maintenance or improvement plan can be scoped separately around the product’s operational needs.
- OS compatibility updates
- Dependency and security updates
- Crash and issue review
- Bug fixes and performance work
- Feature releases
- Product analytics review
- Store updates
Measure the product after launch
Activation, engagement, funnels, crashes, feature use and conversion events can be considered before release where analytics are included. No improvement outcome is guaranteed.

Mobile app development FAQ
Before we begin.
Questions that clarify platform choice, scope, ownership, testing, release and ongoing responsibilities.
How much does mobile app development cost?
Cost depends on the platforms, feature scope, product design, backend work, integrations, security needs, testing matrix and release support. A useful estimate follows discovery of those requirements.
How long does it take to build a mobile app?
Timing depends on product complexity, decision speed, integration readiness, platforms, testing needs and store preparation. The agreed scope should define phases, review points and an indicative schedule.
Do you build for both iOS and Android?
The platform plan can include iOS, Android or both when those platforms match the target audience and product requirements. The exact implementation approach is confirmed during discovery.
Should we choose native or cross-platform development?
That depends on the app’s device features, experience needs, performance requirements, team constraints and future plans. The options are compared during discovery without treating either approach as universally superior.
Can you take over or modernize an existing mobile app?
An existing product can be assessed for user experience, codebase condition, dependencies, backend services, release setup and ownership. The assessment determines whether targeted modernization or replacement is the more responsible direction.
Can you connect the app to an existing system?
Potential integrations depend on the system’s interfaces, documentation, access, data model and security requirements. Any connections are reviewed and agreed as part of the scope.
Can ITGS build the backend and APIs?
Backend or API work can be included where it is supported and agreed. Requirements, hosting, data ownership, security boundaries and ongoing responsibilities must be defined in the written scope.
How is the application tested?
Testing can cover functionality, agreed physical devices, screen sizes, OS versions, integrations, regression, network conditions, accessibility and release configuration. The project defines a realistic support matrix rather than claiming every device is tested.
What does App Store and Google Play submission involve?
Submission can involve developer accounts, signing, release builds, store assets, privacy information, metadata and review responses. ITGS can prepare and support the agreed submission process, but Apple and Google decide approval.
Who owns the source code and product assets?
Ownership and access can differ by engagement. The contract should define source code, design files, repositories, cloud environments, developer accounts, documentation and third-party licensing before work begins.
Can analytics and crash monitoring be included?
Product analytics, conversion events, crash reporting and operational monitoring can be considered where they are supported and included in scope. Measurement requirements are best agreed before release.
How are updates and maintenance handled after launch?
A maintenance or improvement plan can be scoped around OS compatibility, dependencies, security updates, issues, store releases and feature development. Availability, responsibilities, response expectations and commercial terms require a separate agreement.
