Mobile App Development
We design and build iOS and Android applications for companies launching customer products, internal field tools, or a mobile extension of an existing platform, from architecture through store release and ongoing evolution.
- React Native
- Native iOS & Android
- Backend & API integration
- Authentication & payments
- App Store & Play Store release
Mobile app development is the design, engineering, and release of iOS and Android applications that solve a defined business problem, whether that's a customer-facing product, an internal operational tool, or a mobile extension of an existing platform. North Tech Labs builds these as product-focused engagements, not just app-store submissions.
Business challenges this addresses
- A web product needs a mobile counterpartCustomers expect a mobile experience, but a web-first product wasn't architected with a mobile client in mind.
- Field staff need a tool that works outside the officeTeams working on-site, in transit, or without reliable connectivity need an application built for that reality, not a scaled-down web page.
- An existing app has become difficult to extendA previous build accumulated technical debt to the point where adding features or fixing bugs takes disproportionately long.
- Store approval and release is unfamiliar territoryGetting an app through App Store and Play Store review, and keeping it there through OS updates, has operational overhead most teams haven't budgeted for.
Capabilities
- Product strategy and scoping for a mobile-first experience
- UX/UI design for iOS and Android
- Offline behaviour and sync logic where relevant
- Push notifications and in-app messaging
- React Native for shared iOS/Android codebases
- Native modules where platform-specific behaviour is required
- Backend and API integration
- Authentication, payments, and maps/location integration
- App Store and Play Store submission and review management
- Analytics and crash reporting integration
- QA across device and OS versions
- Ongoing maintenance and OS-update compatibility
Typical solutions
Examples of the kind of systems this service can build — not a list of completed client projects unless stated otherwise.
- Customer applicationA consumer-facing mobile app extending or replacing a web product's core experience.
- Marketplace appA mobile app connecting buyers and sellers or service providers, with listings, messaging, and transactions.
- Logistics or driver appA field application for drivers or delivery staff, with routing, job assignment, and status updates.
- Field-service appA mobile tool for technicians or field staff to manage jobs, capture data, and report status from the field.
- Booking applicationAn app handling reservations or appointments with real-time availability.
- Membership or community platformA mobile app for a membership-based product or community, with profiles, content, and engagement features.
- FieldFlow Mobile (concept)
- Mobile API gateway
- Task & sync service
- Push notification service
- Primary datastore
Delivery approach
- 1Product strategyWe clarify the core use case, target platforms, and what genuinely needs to be in the mobile app versus the web product.
- 2UX/UI designWe design the interface around mobile interaction patterns, not a resized web layout.
- 3ArchitectureWe decide between React Native and native development per platform based on your actual requirements.
- 4DevelopmentWe build against real devices from the first sprint, not a simulator-only build, so performance and platform quirks surface early instead of at submission time.
- 5QAWe test across representative device and OS versions before submission.
- 6ReleaseWe manage App Store and Play Store submission, including review requirements.
- 7Ongoing evolutionWe maintain compatibility through OS updates and extend the app as your product evolves.
Architecture & engineering considerations
- Offline behaviourLocal data caching and sync logic for the specific scenarios where connectivity genuinely can't be assumed, not added by default everywhere.
- Backend integrationAPI design that serves both the mobile app and any existing web product without duplicating business logic.
- SecuritySecure storage of credentials and tokens on-device, and encrypted communication with backend services.
- ObservabilityCrash reporting and analytics integrated from the first release, not added after problems appear in the wild.
- MaintainabilityA shared React Native codebase where practical, to avoid maintaining two divergent platform-specific apps.
Where this fits
Is this the right fit?
- A good fit when...You need a real product experience on iOS and/or Android, not just a technically-possible wrapper around a website.
- Not a good fit when...The product is mostly content or forms — a mobile-optimised website will serve your users better than a native app shell, and we'll say so.
- Typical engagement shapeAn initial release scoped to a defined core use case, followed by ongoing iteration based on real usage.
Frequently asked questions
Do you build native iOS/Android apps or React Native?
Most engagements use React Native for a single shared codebase across iOS and Android. We use fully native development where a specific platform capability or performance requirement genuinely calls for it.
Can you take over an existing app?
Yes — we review the existing codebase first to give an honest assessment of what can be extended versus what should be rebuilt, rather than assuming a rewrite is always necessary.
Do you handle App Store and Play Store submission?
Yes, submission and review management for both stores is part of the release phase of this service.
