Custom Mobile App Development for iOS and Android
Secure, scalable and user-friendly mobile apps for your customers, teams and new digital products.
Build secure, scalable, and user-friendly mobile applications that help businesses improve customer experiences, streamline operations, and launch new digital products. We help organizations plan, develop, integrate, test, and maintain mobile applications using technologies selected to fit their business and technical requirements.
- Native iOS and Android apps, or one cross-platform codebase
- API, cloud and enterprise system integration
- Testing, app store release and ongoing maintenance

Overview
What is custom mobile app development?
Custom mobile app development is the planning, design, building, testing and release of an application made for your users and processes, rather than adapted from an off-the-shelf product. It covers the app people install on iPhone, iPad and Android devices, and the APIs, cloud services and integrations that make the app useful.
We build native iOS and Android apps and cross-platform apps. The right approach depends on your requirements, performance needs, device features, integrations, budget and how the app will be maintained over time, so we recommend it during discovery rather than starting from a fixed framework.
Who it is for
- Businesses launching a new customer-facing app or digital product
- Organizations giving field, sales or operations teams a mobile tool
- Companies whose existing app is unstable, outdated or hard to change
- Teams that need a mobile front end for an existing platform or API
How is this different from Web Development? Mobile App Development delivers installable apps for iOS and Android that can use device features such as the camera, location, notifications and offline storage. Web Development focuses on websites, portals and browser-based applications.
Business challenges
Problems a mobile app can solve
- Customers expect self-service on their phoneBookings, orders, account updates and support requests still depend on calls, email or a desktop website.
- Field teams work from paper or spreadsheetsInspections, deliveries and service visits are recorded later and re-typed, which delays work and introduces errors.
- Data is captured too latePhotos, signatures, locations and readings collected on site do not reach your systems in time to act on them.
- An existing app holds the business backCrashes, poor reviews, outdated libraries or a codebase nobody wants to change make every release risky.
Intended outcomes
- A simpler way for customers and staff to complete tasks on mobile
- Faster, more accurate data from the field into your business systems
- An app your team can release, update and extend with confidence

Choosing an approach
Native vs cross-platform app development
Both approaches can produce high-quality apps. The better choice depends on what your app needs to do and how you plan to run it.
Native development
Separate apps for iOS (Swift) and Android (Kotlin), each built with the platform’s own tools.
- Heavy use of device hardware, sensors or background processing
- Demanding performance, graphics or real-time features
- Early access to new platform capabilities
- An app that targets only one platform
Cross-platform development
One shared codebase for iOS and Android using a framework such as Flutter or React Native.
- The same features and design on both platforms
- A faster path to launching on iOS and Android together
- Business, content and form-based apps
- One team maintaining a single codebase
How we recommend a technology
- Functional requirements and the device features the app needs
- Performance, offline and security requirements
- Integrations with your APIs, cloud services and enterprise systems
- Budget, timeline and whether you need one platform or both
- Long-term maintainability and the skills of the team that will support it

FAQs
Mobile app development FAQs
How much does it cost to develop a mobile app?
Cost depends on the number of screens and features, whether you need iOS, Android or both, native or cross-platform development, integrations with existing systems, design complexity, and security and compliance requirements. We estimate after a short discovery, and a defined-scope project can be quoted at a fixed price.
How long does mobile app development take?
Timelines depend on scope, design and content readiness, integrations, testing needs and app store review. Discovery defines the first release and a realistic schedule. Many teams launch a focused first version and add features in later releases.
Should we build for Android or iOS first?
It depends on where your users are. Customer apps often need both platforms; internal apps can follow the devices your organization uses. Your website analytics, customer data and target markets usually settle the question, and cross-platform development can make launching on both practical.
What is the difference between native and cross-platform development?
Native apps are built separately for each platform, with Swift for iOS and Kotlin for Android, and give the most direct access to platform features and performance. Cross-platform frameworks such as Flutter or React Native share most of the code between iOS and Android, which can reduce effort for many business apps. We recommend an approach after reviewing performance, device features, integrations, budget and long-term maintenance.
Can the app connect to our existing systems?
Usually, yes, where those systems offer APIs or can be integrated securely. Apps commonly connect to ERP, CRM, identity providers, payment gateways and internal databases through a secure API layer. See API & System Integration.
How do you approach mobile app security?
Security is planned from discovery: secure sign-in, encrypted data in transit, careful handling of data stored on the device, least-privilege access to backend APIs and regular dependency updates. Security checks are part of the test plan, and specific compliance requirements are agreed at the start of the project.
Do you publish the app to the App Store and Google Play?
We prepare release builds, store listings and submission assets and support you through review. Apps are usually published under your own developer accounts so you keep control. Approval decisions are made by Apple and Google, so review times can vary.
Do you maintain the app after launch?
Yes. Software Maintenance & Support covers bug fixes, compatibility updates for new iOS and Android versions, dependency and security updates, monitoring and planned enhancements.
Can you add AI features to a mobile app?
Where they serve a clear purpose, such as conversational assistants, document or image recognition, or recommendations. These features usually run through secure backend services. See AI/ML Integration Services.
