Mobile app development for iOS and Android
Apps built to perform, feel native, and last
Whether you need a native app for a single platform or a cross-platform app for both iOS and Android, we provide custom mobile app development that performs well, feels native, and is supported long after launch, through Fixed Price Projects for larger initiatives and Continuous Monthly Development for ongoing improvements.
Choosing the right approach for your app
Not every app should be built the same way. The right approach depends on your platforms, your timeline, and what your app needs to do.
Native iOS or native Android
Build specifically for one platform using Swift (iOS) or Kotlin (Android). The right choice when you're targeting a single platform, need the latest platform-specific features immediately, or require maximum performance for graphics-intensive or real-time apps.
Cross-platform with React Native or .NET MAUI
Build once and deploy to both iOS and Android from a single codebase. The right choice when you need both platforms, want faster time to market, or your app is more data- and workflow-driven than hardware-intensive.
If you're not sure which approach fits your project, tell us what you're trying to build and we'll recommend honestly, including telling you if a simpler web application would serve you better than a native app.
What we build
Consumer and client-facing apps
Shopping apps, booking apps, content and community apps, client account and loyalty apps.
Business and productivity apps
Field service tools, internal dashboards, workflow and approval apps, sales enablement tools.
Apps connected to existing systems
Apps that read from and write to your ERP, CRM, ecommerce platform or custom backend, native or cross-platform, built to integrate with what you already run.
AI-powered apps
Apps with built-in chat assistants, personalization, intelligent search, or on-device and cloud-based AI features.
App support and Continuous Monthly Development
Send tasks whenever they arise. With Care, everything runs in writing at one fixed monthly price: no estimates to approve, no cost overruns.
Care Plus gives you everything in Care at its own fixed monthly price, plus up to two hours of meetings per month with a Project Manager or any 1902 Software expert (for planning, advice and technical discussion), up to two ongoing tasks at a time, and up to two developers working on your tasks at the same time.
Care Ultimate is for ongoing engagements, often across multiple systems, that need close collaboration: a fixed price for every task or group of tasks, approved by you before work begins, people with the right expertise added to your project as your needs grow, and meetings with any 1902 Software expert whenever you need them (billed at the going project management rate for the actual time spent).
Typical work includes:
- Bug fixes
- New functionality
- OS version updates
- UI and UX improvements
- Performance optimization
- API integrations
- App Store and Google Play releases
- Push notification improvements
- AI implementation
- Ongoing technical support
Fixed Price Projects
For a single, well-defined app project (a new build, a major upgrade) you get one agreed price for the whole thing, fixed before work begins.
Typical projects include:
- New iOS, Android, or cross-platform applications
- Major app redesigns
- Backend integrations
- App modernization and framework migrations
Large projects typically start with a Project Scoping phase at an agreed, prepaid fixed price. The purpose is to precisely define what will be built and to establish the final price. This ensures full clarity for both you and us before development begins.
Taking over existing apps
Many of our clients originally worked with another mobile app development company.
We regularly take over existing iOS, Android, React Native, and .NET MAUI applications, review the existing implementation and continue development with minimal disruption to your business.
From idea to app store
Discovery and planning
We start by understanding your business goals, target users, and app requirements, including which platforms and approach make sense.
UI/UX design
Our designers create interfaces following each platform's design guidelines while expressing your brand.
Development
Native or cross-platform development, with regular progress updates and working builds to test as features are completed.
Quality assurance
We test across devices, screen sizes and OS versions before anything reaches the app stores.
App Store and Google Play launch
We handle submission, compliance, and store listing optimization for both platforms.
Ongoing support
The same team that built your app supports it afterward, OS updates, new features, and store resubmissions, typically through Continuous Monthly Development.

Commonly asked questions
Should we build native apps or a cross-platform app?
It depends on your platforms, timeline and requirements. Native development (Swift for iOS, Kotlin for Android) gives you the best performance and fastest access to new platform features, but means maintaining two codebases. Cross-platform development (React Native or .NET MAUI) means one codebase for both platforms, which is faster and more cost-effective when your app doesn’t need deep platform-specific features. We’ll recommend honestly based on what you’re building.
Do you provide ongoing app support?
Yes. Continuous Monthly Development is our primary service for ongoing app development and support, OS updates, new features, bug fixes and store releases, without requesting a quotation for every individual task.
Can you take over an app built by another company?
Yes. We regularly take over existing iOS, Android, React Native and .NET MAUI apps, review the existing implementation and continue development with minimal disruption to your business.
How long does it take to build and launch an app?
It depends on complexity and platform choice. Simple apps can launch in 2-3 months; complex apps with custom features and backend integrations typically take 4-6+ months. We provide a specific timeline as part of the project scope after understanding your requirements.
What technologies do you use?
Swift and Objective-C for native iOS, Kotlin and Java for native Android, React Native and .NET MAUI for cross-platform development. We choose the right technology for your specific requirements rather than defaulting to one approach.
How do you use AI in your app development work?
Our developers, designers, and testers work with modern AI-assisted tools throughout app development, from planning and design to coding and testing. Every app is still reviewed, tested and verified by experienced developers and QA testers before it ships.
