Which Platform Should You Build For?
No platform is universally better — the right choice depends on your audience and product
Android
Large device ecosystem and Google Play distribution. Often the right starting point when your audience skews Android-first, as in much of the Indian market.
What is Mobile App Development?
Mobile app development is the process of designing, building and launching software for Android and iOS devices — combining UI/UX design, native or cross-platform development, backend and API integration, and ongoing maintenance to turn an idea into a working product that runs on a phone.

Flutter is Xigmapro's primary technology for cross-platform mobile development — one codebase targeting both Android and iOS. It can be a strong fit thanks to shared development effort, faster iteration, consistent UI across platforms, native integrations, straightforward API integration, and a scalable architecture as your app grows.
Flutter isn't always the right technology — highly performance-critical or deeply platform-specific apps sometimes call for native development instead. We'll recommend based on your actual requirements.
Learn More About FlutterCustom Mobile App Development
Custom applications are appropriate when off-the-shelf solutions can't meet your business requirements. We build custom UI/UX, backends, APIs, authentication, role-based access, payments, notifications, location features, chat, bookings, subscriptions, analytics, admin dashboards, third-party integrations and AI features — combined however your specific product needs them.
AI-Powered Mobile App Development
AI can add real value to a mobile app — chatbots, assistants, document and image analysis, voice features, recommendations, personalization, AI-powered search, content generation, OCR, predictive features, AI agents and workflow automation. AI should be added when it solves a real product or business problem, not merely as a marketing feature.
How Much Does It Cost to Build a Mobile App?
Answer a few questions to see an indicative complexity level
Mobile app development at Xigmapro starts from ₹60,000. This is an indicative complexity level, not a fixed quotation — actual cost depends on your exact requirements.
How Much Does App Development Cost in Kolkata?
Mobile app development cost in Kolkata depends on the app's features, platforms, backend, integrations, UI/UX, security requirements and complexity. Xigmapro's mobile app development services currently start from ₹60,000.
The main factors that affect the final price: platform, UI/UX, backend, authentication, payments, admin panel, APIs, notifications, AI, third-party integrations, testing, deployment and maintenance.
How Long Does It Take to Build an App?
Simple apps can move faster than complex apps, while enterprise and AI-heavy applications require more planning and development.
Timelines depend on the number of screens, features, platforms, backend, API integrations, custom UI, AI, admin panel, testing and app store requirements.
Get an App Timeline EstimateMVP or Full-Featured App?
Both are valid starting points — the right one depends on your stage and goals
MVP
- Faster validation of your core idea
- Focused feature set
- Lower initial investment
- Real user feedback before building more
- Room for future expansion
Full Product
- More features from day one
- More workflows covered
- More integrations built in
- Larger initial scope
- Longer development timeline
For many startups, validating the core product before building every feature can reduce unnecessary development. If your requirements are already well understood — an internal enterprise tool, for example — a fuller build from the start can make sense.
Plan Your MVPShould You Build a Custom App?
Existing SaaS, no-code, and custom development each fit different needs
| Existing SaaS | No-Code / Low-Code | Custom Mobile App | |
|---|---|---|---|
| Setup speed | Fastest | Fast | Slowest |
| Cost | Subscription-based | Low upfront cost | Higher upfront investment |
| Customization | Limited to what the SaaS offers | Limited by the platform's building blocks | Unlimited — built exactly to spec |
| Ownership | You don't own the product | Partial — depends on the platform | You fully own the product |
| Scalability | Depends on the vendor's limits | Can hit platform limits at scale | Built to scale with your requirements |
| Best for | Standard, well-solved problems | Simple internal tools, quick prototypes | Unique workflows and products |
Custom development tends to make sense when you have:
Native vs Cross-Platform Development
The right approach depends on your product's requirements
| Native Development | Cross-Platform (Flutter) | |
|---|---|---|
| Performance | Best possible, direct platform access | Very good for most apps, occasional edge cases need native modules |
| Development effort | Separate codebase per platform | One shared codebase for Android and iOS |
| UI consistency | Matches each platform's native conventions | Consistent look across platforms by design |
| Platform-specific features | Full, immediate access to new OS features | Usually available, sometimes with a short delay |
| Maintenance | Two codebases to maintain | One codebase to maintain |
| Cost | Higher — duplicate work across platforms | Lower — shared development effort |
| Time to market | Slower for multi-platform launches | Faster for multi-platform launches |
| Best use cases | Performance-critical or platform-exclusive apps | Most business, ecommerce and consumer apps |
Which approach is right for your app?
Most business, ecommerce and consumer apps are well served by cross-platform development — it covers both platforms faster and at lower cost. Native development is worth the extra investment when your app is performance-critical (heavy graphics, real-time processing) or needs to be first to support brand-new platform-specific features. We'll recommend based on your actual requirements, not a default preference.
Android vs iOS App Development
Where to start depends on your audience, not a universal rule
| Android | iOS | |
|---|---|---|
| Audience | Broad, price-sensitive, dominant in markets like India | Concentrated in higher-income segments and specific regions |
| Devices | Wide range of manufacturers and screen sizes | A smaller, more controlled set of Apple devices |
| Development | More device fragmentation to account for | More consistent hardware, fewer device variations |
| Testing | Broader device/OS-version testing matrix | Narrower, more predictable testing matrix |
| Distribution | Google Play, faster review process | App Store, stricter review guidelines |
| Monetization | Often lower average revenue per user | Often higher average revenue per user |
| Platform requirements | Google Play Developer account | Apple Developer Program membership, macOS for builds |
Start with Android if your audience is India-focused or price-sensitive. Start with iOS if your audience is concentrated in iOS-heavy markets or you're targeting higher-spending segments. Start with both when your product needs both audiences from launch — a cross-platform framework like Flutter makes this practical without doubling development effort.

Mobile Apps Need More Than a Mobile Interface
A mobile app you can tap on your phone is only the visible part. Behind it sits a backend that stores and processes data, a database, APIs that connect the app to that backend, authentication to identify users, an admin panel to manage the app's content and users, notifications to bring users back, and analytics to understand how the app is actually being used. Understanding this helps non-technical founders scope a realistic project — "just the app" is rarely the whole picture.
Mobile App Security
A production-grade app should address:
App Launch & Deployment
Getting an app live involves Android application packaging and Google Play deployment, iOS application deployment and App Store requirements, production configuration, API configuration, thorough testing, and release management for future updates. Apple and Google control their own store review processes — we can't promise a specific approval timeline, but we prepare submissions to meet each store's requirements.
