What We Do
01
Native or cross-platform — based on fit
We select native Android with Kotlin, native iOS with Swift, Flutter, or React Native based on performance, UX, maintainability, and speed.
02
Backend built for scale
We design API-first .NET 10 or Node.js backends with auth, data models, integrations, notifications, background jobs, real-time features, and monitoring.
03
Offline-first for field workers
We build apps that work without connectivity — offline data capture, local storage, and sync when connected.
Integrated with your stack
We connect mobile apps to ERP, CRM, commerce, identity, payments, analytics, data platforms, and custom APIs.
05
Security and quality engineered in
We test devices, networks, auth flows, APIs, accessibility, performance, releases, and mobile/API security risk areas.
06
UX designed for mobile
We design mobile-first flows for touch, compact tasks, responsive screens, and real device behavior.

How We Build Mobile Apps
Free consultation & scoping
We discuss product goals, users, platforms, integrations, security expectations, data needs, and operational constraints. Outputs include a high-level architecture brief, delivery approach, and first-scope recommendation. No cost, no obligation.
UX design & prototyping
We design the mobile UX: wireframes, screen flows, and an interactive prototype — approved before development starts.
Iterative development (sprints)
We build in 2-week sprints with backlog refinement, demos, code reviews, device testing, API validation, and delivery checkpoints across mobile, backend, integrations, and QA workstreams.
Backend & integrations
We build backend services on current supported .NET versions, including .NET 10 where appropriate, or Node.js. Work includes API specifications, authentication, integrations, notifications, data services, deployment pipelines, and observability setup.
Testing & deployment
We test on real devices and OS versions, run functional, accessibility, performance, API, and security testing, prepare a release checklist, submit to the App Store and Google Play, and set up CI/CD for future releases.
Launch & support
We launch, monitor, and support the app with ongoing enhancements, OS-version updates, crash monitoring, telemetry, security updates, and roadmap-based improvements.
It starts with a free mobile app consultation. No obligation.
Why Star Knowledge

| AI-enabled mobile experience | Mobile features using AI assistants, summarization, recommendations, image understanding, or workflow automation | Flutter, React Native, or native apps with secure AI service integration through .NET 10 or Node.js APIs |
| Mobile companion to web app | Mobile-first UX connected to the same backend, identity, and data model as the existing web platform | Flutter or React Native for shared delivery; native if platform-specific capabilities dominate |
| Not sure if we need an app or PWA | Discovery-led recommendation based on offline needs, app store requirements, device features, and user behavior | PWA first for lightweight needs; mobile app when offline, push, native UX, smartwatch, or device access is required |

Insights
Gated guide: Mobile app architecture guide — native, cross-platform, backend, security, AI, and wearables
Native and Cross-Platform Mobile Development in 2026
In 2026, the strongest mobile strategy is not tied to a single vendor or framework. Some products need native Android with Kotlin or native iOS with Swift for maximum platform control, device integration, wearable support, or performance. Others are better served by Flutter or React Native for faster cross-platform delivery and shared code. The right choice depends on users, features, performance expectations, offline needs, team skills, backend architecture, security, observability, and long-term maintenance.
01
Native Android with — Kotlin for Android-first products, deep hardware access, enterprise devices, and Wear OS experiences
02
03
React Native for cross -platform apps where JavaScript/TypeScript skills, ecosystem depth, and native module flexibility are important
Do we need a native app or would a PWA work?
PWA if: the experience is informational, lightweight, browser-friendly, and does not need deep device features, reliable push, advanced offline sync, or smartwatch integration. Native or cross-platform mobile app if: you need offline mode, app store presence, push notifications, camera/barcode, GPS, biometric authentication, wearable support, AI-powered mobile workflows, or a polished platform-specific UX. We recommend honestly — sometimes a PWA is all you need.
Frequently Asked Questions
What technologies do you use for mobile apps?
We build native Android apps with Kotlin, native iOS apps with Swift, and cross-platform apps using Flutter or React Native. Backends use current supported .NET versions, including .NET 10 where appropriate, or Node.js, with APIs, authentication, integrations, observability, security testing, AI features, and smartwatch support based on need.
Can you build for iOS AND Android from one codebase?
Yes. Flutter or React Native works well for many single-codebase iOS and Android apps. We recommend native Android with Kotlin or native iOS with Swift when platform performance, device integration, or platform-specific UX is critical.
Can the app work offline?
Yes. We build offline-first apps with local data storage, background sync, and conflict handling for field worker and data capture use cases.
Can you integrate with our ERP, CRM, identity, or business systems?
Yes. We connect mobile apps to ERP, CRM, commerce, identity providers, data platforms, payment gateways, custom systems, and third-party services through backend APIs and integration layers.
How is custom mobile app development different from low-code mobile tools?
Low-code fits simple internal forms and workflows. Custom mobile app development is better for complex UX, offline mode, native device features, performance, customer-facing apps, smartwatch integration, AI features, and long-term scalability.
How much does a mobile app cost?
Costs depend on scope and complexity. App strategy and design runs $10,000–$25,000; standard cross-platform apps run $30,000–$100,000; complex enterprise apps run $80,000–$250,000+. The estimator gives a ballpark; consultation creates a fixed scope.
How long does mobile development take?
A focused internal app may take 6–10 weeks, a standard customer app 3–5 months, and a complex enterprise app 5–8 months. We deliver in 2-week sprints with regular demos.
Do you handle App Store and Google Play submission?
Yes. We manage Apple App Store and Google Play submission, metadata, release notes, screenshots, review requirements, and compliance documentation. For internal apps, we support enterprise distribution.
How do you secure mobile apps and APIs?
Yes. We support releases, crash monitoring, performance tracking, OS-version updates, dependency updates, bug fixes, and roadmap enhancements after launch.
