Mobile App Development

iOS, Android and cross-platform apps that users keep — designed, built, published and supported.

Your customers live on their phones. Creensight designs and builds mobile apps that are fast, intuitive and reliable — and connects them to secure back ends that scale.

We build cross-platform apps with React Native or Flutter when you want one codebase for iOS and Android, and native Swift/Kotlin when performance or device features demand it.

What we deliver

Cross-platform apps

React Native and Flutter apps with one codebase, native performance and a consistent experience on iOS and Android.

Native apps

Swift and Kotlin for apps that need deep device integration, heavy graphics or maximum performance.

Back end & APIs

Python or Node.js APIs, authentication, payments, real-time features and admin panels.

Offline-first

Local storage and sync so field teams can keep working without a connection.

Store publishing

App Store and Google Play listings, screenshots, privacy labels, review handling and release management.

Analytics & engagement

Crash reporting, product analytics, push notifications and in-app messaging.

Engagement models

Fixed-scope project

Clear scope, milestones and price. Best for well-defined requirements.

Dedicated developer / team

Developers who work only on your project, communicate with you directly, with task tracking. Scale up any time.

R&D / feasibility

A short paid study to research requirements and check feasibility before you invest in a full build.

Frequently asked questions

How much does a mobile app cost?
It depends on features, platforms and integrations. A focused MVP usually costs far less than a feature-rich platform — try our cost estimator on the Services page or ask for a quote.
Native or cross-platform?
Cross-platform suits most business apps and saves cost; native is better for heavy graphics, complex device features or maximum performance.
Do you publish the app for us?
Yes. We prepare the store listings and handle submission under your developer accounts.
Can you take over an existing app?
Yes, after a code audit we can maintain, fix and extend apps built by other teams.
