Tuned Flutter/native builds, native plugins where it counts, and observability baked in (crash reporting, tracing, logs).

UX that converts

Motion, micro-interactions, and accessibility that feel right on both iOS and Android.

Built for growth

Analytics events, deep links, push, and store optimization — plus a backend that scales on Node.js + MongoDB.

What you get

A production-ready Flutter app with a robust Node.js + MongoDB backend, clean architecture, and analytics — ready for v1.0 and beyond.

Flutter single codebase with native plugins for camera, maps, payments, background tasks.

Native iOS (Swift) and Android (Kotlin) for performance-critical features.

Node.js API (Express/Nest) + MongoDB (Atlas) with indexes, aggregations, and structured logging.

Offline-first data, secure storage, and background sync.

Auth (Apple/Google/email) with JWT/refresh tokens and role-based access.

Payments & subscriptions (Stripe or your preferred gateway).

EN/AR localization with full RTL support and store listings in both languages.

FAQs

Flutter or native — what do you recommend?

We default to Flutter for most products to ship faster across iOS & Android. We go fully native in Swift/Kotlin when heavy camera/Bluetooth, ultra-low latency, advanced background execution, or deep platform integrations are core to the experience.

Do you build the backend too?

Yes. We deliver a Node.js API with MongoDB (Atlas) and provide Postman collections, environment templates, and deployment docs.

Can you integrate with our existing services?

Absolutely — REST or GraphQL, payments, auth providers, and 3rd-party APIs.
