Should I build a native or cross-platform mobile app?
Cross-platform frameworks such as React Native and Flutter let one codebase run on iOS and Android, cutting cost and time to market for most apps. Native development in Swift or Kotlin is best when you need heavy device-level performance, advanced graphics or deep platform features.
We have shipped fitness, transport, events, music and on-demand service apps used every day. We design and build mobile apps that feel native, work offline and scale with your user base.
With React Native and Flutter we deliver iOS and Android from one codebase, and go fully native when performance demands it.

Our senior teams combine proven frameworks, reusable accelerators and hands-on engineering to deliver results at speed and scale.

How much does it cost to build a mobile app?
Cost depends on features, platforms and integrations. A focused MVP is far more affordable than a full-featured product; we provide a detailed estimate after a short discovery.
How long does it take to build an app?
Most MVPs launch in 10 to 16 weeks, including design, development, testing and App Store submission.
Do you publish the app to the App Store and Google Play?
Yes. We handle store listings, compliance reviews and submission, under your developer accounts so you retain ownership.
Can you add AI features to my mobile app?
Yes. We add assistants, recommendations, voice input and image recognition using cloud or on-device models.
Do you maintain apps after launch?
Yes. We provide OS-update compatibility, bug fixes, monitoring and feature development on flexible plans.
