Frequently Asked Questions

How much does mobile app development cost?

Simple mobile apps start at 8-12 weeks; complex apps with backend, payments, and integrations are scoped after discovery. We provide transparent estimates based on features and platforms (iOS, Android, or cross-platform).

How long does it take to build a mobile app?

MVPs typically launch in 10-16 weeks. Timeline depends on features, platforms (native vs cross-platform), and backend complexity. We deliver working versions every 2 weeks.

Native vs cross-platform mobile development?

Cross-platform (React Native, Flutter) is faster and cheaper for most apps. Native (Swift/Kotlin) is better for performance-critical features or platform-specific needs. We recommend the best fit for your goals.

Do you handle App Store submission?

Yes. We manage the entire process: app signing, compliance, screenshots, descriptions, and submission to Apple App Store and Google Play Store.

Can you build web apps too?

Absolutely. We build custom web applications, SaaS platforms, and ecommerce sites alongside mobile apps for complete digital solutions.

Do we own the code and IP?

Yes. Repositories are under your organization; you have full ownership and access from day one.
