FAQ

Frequently asked questions

How much does it cost to build an app?

A well-scoped MVP typically costs $25,000–$75,000. Complex apps with advanced features run higher. We quote fixed prices after scoping.

How long does app development take?

Most MVPs ship in 10–16 weeks. Larger products are phased over several quarters.

Should I go native or cross-platform?

Cross-platform (React Native/Flutter) saves 30–40% on cost when you need both iOS and Android. Native is best for heavy performance or hardware needs.

Do you handle App Store submission?

Yes — accounts, screenshots, metadata, and review management are all included.

What about app maintenance?

We offer monthly maintenance plans covering OS updates, bug fixes, and monitoring.
