Frequently Asked Questions

How much does mobile app development cost?

Mobile app development at UniqueSide starts at $8,000. One React Native codebase for both iOS and Android.

Do you build for both iOS and Android?

Yes. We use React Native to build one codebase that ships to both the App Store and Google Play. Production-ready on day 15.

How long does it take to build a mobile app?

We ship production-ready mobile apps in 15 days. App Store and Google Play submission included.

A note on our 15-day timeline

Our 15-day delivery applies to a focused MVP or prototype with core features. For example, a SaaS dashboard with auth, billing, and a core workflow can ship in 15 days. A full-scale product with complex integrations, multi-role permissions, and custom reporting will take longer. Most real-world applications fall somewhere in between. We scope every project individually and give you an honest timeline before we start. The goal is always the same: ship fast without cutting corners.
