FAQ

Frequently asked questions.

Everything you need to know before starting your project.

Should I build a native or cross-platform app?

Cross-platform (Flutter or React Native) is faster and more cost-effective for most products; native (Swift/Kotlin) suits performance-critical or platform-specific apps. We recommend the right approach after scoping.

How long does it take to build a mobile app?

A production-ready MVP typically ships in 10–16 weeks. Larger marketplace app suites with customer, vendor and delivery apps take longer and are delivered in phases.

Do you publish to the App Store and Google Play?

Yes — we handle the full release process, including store listings, review compliance, and post-launch updates and monitoring.

Can you build customer, vendor and delivery apps on one backend?

Absolutely — that is our specialty. We build role-specific apps that share a single backend so inventory, orders and data stay perfectly in sync.
