What types of mobile apps does Collatzinc develop?

Collatzinc develops native iOS apps using Swift, native Android apps using Kotlin and cross-platform applications using React Native and Flutter. The team also builds enterprise mobile solutions, customer-facing apps and IoT-connected mobile applications.

Does Collatzinc build its own mobile products?

Yes. Collatzinc designed and shipped Zysh — a productivity app for iOS and Android — built entirely in-house on native KMMM with Jetpack Compose and SwiftUI. Zysh is live on both the App Store and Google Play.

Should I choose native or cross-platform development?

Native apps deliver maximum performance and platform integration. Cross-platform solutions using React Native or Flutter reduce development time and cost while covering both iOS and Android from a shared codebase. Collatzinc assesses the right approach based on your performance requirements, budget and user experience goals.
