Mobile apps built natively, by people who know when not to

Senior engineers building for iPhone and Android since the app stores opened. We pick the approach your app needs, then we tell you why.

Etlon builds mobile apps natively: Swift and SwiftUI on iOS, Kotlin and Jetpack Compose on Android. Native is our default because it produces faster apps, cleaner store reviews, and fewer late-project surprises. But the choice between native and cross-platform is an engineering decision, not a religion, and we make it based on your app. If it is a straightforward front end over an API with no heavy performance, offline, or hardware demands, cross-platform can be the cheaper right answer, and we will say so. If your app depends on speed, background behavior, subscriptions, or the platform's newest capabilities, native pays for itself. Either way, you get a plain-language recommendation with the tradeoffs written down before any code is written.

Pick your platform

Two native practices, one team

Platform

iOS App Development

Swift and SwiftUI apps engineered to pass App Store review, bill subscriptions correctly, and work offline. TestFlight builds from the first weeks and an automated release pipeline when you launch.

Platform

Android App Development

Kotlin and Jetpack Compose apps tested on the real device landscape: old hardware, low RAM, and manufacturer skins included. Staged rollouts and background work that survives aggressive battery managers.
