Wecraftmobileappsthatpeopleactuallyuse.
By Sivis is an independent studio designing and building iOS, Android, and cross-platform apps for ambitious teams.
Three disciplines, one obsession with quality.
iOS Development
Native Swift and SwiftUI apps tuned for the platform.
Android Development
Kotlin and Jetpack Compose, built for performance.
Cross-Platform
React Native and Flutter for shared codebases.
A calm process, built around shipping.
Discover
We start with workshops, audits, and conversations. Goals get sharp, constraints surface, decisions get easier.
Design
Wireframes, prototypes, motion studies. We pressure-test the experience before a single line of production code.
Build
Weekly builds, native performance, predictable releases. You see progress instead of hearing about it.
Launch
Store submission, telemetry, on-call support. We stay close after release because that is when the real work starts.
Let's build something.
