Questions We Hear Every Week

Native iOS with Swift and SwiftUI, native Android with Kotlin and Jetpack Compose, plus Flutter and React Native for cross-platform work. Every engineer has shipped through store review, not only built in a simulator.
Yes. Native iOS and native Android are separate pools. Tell us the OS versions you support, whether the codebase is SwiftUI or UIKit, Compose or Views, and we match on that.
Yes, they are different pools with different strengths. Flutter suits highly custom interfaces rendered consistently across platforms; React Native suits teams already sharing code and TypeScript with a React web app.
Share your requirement and you get interview-ready profiles within 24 hours, with most engagements starting inside 40 hours of the first call.
We replace them, at no cost and with no notice period. Every placement runs a 15-day risk-free trial, and you keep everything produced during it.
Yes. Engagements run full-time, part-time or hourly with no long-term lock-in, so you can add engineers for a push and release them afterwards.
You do, entirely. We sign an NDA before any technical conversation and assign all IP to you as work is delivered.
