Ask a specific question
What's included in a mobile build?

Product discovery, UX, native iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose) or cross-platform (Flutter/React Native), backend integration, App Store and Play submission, and post-launch analytics and crash-free monitoring.

How long from kickoff to store release?

MVP with a focused feature set: 10–14 weeks. Full production app with offline, biometrics, deep-linking and analytics: 4–6 months. We ship to TestFlight and internal tracks from week three.

How do you handle security and store compliance?

Certificate pinning, secure enclave / keystore-backed credentials, biometric auth, OWASP MASVS aligned code review, and full support for Apple Privacy Manifests, ATT and Play Data Safety declarations.

Can you take over an existing app?

Yes. We start with a technical and store-health audit, stabilise crashes and review pipelines, then either co-develop with your team or run the app end-to-end as a managed product.
