Swift and Kotlin apps engineered for performance, offline reliability, and the platform conventions your users expect.

Discovery sprints, user research, journey mapping, and prototyping to make sure we build the right thing.

We handle submission, review compliance, screenshots, and store optimization so launch day is smooth.

FAQ
Most MVPs ship in 8–12 weeks. Complex products with backend, integrations, or regulated flows usually land in 3–5 months. We'll give you a hard number after the Discovery Sprint.
Both. We help you pick based on your users, timeline, and feature set. When speed matters we lean Flutter or React Native; when performance and platform fidelity matter, we go native.
You do — 100%. Code lives in your GitHub org from day one, and all designs, credentials, and infrastructure are yours.
Absolutely. We plug in as a squad or as individual specialists (iOS, Android, backend, product design) and follow your existing rituals.
