Mobile App Development in San Francisco.
iOS & Android apps built with Flutter and React Native. Mojo Studio delivers mobile apps for founders and businesses in San Francisco, senior engineers only, weekly demos, full IP ownership.
Built right,
shipped fast.
We build native-feel mobile apps on Flutter and React Native — a single codebase that ships to iOS and Android simultaneously, cutting build cost by up to 40% versus separate native teams without sacrificing 60fps performance or App Store polish. Deep hardware integration (camera, biometrics, push notifications, offline-first sync) is handled in-house, not bolted on.
Built for San Francisco's market.
Bay Area founders raising smaller, leaner rounds in the current funding climate are pairing a compact US-based product team with an India-based engineering studio to extend runway between raises, especially for well-defined mobile and web builds that don't require someone physically in the room. San Francisco's density of technical, well-funded buyers also means studios are evaluated on shipped work and process rigor rather than pitch decks — a market that rewards a portfolio of production apps over promises. AI-native product companies based here, in particular, need fast iteration on user-facing surfaces while their core teams stay focused on model and data work, which is a natural handoff point for an external build partner.
San Francisco's venture-backed startups and ai/ml product companies businesses have specific needs when it comes to mobile apps — this is the local context that shapes how we scope every San Francisco engagement, not a generic playbook applied everywhere.

Mobile Apps FAQ.
Flutter tends to win for pixel-perfect custom UI and consistent 60fps performance across both platforms; React Native wins when you want to share code with an existing React web team. We scope this in our first call based on your product and team, not a fixed preference.
