Common questions about cross-platform development
Cross platform can cut build time and cost by ~40%. It’s great for MVPs and many production apps. For heavy device integrations, we may still recommend native.
Both are solid. React Native works well if you need strong web + mobile alignment. Flutter shines when you want consistent UI across platforms. We’ll recommend based on your goals.
Most cross-platform MVPs ship in ~45 days for under $15k. Costs and timelines rise with complex integrations (payments, SSO, enterprise compliance).
Not with proper architecture. We use native modules where performance matters — so your users won’t feel the difference.
Yes. You own repos, infra, and IP from day one. We document everything so your team (or ours) can keep building.
Yes. We support SOC2, HIPAA, PCI, and integrate with enterprise security (SSO, MDM, audit logs).
