HubSpotQuestions, answered.
Why choose cross platform over native?
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.
Which is better — React Native or Flutter?
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.
How much does it cost?
Most cross-platform MVPs ship in ~45 days for under $15k. Costs and timelines rise with complex integrations (payments, SSO, enterprise compliance).
Do cross platform apps feel slower than native?
Not with proper architecture. We use native modules where performance matters — so your users won’t feel the difference.
Will we own the code?
Yes. You own repos, infra, and IP from day one. We document everything so your team (or ours) can keep building.
Can you handle enterprise compliance?
Yes. We support SOC2, HIPAA, PCI, and integrate with enterprise security (SSO, MDM, audit logs).
