Common questions from San Francisco founders
What does custom mobile app development for a startup in San Francisco actually cost?
San Francisco agencies charge $150–$300/hr for custom mobile development. Vnta scopes a fixed price during a free discovery call. Custom doesn't have to mean enterprise-priced.
What's the difference between custom and template-based mobile development?
Custom development builds every screen, component, and interaction specifically for your product. Template-based adapts a generic framework.
Is custom mobile development worth it for an early-stage startup?
If your differentiation is in the UX, data model, or specific workflows — yes. We advise honestly during scoping.
Do you build custom for both iOS and Android?
Yes. We use React Native for a shared custom codebase that runs natively on both platforms.
How long does custom mobile development take?
6–12 weeks depending on the depth of customisation.
Do I own all the custom code?
Fully. Every custom component, screen, and integration — along with all design files and accounts — is transferred on delivery.
