FAQ

Mobile App Development questions

Answers to what businesses in California ask us most. Have a different question? Ask us directly.

Ask a question

How much does it cost to develop an app in California?

A focused MVP costs far less than a full-featured platform. Pricing depends on features, platforms (iOS, Android or both), integrations and admin requirements. We provide a milestone-based fixed quote in USD after a free scoping call.

How long does app development take?

A typical MVP takes 8–12 weeks. More complex apps such as marketplaces, delivery apps or fintech platforms usually take 3–6 months, delivered in 2-week sprints with demos.

Should I choose Flutter or native development?

Flutter lets you launch on iOS and Android from one codebase, saving 30–40% time and cost — it is our default for most startups. Native development is best for apps needing heavy device-level performance.

Will I own the app source code?

Yes. You receive 100% ownership of the source code, designs and store accounts, protected by an NDA from day one.

How do you work with clients in California?

We work remotely with businesses in California, USA from our delivery centre in India, with scheduled calls in your working hours (EST / CST / PST overlap), shared project dashboards and a dedicated project manager. Quotes and invoices are in USD.
