Mobile App Developers for California Start-ups and Businesses

California businesses expect apps that are fast to ship and pleasant to use. Our mobile application development team handles the whole journey — planning, design, development and testing — so a quality app reaches your users in less time, and it keeps engaging customers long after launch.
Quality comes first: every build is reviewed and tested before you see it, and free technical support is part of the service. We treat your app as part of your business, not a side project, and design it to give that business momentum.

Built In to Every App

Key features, relevant content and an attractive interface are what lift an app above a repackaged website. Each app we deliver has:

What a Mobile App Does for Your Business

    Customers can reach you from anywhere, which makes staying with you the easy choice.

  • Be visible anytime

    Your products and services are available around the clock, on the device people carry everywhere.

  • Add value

    Saved details, loyalty features and faster ordering make every visit more useful.

  • Build your brand

    Your icon on the home screen is a daily reminder of who you are.

  • Stand out

    A well-made app sets you apart from competitors who only have a website.

Working Across the Pacific Time Difference

India (GMT +5:30) is 12½ hours ahead of California during daylight saving time and 13½ hours ahead in winter. We fix a call time that suits both sides — usually the start of your morning — and the development day happens overnight for you, so there is fresh progress to review when you log in.
Choose a fixed-scope project, or hire a dedicated developer full time, part time or by the hour with weekly or monthly billing. Both options give you direct contact with the people writing your code. See our US app development page for more.
