FAQ on iPhone app development agency in Los Angeles

  • What is your San Francisco iOS app development company process?

    During any of our mobile app development or web application development processes, we tend to keep to the following structure:

    1. Collection of requirements and creating an initial concept

    We begin with collecting necessary information and the desired requirements. And to build a clear vision of the required functionality and visual aesthetic, we build a high-level concept. You can imagine it as a prototype for a car; it’s far from driveable, but the model helps engineers to visualize and analyze all of its parts.

    2. Define an MVP and its roadmap

    Once we have a solid product future vision, we begin to define a business roadmap of how to reach a proof-of-concept design. Including only the core features into an MVP, while creating a plan for secondary features.

    3. Design a data structure and API

    Most modern apps offer a simple interface for back-end functionality. Whether it's a mobile or a web app, it directly interacts with the end-user with various data via its server. Therefore, the success factor of an app depends on the quality of the back-end. Thus, when building a new system, we usually start with the back-end. But if you have your back-end prototype, we will try our best to work with it.

    4. Proof of concept

    Next, we create a proof of concept prototypes, allowing our team to verify assumptions to avoid potential pitfalls or failures.

    5. Laying a foundation

    Once we confirmed the approach to building the intended features, we start creating a software foundation. That includes a design system, UI/UX design, interactions, widgets, along other tools and utilities.

    6. App development

    During this step, we build each app functionality iteratively, ensuring we are moving fast while maintaining a solid architecture.

  • What technologies do your iPhone app developers in San Francisco use for mobile application development?

    We develop mobile apps using native programming languages such as Swift for iOS, and Kotlin for Android. However, we don't use ReactNative, Flutter, or any hybrid app approaches. We believe that a sufficient quality, desirable performance, and good user experience design can only be achieved using native languages.

  • What other services your iPhone app development company in San Francisco offers?

  • How long does it take to create a simple app with your SF iPhone app developers?

    Our main goal is not to develop an app fast and hand it back to the client. Instead, our focus is to build a strong relationship so our team can produce long-term value to the client's business over the years. Mostly, we tend to work on complex applications where we need about 9 months of design and development to release its first version. And exactly with these clients, we can develop small apps to test their ideas within 3-4 months.

  • Where does your Bay Area iOS app agency operate beyond San Francisco?
