Mobile App Development in Los Angeles

ClearSummit excels in native iOS, Android and React-Native. We have been making our own custom mobile apps since 2010, and have been creating custom mobile apps for our clients since the early days. As time moved on and technology evolved, we've adapted to evolve with it... and we haven't stopped.

Starting with the core functionality of Objective C, Github, and Python, and evolving through Swift’s heyday to what is now leading-edge in versatile mobile development - React, we have maintained a deep working knowledge of the best ways to build and evolve custom mobile applications for any mobile device.

We build your mobile functionality in native apps like Google Android and Apple iOS, or by utilizing the latest hybrid frontend tools. Those same backend foundations allow us to create both mobile apps and web products.

We value efficiency and performance, and those values inform the approach we take with each project.

That approach involves walking you through the analysis of the best strategies for your mobile app or web product, and develop and actionable plan to maximize the value in the hours we spend when building your app.

ClearSummit offers UX/UI design & full stack engineering solutions for your business and target customers. Our in-house team focuses on efficient product design and agile development, keeping your long-term tech goals in mind while providing you with a lasting product and start-to-finish processes, so you can focus on your core business.

Design & Discovery Consultation

Timeline: 2-4 weeks

Most of our clients start in a room with top engineers, designers and project managers that help them understand the underlying methodologies, in-house development processes and technology stacks. Once you’ve gone through the initial steps, we demonstrate your ideas against your targeted user base and derisk the path to a viable product. Each Discovery is customized based on the development project and the unique challenges you’re solving for. Some facets of the Discovery phase may include reviewing UX design, web development components, backend requirements and other technical audits of existing code.

During Discovery, we'll answer questions like:

  • "What's the next step?"
  • "How difficult is this problem?"
  • "What's the best solution?"
  • "What can we expect to see from the development team?"

Discovery Deliverables may include:

  • User Flows & Personas
  • Project Scope
  • Technical Derisking
  • Code Audits
