How do you hire a mobile app developer in Seattle for your business? To find the right company, follow these steps:

  1. Identify your project needs. Before releasing an RFP or meeting with a potential partner, compile a list of your requirements. Include designs, features, and functionalities to get input from the app developers you’re talking to.
  2. Choose a mobile app development platform — iOS vs. Android — and if you want to build a native, hybrid, or cross-platform app. Ask yourself if it’s important that the app is available on both the App Store and Google Play. Can you build natively while staying on budget?
  3. Read client testimonials, reviews, and case studies to get a better understanding of what your top contenders are capable of doing. If you find a project similar to yours, examine how they went about the project, how easy it was to communicate, and what their shortcomings were.

With hundreds of app development companies to choose from, how do you get started? Our list of the best app development companies includes client reviews, minimum project size, team size, specialty services, and client focus. Define the services you need, project goals, and budget to begin narrowing your choices. If you need help creating a shortlist, tell us about your project and receive personalized recommendations.
