Top 50 Cross Platform App Developers in Seattle
The Best of December 2024
Looking for a top cross platform mobile app development company in Seattle?
Cross-platform mobile applications have benefits that outweigh those of native applications if your users interact with your business on both Android and Apple products. Cross platform app development entails building a mobile app that’s compatible with multiple operating systems. Cross-platform, or hybrid apps, use a single codebase, which means you don’t need separate apps with separate technologies to appeal to customers using Android or iOS. Because of this single codebase, cross platform apps are less costly to create and maintain.
Most hybrid apps will use either Ionic or React as a development framework. React is a JavaScript framework that allow apps to support Android and iOS natively, while Ionic uses JavaScript, HTML5, CSS, and Sass for hybrid apps, desktop apps, and progressive web apps. Choosing an app developer with the right skillset to fit the technology framework your app needs is a good place to start when interviewing app development companies.
To assist you in your search for a partner, we’ve compiled this list of the top cross platform app developers in Seattle. Browse descriptions, feedback, and awards to find which can best suit your company’s needs.
