Apps are usually built by software developers who specialize in mobile software. They may be experts in just one mobile software development language or know several, and may have expertise in front-end or back-end web development. No matter what kind of phone or tablet you carry, there are hundreds of apps for it — and new ones seem to be added to the app stores every day. Before you hire an app developer, it’s important to have specific goals for your app and a clear idea of its purpose. When your company is ready to build an app, you can hire a freelance app developer or work with an app development company that can also support the app after it’s launched. It’s important to know whether you’ll need the developer to provide ongoing maintenance and support or if your internal IT team can maintain it after its launch.
