The difference between these two kinds of applications is their approach to development. Standard applications are created for a wider audience with the same purposes. For example, Adobe Photoshop or Microsoft Office. This app type has a fixed set of features and tools for everyone. Whereas, customized applications are built for a specific range of users with certain goals and desired results. It can be a unique application for your company's workflow management with standout tools, specific opportunities, design, etc., or it can be your own application for any purpose you like.
