No matter how well-designed your user interface may be, at some point or another, people using it are going to have to wait for something to load. The loading time could harm the overall experience. Making users wait too long for your app to load can make users impatient. If users get the feeling, they’ll abandon your app and go somewhere else. Hopefully, there are a few things you can do to speed up your user’s sense of time and make them feel like your app loads faster than it does.
If the user’s connection is slow, it can take a while for an app to populate content on the screen. A user’s wait time begins the moment they initiate an action, and the worst case is when they don’t have any indicator the app has received it. When the app fails to notify users that it needs some time to complete an action, users often think the app didn’t receive the request, and they try again. Plenty of extra taps has resulted due to a lack of feedback. To make people happy, we need to give an indication that something is happening, offer a visual feedback.
Static progress indicators are the ones that have an unmoving image or text, such as “Loading…” or “Please wait…” to indicate that the request has been received. While any feedback is better than none, static indicators are bad UX. Users don’t have any indicator that content is being loaded, so they aren’t sure if the process is actually stuck.
