If you're working with a UI and UX design agency, they might ask for your input about your app’s user interface. This is why it's essential to understand the features of a good user interface and why it's so important to your product’s success. Educating yourself about this topic will lead to more meaningful conversations with your user interface design team.
A good user interface must be:
- Intuitive–Users should be able to figure out how to use your product without reading lengthy instructions. The best way to achieve this is by using familiar conventions (like a hamburger menu for navigation) and making features self-evident (like using icons that are easily identifiable).
- Simple and uncluttered–A good user interface is uncluttered and easy to understand. It should only include elements that are absolutely necessary and nothing more, which makes it easy for users to find what they're looking for and use your product without getting overwhelmed.
- Consistent–All the elements in your user interface should be consistent with each other. This includes color schemes, typography, iconography, and overall design language; all of these elements make for a more cohesive experience that's pleasing to look at and easy to use.
- Responsive–A good user interface should be appealing to look at and work well on all devices (desktops, laptops, tablets, and smartphones). This is important because more and more people are using mobile devices to access the internet.
- Flexible–A good user interface should be flexible and be able to adapt to different screen sizes, resolutions, and orientations (landscape or portrait) because you never know what kind of device your users will be using to access your product.
- Accessible–A good user interface must be usable by people with disabilities. This includes providing text alternatives for images, allowing users to adjust font size, and using high-contrast color schemes.
The easiest way to determine whether your user interface is up to the mark is to conduct UX testing–we dive deeper into this in our UX research guide for product managers.
Why is a good user interface so important?
Having a user-friendly interface means that your product is easy to use, which means more people will be inclined to use it. It also makes your product more enjoyable and fun, which keeps people coming back. This is supported by data from Amazon Web Services, which shows that 80% of users won't come back to a website after having a bad user experience.
A well designed and thoughtful user interface also shows that you care about your users and their experience with your product. This helps build trust and loyalty, which are both important for any business.
A good user interface is also important for conversions. According to Forrester, a better user interface can raise your website's conversion rate by up to 200%, and 80% of online businesses fail to improve their conversion rate because their products are not usable, according to data from Uxeria.
Last but not least, a good user interface can actually help you save money because it can help you avoid costly support calls and issues created by a poor user experience. So, if you're a new digital business or you're thinking about redesigning your product's user interface, keep these features in mind. They'll help you create a user interface that's not only good for your users, but also good for your business.
