What app has the best usability?
Tell us what app you think is easiest to use. We'll collect your responses in an article for World Usability Day.
World Usability Day is coming up on November 13, 2025. On this day, we highlight the importance of good usability, and why it is important that we make all of our interfaces and documents easy to use.
You can define usability in different ways. One academic definition uses terms like learnability to describe how easily you can learn the interface, discoverability for how easily you can uncover new features, memorability to describe how well you can remember how to use the system again later, and error rate for how the software allows you to do things you shouldn't.
My personal, less formal definition of usability is can real people do real tasks in a reasonable amount of time. That means a software interface should allow a real person to accomplish real world tasks such as typing a document (for a word processor) or accessing a website (for a web browser) or playing a song (for a music player) without having to spend a ton of time figuring out what to do. For a document, such as a set of instructions, this means a real person should be able to follow the instructions to complete a real world task such as how to change the toner in a printer, or how to make coffee in a new coffee machine, or how to set up a new mobile phone.
With this formal and informal definition, we want to collect a round up article about what is an application that you find easy to use? This could be any app, from something as simple as a favorite music player that you find easy to use, or an open source video editor that you use to edit and remix videos. It's okay if the application is specific to a particular user group or use case; if it is, indicate that in your response. After all, we wouldn't expect a programmer's editor or Integrated Development Environment ("IDE") to be very easy for someone who had never programmed before.
Contact our editors, and tell us what app you like. Also write one or two paragraphs to explain why you find this easy to use. We'll collect your responses in an article for World Usability Day.
