App context is a simple todo task app.

So, what would be the best way to convey to the user the task already exists on the list?

Basically, I want to keep the message and prompt as humorous and less annoying respectively.

  • An humorous way could be to talk about "senility" but not sure that it is a good thing for your app.

    Why a to do task list needs to provide this information? I am assuming that duplicating a task causes no harm in a to do list... as I understood your question.

    I don't think this sentence is that long. But if you want a short one, you can try a "Oh ! Again ?!"

Best way has fulfill two needs:

  1. Explain the user error
  2. Stop the error from occurring

This is best done with an alert, typically. The language you use is up to you. I'd suggest something like "D'oh! You already have [taskname]"

But be aware of the usability challenges associated with it. Does the alert offer a way to retain the data, meaning return to edit? If not, what is the action?

In my experience the language is important but the functionality wins the day. Or, the way I think of it, users come for the functionality but stay for the form.

  • yeah fully agreed on functionality wins the day
