Remove unnecessary fields

From the users' perspective, the shorter the better, especially when it comes to mobile forms. One input for a name and surname reduces interaction costs and helps finish a form a bit faster. Plus, the internet is incredibly multicultural, so creating a single field for a full name can be more inclusive.

However, keep in mind that most people care about their names, so using them wrong can ruin the impression and break trust. If you decide to leave only one name input, make sure you know how to identify the first and last name and use it under the given context.
