An app’s first interaction should be as easy as possible. Many apps ask for sign-up information at the first interaction. This can greatly hinder user adoption. Users want to see how they will gain value from an app before they are willing to give out their name, email, etc. Zite, the media customization aggregator, handles this by prompting users to pick topics they are interested in before asking for sign-up information. This simple interaction creates commitment that mitigates the pain of entering personal data.

It is common practice for a product to be boiled down its essential functions, which define its form. It is the designer’s goal to make the application as simple as possible. The product should be useable and useful from the very beginning. It should always be the goal of the designer to limit the need to explain the app. However, not all digital products can be inherently intuitive.
