The app is quite useful for quickly getting summaries of books and getting a general idea of their content. The concept is good, and the interface is user-friendly.

However, having read some of the full books myself, I’ve noticed that some summaries don’t fully capture the most important ideas or key principles. They often lack concrete examples and the depth that a complete book provides. So, while Headway is a convenient tool for quick insights, it definitely cannot replace reading the entire book for a full understanding.

Also, the quality of summaries can be quite uneven, which affects the overall experience.

In short, Headway is a handy app for getting a taste of many books, but it’s important to remember its limitations as a summary tool.
