Project background

4books is the app created by Marco Montemagno to learn from the best business and personal growth books in just a few minutes: summaries you can read or listen to in 15 minutes, along with exclusive podcasts and the news of the week. It is designed for people who want to keep learning even when they are short on time, while doing something else.

Project

Learn something in 15-20 minutes by reading or listening to book summaries, wherever and whenever you want.

That was the goal: an app designed for people with little time to spare. We developed the iOS and Android app and the website with React Native, starting from an in-depth design phase together with the 4books PM to create an intuitive interface.
