Pros: 

How easy to use and accessible it is

Cons: 

The app is no where near as good as the website version in terms of detail or features

My reading and listening skills have improved so much since using Duolingo, I couldn't recommend it more. I'm not naive in thinking it will make it fluent as it's not the best for speaking skills but has vastly helped me improve and build up my language confidence.
