Book summary apps

I have known for some time that the apps on my phone are out of control.  In an effort to be purposeful in my use of the web, I started deleting apps.  I came across one, Blinkist.  There was nothing on it so I must have either never used it or my free trial ended.  

As I have mentioned before, I am not very good at collecting or curating.  This tool, Blinkist, provides summaries of nonfiction books in 15 minutes or less.  Here is a review of the tool and more details about how it works. 

So this made me think about how this might work for PLNs.  I have been in communities where individuals read books and then post about them. The communities weren't only about the books but if someone read something helpful or discouraging, they would post. 

I have been thinking more about these book summary tools.  Here is a 2020 summary of 10 different ones.  

What do you think?  Do you or would you use a book summary tool?
