Ah what an app. Highly recommend SumizeIt Book Summaries. Best of all I have experienced in market. iOS app is rock solid and performs each time. Plus their service and support is incredible. Also they have frequent newsletter with a surprising book summary suggested to listen too. Love it. Can be turned off if someone would not like it. SumizeIt Book Summary app team, great job and well done. Thanks for your efforts.

Very good development in last months. Content updates on a regular basis and UI is getting better and better.


Great product. Have used them for a long time. One of my favorite things about them is that they are able to summarize a whole book into just 10 minutes.

As someone who's been a paid yearly subscriber for 20+ years to Executive Book Summaries, I found the lifetime deal hard to resist. In reading a few of their summaries, I thought they capture the book's essence, theme, and highlights pretty well. The language is easy, and straightforward to read and understand. I'm really looking forward to their video summaries, and how they work. Overall, happy with purchase.
