BW's mom ,

Highly recommend

We used this APP for couple of months. We immediately fell in love with the easy to use platform, clears &organized layout, and thorough book information.
My favorite parts are the data collecting and editor’s pick. I can clearly tell my boy’s reading level, and how much we completed so far throughout the year.
Editor’s pick never disappoint me. As a busy working mom, it provides a variety of great quality books for my kid to explore. My 9 year-old boy is curious about what is happening around us. During earthquake time. we were introduced to the “what was “series. He started from “what was the earthquake”, and read through almost all of them. Again, in this pandemic time, we found a “Science comic “book “called “Plague “. During our stay home time, reading together, becomes our bounding time.
Highly recommended !

Great App for both kids and parents!

This App offers a tremendous amount of book resources for different reading levels. There are also great book lists with interesting topics. It’s a huge help for parents who have no idea what appropriate books to offer their kids at different ages/levels. Also as a mom with very little experience and knowledge of English reading, I extremely appreciate the “homework” this App has done for parents like me. A big shout-out to the developers!

Great App! Highly recommend!

Love this app! Easy to use and very helpful when I try to find the right book for my kid. My favorite feature is the “scan” function. You can simply scan the book and find the reading level of it. How cool is that! I also keep a list of all the books people recommend to me in the “to read” log so I can easily find them when needed. Thank you so much!
